FIELD OF THE INVENTION

The present invention relates to a gemstone, and more particularly, to the cut of a gemstone.

BACKGROUND OF THE INVENTION

A basic understanding of diamond cutting is provided to present a better understanding of the gemstone cut and method of cutting. Referring toFIG. 1, when drawing a sketch of a diamond on a flat piece of paper, the lines of the diamond are being drawn directly, and as a result, indirectly, there is the formation of “facets.” The sketch has only two dimensions, and all of the lines and “facets” are in the same, one, geometrical plane (the flat piece of paper). When cutting a diamond the situation is reversed. The facets are being formed directly, and as a result, indirectly, there is the formation of lines. The actual diamond has three dimensions, and each facet is in its own separate geometrical plane.

A diamond in the rough has no facets, and hence, no lines. After the first facet is formed, there is also no line. The first line on the diamond can be (indirectly) formed when a second facet is “cut”, and when the second facet intersects or meets the first facet. Where the second facet meets the first, a line is formed. The more degrees the second facet is “cut” away from the first facet, the more pronounced (or stronger) that line becomes. The fewer degrees the second facet is “cut” away from the first facet, the less pronounced (or weaker) the line becomes. In other words, the strength of the line between two facets i.e. how pronounced that line is can give approximate information as to how many degrees away from the first, the second facet lies.

Referring toFIG. 2, the position of the line between the two facets gives accurate information as to the direction from which facet B was cut on to facet A. There are four initial directions facet B can be cut from: Higher SeeFIG. 2a(facet B is cut on a higher angle than facet A), Flatter SeeFIG. 2b(facet B is cut on a flatter angle than facet A), Right SeeFIG. 2cand Left SeeFIG. 2d. From these four initial directions there are combinations of directions from which facet B can be cut from facet A: Higher and Right, Higher and Left, Flatter and Right, Flatter and Left. In four of these combinations facet B can be more degrees higher or flatter than right or left SeeFIGS. 2e-2h. In four of these combinations facet B can be more degrees right or left than higher or flatter SeeFIGS. 2i-2L. In four of these combinations facet B can be equally higher or flatter as from right or from left SeeFIGS. 2m-2p. A demonstration of these combinations is shown inFIG. 2with illustrations of a rough diamond with facet A as the large circular facet, and facet B being cut on to facet A with the position of the tell tale line giving accurate information as to where facet B came from.

(An efficient and effective method for cutting a gemstone is needed for providing a brilliant reflective cut).

SUMMARY OF THE INVENTION

It is, therefore, an objective of the present invention to provide a cut gemstone and methods of cutting a gemstone. An exemplary gemstone cut may be cut from a round stone. The gemstone may have a crown having a table surrounded by eight star sets. The eight star sets may be surrounded by eight bezel facets. The eight bezel facets may be surrounded by 8 pairs of upper girdle facet sets. Each upper girdle facet set may have one primary upper girdle facet and two secondary upper girdle facets. The two latter secondary upper girdle facets may be adjacent and parallel and lined up to each other and the girdle facet below them. Each star set may have one primary star set and four secondary star facets.

According to an exemplary embodiment of the present invention, the gemstone may incorporate the following embodiments. In one embodiment, one of the secondary upper girdle facets of each upper girdle facet set may be a narrow rectangular facet adjacent and parallel to a girdle facet of the gemstone, and lined up with that girdle facet. That narrow rectangular secondary upper girdle facet may also be adjacent and parallel to the triangular secondary upper girdle facet above it lining up with it. In this embodiment, two of the secondary star facets of each star set may be narrow rectangular facets adjacent and parallel to the table and to the triangular secondary star facets underneath them lining up with those triangular secondary star facets. In another embodiment each upper girdle facet set may have one of the secondary upper girdle facet, as one narrow rectangular facet adjacent and parallel and lining up to a girdle facet of the gemstone and may have an additional secondary upper girdle facet as a second narrow rectangular facet adjacent and parallel and lining up to the first narrow rectangular facet, all lining up with each other, and the triangular secondary upper girdle facet directly above them. In this embodiment, each star set may have two of the secondary star facets as two narrow rectangular facets adjacent and parallel to the table and each star set may have two additional secondary star facets as two second narrow rectangular facets adjacent and parallel to the first narrow rectangular facets. The narrow rectangular facets may line up with each other and the triangular secondary star facets directly underneath them. In addition, these above embodiments may have the bottom having 40 lower girdle facets. Another embodiment may have the bottom having 24 lower girdle facets SeeFIGS. 23cand24c.

DETAILED DESCRIPTION OF THE INVENTION

According to an exemplary embodiment, the stone is blocked like a round stone (BR)300as shown inFIG. 3A-3C. There are eight bezels302on a crown304between 30°-36° (to the Girdle306), and a table308. The table308may be about 58% (of the diameter) give or take a few percentage points. A total of nine blocking facets may be on the crown304. There may be eight pavilions310on the bottom of the stone 40.5°-42.5° (to the Girdle306). A culet312may be a point with no facet. There may be no culet or a very small culet. A total of eight, (or nine if culet is included), blocking facets may be on the bottom.

Referring toFIGS. 4A-4C, a full cut or (brilliandeered) stone400according to the exemplary embodiment may include eight star sets414(on a crown404, off a table408). Each star set414may have one primary facet416and four secondary facets418. Two of the secondary facets may be narrow rectangular facets giving two lines off the table408instead of one in order to strengthen the reflection. According to a second exemplary embodiment, this double table line can be a triple table line by adding one more rectangular facet420under each of the two rectangular facets on each star set414. As a result, each star set414would have six secondary star facets418. A total of 40 star facets may be on the crown404according to the first exemplary embodiment. A total of 56 star facets may be on the crown404according to the second exemplary embodiment with triple table lines.

There may be eight pairs of upper girdle facet set422, each one of the pair having one primary upper girdle facet424and each one of the pair having two secondary upper girdle facets426. One of the secondary upper girdle facets426may be a narrow rectangular facet off the girdle adjacent and parallel and lining up with the girdle facet406directly below it. A total of 48 upper girdle facets are on the crown404; totaling 88 brilliandeering facets on the crown and altogether 97 facets on the crown404according to the first exemplary embodiment. A total of 104 brilliandeering facets on the crown and altogether 113 facets may be on the crown404according to the second exemplary embodiment.

There may be eight sets of lower girdle facets428(on the bottom): each set may have one primary facet430and four secondary facets432. A total of 40 lower girdle facets are on the bottom; totaling 48 facets on the bottom (49 if (very small) culet facet412is provided).

There may be sixteen narrow rectangular secondary upper girdle facets426above the girdle406located directly above the narrow rectangular girdle facets406adjacent and parallel and lined up with the girdle facets406according to the first exemplary embodiment. There may be additional narrow rectangular secondary upper girdle facets426that may be adjacent and parallel and lined up with the original narrow rectangular secondary upper girdle facets426. A total of 161 facets may be on the stone400according to the double table line of the first exemplary embodiment. A total of 177 facets may be on the stone400according to the triple table line of the second exemplary embodiment. A total of 194 facets may be on the stone according the triple table line of 2ndexemplary embodiment combined with triple girdle line of 2ndexemplary embodiment. An additional facet may be provided if a culet facet412is provided.

Lines between facets (where one facet meets a second facet) are labeled rib lines; if one of those facets is the table308,408the line is labeled a table line; if one of those facets is the girdle306,406the line is labeled a girdle line. Stronger lines are labeled primary lines; weaker lines are labeled secondary lines. As a result of the added secondary brilliandeering facets, the form of the bezels and pavilions are slightly changed each with 4 additional primary rib lines. The form of the table may be changed from an octagon shaped facet to a 16 sided facet as a result of the added secondary star facets. The round stone300(BR) has 8 table lines; the stone400, according to the exemplary embodiment may have sixteen primary table lines in symmetry with the sixteen girdle facets. This style of girdle faceting brilliandeering may be applied to any cut or shape (stone) when appropriate, as one skilled in the art would appreciate.

Referring toFIG. 5A, inception of primary star facet416is shown. SeeFIGS. 3A and 3B. The starting point of primary star facet424is cut directly between two bezels302approximately 10 degrees flatter than the bezels302. Two points of primary star facet (“PSF”)416reach about 80% to the center of the table lines and one point reaches about 60% to girdle306referring toFIG. 5B, the finished primary424star facet ofFIG. 5Ais shown. This primary star facet may be cut as a secondary bezel facet (seeFIG. 16A) resulting in a second method of star and a pair of upper girdle facet sets. The starting point is where two table lines meet one rib line.

Referring toFIG. 5C, inception of this secondary star facet418may be on left point of PSF416. The secondary star facet418is cut from flatter and left of PSF416. The secondary star facet418may be cut as flat as practically possible so that the middle point drops toward girdle as minimum as possible. The left point reaches approximately 20% past center of bezel302indicated by arrow and right point reaches approximately 20% past center of primary star facet416indicated by arrow. Referring toFIG. 5D, the finished secondary star facet418ofFIG. 5Cis shown.

Referring toFIG. 5E, inception of the second secondary star facet418may be on middle point of previous secondary star facet418. The second secondary star facet418may be cut from higher than the previous secondary star facet418. The left point may reach to the center of the bezel302and the right point may reach to the center of primary star facet416. The horizontal rib line of this second secondary star facet418may be parallel to table line of previous secondary star facet418in order to produce a double table line effect. The middle point of this second secondary star facet418may reach to about 50% toward girdle of primary star facet416. If triple table line is desired, the middle point may reach to about 35% toward girdle of primary star facet416and the procedure of the previous second secondary star facet418is repeated. Beginning at the middle point of previous secondary star facet418, the cut is from higher than previous secondary star facet and keeping the horizontal rib line of this secondary star facet418parallel to previous horizontal rib line. This provides equal spacing of three horizontal lines at an equal distance. Middle point of this secondary star facet418may reach to about 55% toward girdle of primary star facet416. Referring toFIG. 5F, the finished secondary star facet418ofFIG. 5Eis shown.

Referring toFIG. 5G, the same procedures as secondary star facets418is followed with the exception that the inception of this secondary star facet is on the right point of the primary star facet416. This secondary star facet418is cut from flatter and to the right of primary star facet416. The cut may be as flat as practically possible so that the middle point drops toward girdle as minimum as possible. The right point reaches approximately about 20% past center of bezel402. The left point may reach towards the center of primary star facet416forming very small vertical rib line when secondary star facet418ofFIG. 5G“bumps” into secondary star facet ofFIGS. 5C and 5D. Referring toFIG. 5H, the finished secondary star facet418ofFIG. 5Gis shown.

Referring toFIG. 5I, the secondary star facet418may be cut following the same procedure as the secondary star facet ofFIG. 5E. A triple table line effect may be produced as previously described inFIG. 5G. Referring toFIG. 5J, the finished secondary star facet ofFIG. 5I418is shown.

The two narrow horizontal rectangular secondary star facets418of the star set414adjacent to (off) the table may be past the centers of the bezels402. When star414sets on right and left are completed the right and left points of the finished star set414may be “bumped” back to centers of bezels402forming a very small vertical rib line at the center of each bezel402. In another embodiment the two narrow rectangular secondary star facets may just reach centers of bezels. Hence there would be no “bumps” between star sets.

Referring toFIG. 6A, the inception of a first primary upper girdle facet424of a pair is shown. The starting point is the point where two girdle lines meet one rib line. The primary upper girdle facet424is cut approximately 7° higher than bezels302. This primary upper girdle facet424may be cut from higher and to the right of bezel302on left side of aforesaid rib line. The left point reaches about 85%-90% to center of aforesaid bezel302(indicated by arrow). There are two middle points. The middle point advancing up the rib line toward the primary star facet416touches the point of that primary star facet416. The other middle point directly below (indicated by arrow) advances into the girdle406and reaches into the girdle406identically as deep (into girdle) as the middle point of bezel402. (Point #1middle point of bezel402in the girdle406) (Point #2middle point of primary upper girdle facet in the girdle). Eventually, when a line is formed between those 2 points, that line will be parallel to the table408. As a result the right point ends up approximately 33% to the center of bezel402on right side of rib line. Referring toFIG. 6B, the finished first primary424upper girdle facet424ofFIG. 6Ais shown.

Referring toFIG. 6C, the inception of a second primary upper girdle facet424of a pair is on the right point of first primary upper girdle facet424. The second primary upper girdle facet424may be cut from right of first primary upper girdle facet424and hence forms a vertical rib line between the two primary upper girdle facets424. That rib line advances to left to the two middle points of the first primary upper girdle facet424(indicated by arrow). The right point of second primary upper girdle facet424may reach about 85%-90% to center of bezel402on right (indicated by arrow). Referring toFIG. 6D, the finished second primary upper girdle facet424ofFIG. 6Cis shown.

Referring toFIG. 6E, shows the inception of a secondary upper girdle facet426which is on the left point of a primary upper girdle facet424. The secondary upper girdle facet426is cut from higher and left of first primary upper girdle facet424. The cut may be as high as practically possible so that the middle point of this secondary upper girdle facet426may not advance more than about 30% up the first primary upper girdle facet424and the left point of secondary upper girdle facet426reaches 20% past center of bezel402(indicated by arrow). The right point reaches past the rib line between two primary upper girdle facets 10% into second primary upper girdle facet424on right. Referring toFIG. 6F, the finished secondary upper girdle facet426ofFIG. 6Eis shown.

Referring toFIG. 6G, the inception of another secondary upper girdle facet426is on middle point of previous secondary upper girdle facet426. This secondary upper girdle facet426may be cut flatter than previous secondary upper girdle facet426. The left point reaches towards the center of bezel402(indicated by arrow). The right point reaches towards the rib line between the two primary upper girdle facets424(indicated by arrow). The horizontal rib line of this secondary upper girdle facet426may be parallel to girdle line of previous secondary upper girdle facet426for double girdle line effect. The middle point of this secondary upper girdle facet426reaches approximately 60% up primary upper girdle facet424. If triple girdle line is desired, the middle point may reach 45% to the primary upper girdle facet424and the procedure of previous secondary upper girdle facet426may be repeated. It begins at the middle point of secondary upper girdle facet426and may be cut flatter than secondary upper girdle facet426keeping spacing of three horizontal lines equal. The middle point of this secondary upper girdle facet426reaches about 60% up towards the primary upper girdle facet424. Referring toFIG. 6H, the finished secondary upper girdle facet426is shown.

Referring toFIG. 6I, using the same procedure as secondary upper girdle facet426ofFIG. 6Ethe inception of this secondary upper girdle facet426is on the right point of second primary upper girdle facet424. This secondary upper girdle facet426may be cut from higher and to the right of the second primary upper girdle facet424. The cut may be as high as practically possible so that the middle point of this secondary upper girdle facet426may not advance more than 30% up towards the second primary upper girdle facet426. The right point of this secondary upper girdle facet426reaches 20% past center of bezel402(indicated by arrow). The left point reaches towards the rib line between two primary upper girdle facets424(indicated by arrow) forming very small vertical rib line, formed when secondary upper girdle facet426ofFIG. 6Ibumps into secondary upper girdle facet426ofFIG. 6E. Referring toFIG. 6J, the finished secondary upper girdle facet426ofFIG. 6Iis shown.

Referring toFIG. 6K, secondary upper girdle facet426may be cut following the same procedure as the secondary upper girdle facet426ofFIG. 6Gwith the same option for triple lines. Referring toFIG. 6L, the finished secondary upper girdle facet426ofFIG. 6Kis shown. The two narrow rectangular horizontal upper girdle facets adjacent to the girdle may be past the centers of the bezels402. When upper girdle facet sets on the right and left are completed, the right and left points of finished upper girdle facet sets are “bumped” back to the centers of bezels402forming a very small vertical rib line at the center of each bezel402(indicated by arrow). In another embodiment the two narrow rectangular horizontal secondary upper girdle facets may be just to the centers of bezels402. Hence there would be no “bumps” between upper girdle facet sets.

Referring toFIG. 7A, inception of primary lower girdle facet430is shown. The starting point is the point where two girdle lines meet or intersect one rib line between two pavilions310. The primary lower girdle facet430may be cut directly between two pavilions310approximately 1° higher and approximately 12° to left of pavilion on the right side and 12° to right of pavilion310on the left side. Left and right points may reach approximately 60% to center of pavilion310(indicated by arrows). There are two middle points. The middle point advancing the rib line toward the culet312may reach 90% to the culet412. The other middle point directly below (indicated by an arrow) advances as deep into the girdle306at least identical to the middle point of pavilion310. Eventually, when a line is formed between those two points; that line will be parallel to the table408and the other horizontal lines formed by the upper girdle facet426above. In diagrams onFIGS. 7A-7Jthat latter middle point on primary lower girdle facet430advances into the girdle deeper than the middle point of pavilion310, thus forming a rib line slightly unparallel to the horizontal lines above (seeFIG. 5F). This may take off slightly more weight, but may add slightly more life to the stone. Referring toFIG. 7B, the finished primary lower girdle facet430ofFIG. 7Ais shown.

Referring toFIG. 7C, the inception of this secondary lower girdle facet432is on the left point of primary lower girdle facet430. It cuts from left and a bit higher than primary lower girdle facet430. The left point reaches about 50% of the remaining girdle line (halfway between left point of primary lower girdle facet430and center of pavilion (indicated by arrow)). The right point reaches the center of primary lower girdle facet430(indicated by arrow) and advances to culet412reaching about 90% to point of primary lower girdle facet430which is 10% from the culet412. Referring to FIG.7D, the finished secondary lower girdle facet432ofFIG. 7Cis shown.

Referring toFIG. 7E, inception of this secondary lower girdle facet432is on the left point of previous secondary lower girdle facet432. The previous procedure may be repeated. It cuts from left and a bit higher onto the previous secondary lower girdle facet432. The left point reaches towards the center of pavilion310(indicated by arrow). The right point reaches the center of primary lower girdle facet430(indicated by arrow), together with right rib line of previous secondary lower girdle facet432. The middle point advancing to culet412reaches approximately 80% to point of previous secondary lower girdle facet432which reaches approximately 90% to point of primary lower girdle facet430which is 10% from culet412. (this previous procedure may be repeated providing left rib line ofFIG. 7Edoes not reach center of pavilion310). Referring toFIG. 7F, the finished secondary lower girdle facet432ofFIG. 7Eis shown. The procedures ofFIGS. 6E-6G, which results in double girdle line may be applied after primary lower girdle facet430ofFIGS. 7A and 7Bbefore cutting the secondary girdle facets which would result in double line on bottom.

Referring toFIG. 7G, inception of this secondary lower girdle facet432is on the right point of primary lower girdle facet430. It may be cut from right and a bit higher than the primary lower girdle facet430. The right point reaches approximately 50% of the remaining girdle line (halfway between right point of primary lower girdle facet430and center of pavilion310(indicated by arrow). The left point reaches center of primary lower girdle facet430(indicated by arrow) together with two rib lines of previous two secondary lower girdle facets, and point advancing to culet412reaches 90% to point of primary lower girdle facet430which is 10% from culet412. Referring toFIG. 7H, the finished secondary lower girdle facet432ofFIG. 7Gis shown.

Referring toFIG. 7I, inception of this secondary lower girdle facet432is on the right point of previous secondary lower girdle facet432and previous procedure is repeated. It cuts from right and a bit higher onto previous secondary lower girdle facet432. The right point reaches to the center of pavilion (indicated by arrow). The left point reaches to the center of primary lower girdle facet430(indicated by arrow) together with two rib lines of previous three secondary lower girdle facets. The point advancing to culet412reaches approximately 80% of previous secondary lower girdle facet432which reaches approximately 90% to point of primary girdle facet430which is 10% from culet412. It is possible to repeat this procedure numerous times as was explained in directions to diagramFIG. 7Eproviding rib lines ofFIGS. 7E and 7Ido not reach center of pavilion. The less blocking facets on the diamond, the more times the procedure can be repeated on the diamond. The procedures ofFIGS. 6I-6K, which results in double girdle line, may be applied after the primary girdle facet430ofFIGS. 7A and 7Bbefore cutting the secondary girdle facets which would result in double girdle line on bottom.FIGS. 7C and 7Gmay reach centers of their respective pavilions eliminatingFIGS. 7E and 7I. In this case the lower girdle facet set would comprise one primary lower girdle facet and two secondary lower girdle facets. Referring toFIG. 7J, the finished secondary facet ofFIG. 7I432is shown.

The inception of this Secondary Lower Girdle Facet (S.L.G.F.) may be on left point of primary lower girdle facet. It cuts from left and a bit higher than primary lower girdle facet. Left point reaches center of pavilion on left. Right point reaches center of primary lower girdle facet, and middle point advancing toward culet may reach approx. 85% to middle point of primary lower girdle facet which may reach approx. 95% to culet. The inception of this S.L.G.F. is on right point of P.L.G.F. It cuts from right and a bit higher than P.L.G.F. Right point reaches center of pavilion on right. Left point reaches right point of previous S.L.G.F. at center of P.L.G.F., and middle point advancing toward culet may reach approximately 85% to middle point of P.L.G.F. identically to S.L.G.F. on left. In another embodiment of a lower girdle facet set the first secondary lower girdle facet may be cut as high as practically possible identically to secondary upper girdle facet. The inception of this Secondary Lower Girdle Facet (S.L.G.F.) may be on left point of Primary Lower Girdle Facet (P.L.G.F.). This S.L.G.F. may be cut as high as practically possible so that middle point advances up left rib line of Primary Lower Girdle Facet as minimum as possible. Left point of this S.L.G.F. may reach from 10 to 20% past center of pavilion on left (indicated by arrow), and right point may reach from 10 to 20% past center of P.L.G.F. (indicated by arrow).

Inception of this Secondary Lower Girdle Facet may be on middle point of previous S.L.G.F. It is cut from flatter than previous S.L.G.F. Left point reaches center of pavilion on left. Right point reaches center of P.L.G.F. The horizontal rib line formed between right and left points of this S.L.G.F. may be parallel to girdle line of previous S.L.G.F. giving double girdle line effect. Middle point of this S.L.G.F. may reach approximately 85% to middle point of P.L.G.F. which may reach approximately 95% to culet. This Secondary Lower Girdle Facet may be cut identically to first S.L.G.F. of this embodiment except that inception of this S.L.G.F. is on right point of P.L.G.F., right point reaches 10 to 20% past center of pavilion on right and left point reaches center of P.L.G.F. forming small vertical rib line as present Secondary Lower Girdle Facet (e) bumps into S.L.G.F. (a) of this embodiment (f) finished S.L.G.F. Inception of this S.L.G.F. is on middle point of previous S.L.G.F. It is cut from flatter than previous S.L.G.F. Right point reaches center of pavilion on right. Left point reaches right point of finished S.L.G.F. (d) at center of P.L.G.F. The horizontal formed between left and right points of this S.L.G.F. may be parallel to girdle line of previous S.L.G.F. giving double girdle line effect. Middle point of this S.L.G.F. advancing toward culet may reach approximately 85% to middle point of P.L.G.F. identically to finished S.L.G.F. on left. The two narrow horizontal Secondary Lower Girdle Facets of lower girdle facet set off the girdle are past the centers of their respective pavilion or right and left. When lower girdle facets on right and left are completed the right and left points of previously completed lower girdle facet set are bumped back to centers of pavilions on right and left forming a small vertical rib line at centers of the pavilions.

A third exemplary embodiment of a blocked stone may be an exemplary gemstone cut from a rough diamond with the crown having a table surrounded by six star sets. The six star sets may be surrounded by six bezel facets each bent away 60° from the adjacent bezel unlike the exemplary gemstone that may be cut from a round stone which has eight bezels each bent away 45° from the adjacent bezel. The six bezel facets may be surrounded by six pairs of upper girdle facet sets each set consisting of two primary girdle facets and just two secondary girdle facets (in this embodiment there are no narrow rectangular secondary upper girdle facets). In this embodiment each star set has one primary star and four secondary stars like the previous exemplary gemstone of 8 bezels and 8 pavilions (8 counts) cut from a round stone, but unlike that stone the primary star on this new embodiment may also be referred to as a secondary bezel facet. This being since normally star facets do not reach girdle just as upper girdle facets do not reach table, i.e., brilliandeering facets do not reach from table to girdle. Being that in the initial forming of the “primary star facet” in this new embodiment this facet reaches into the table and into the girdle as shown1108, this facet may be referred to a secondary bezel. The four secondary star facets of each star set in this embodiment may be cut identically to the four secondary facets of the previous 8 count exemplary gemstone that may be cut from a round stone, two of those secondary star facets being narrow rectangular facets. In this embodiment the bottom is identical to the bottom of the previous 8 count gemstone that may be cut from the round stone except that instead of eight pavilions each bent away from the adjacent pavilions 45° there are six pavilions each bent away from the adjacent pavilion 60°. Like the exemplary gemstone of 8 count that may be cut from the round stone these six pavilions are line up directly underneath the six bezels and the lower bottom girdle facet sets are identical to the lower girdle facet sets on the previous exemplary gemstone of 8 count that may be cut from the round stone except on this new embodiment they may reach nearer to culet and may have added secondary lower girdle facets being that there is less blocking as discussed. In this embodiment there may be 12 narrow rectangular girdle facets adjacent parallel and lined up with the twelve narrow triangular secondary upper girdle facets. Each girdle facet equally bent away from the other creating a circle of narrow rectangular girdle facets each bent away 30° from the next as shown inFIG. 13. Finally in this embodiment the twelve narrow rectangular secondary star facets (or the 24 narrow rectangular secondary star facets if the triple table line is in effect) may be parallel and lined up with the twelve girdle facets thus creating a smaller inner circle of table lines each bent away from the next 30° as shown inFIG. 13parallel and lined up with the larger outer circle of girdle lines.

In another embodiment there may be a triple table line effect by adding one narrow rectangular secondary star facet directly underneath lining up and parallel to each of the two narrow rectangular secondary star facets as a result creating a total of six secondary star facets in each of the six star sets identical to the previous exemplary gemstone from the round stone with eight star sets.

In another embodiment the narrow rectangular secondary star facets “bump” into narrow rectangular secondary star facets of adjacent star sets at the center of bezels, identically to narrow rectangular secondary star facets on the exemplary gemstone of 8 count that may be cut from a round stone, but unlike that latter gemstone, the two narrow rectangular secondary star facets in a star set just touch, but do not “bump” into each other at the center of the primary star facet, as shown inFIG. 13. (This allows slightly more white light in star sets and in table).

Referring toFIG. 16A, inception of the primary star facet1308or in a third embodiment which may also be referred as secondary bezel facet1108as explained above regarding S.L.G.F. and P.L.G.F., the starting point is where two table lines meet one rib line. SeeFIG. 10. The starting point of this primary star facet1308is cut directly between two bezels1102approximately 3 or 4 degrees flatter then bezels1102. Although the starting point of this primary star facet1308is where two table lines meet one rib line this facet cut onto all the points of that rib line almost simultaneously. If this facet would cut onto all the points of that rib line simultaneously the two new rib lines on right and left of the previous rib line would be parallel to each other and the new facet forming between them would not be wider above than below or visa versa, but being that this primary star facet1308does begin on above point of aforesaid rib line (between two bezels1102) slightly before all the below points on that rib line the two new rib lines are slightly unparallel and the new facet formed between them is slightly wider above than below. Being that this facet is ever so slightly wider above than below, even though the starting point is above, between the two table lines of the bezels, this primary star facet1308advances ever so quickly to the girdle and the two points on the girdle lines begin their advance toward the center of their respective girdle facets (indicated by arrows) ever so slightly after the two points above begin their advance toward the center of their respective table lines (indicated by arrows). This primary star facet1308(or secondary bezel facet1108) is finished when two points above reach approximately ¾ to the center of their respective table lines (indicated by arrows) and the two points below reach approximately halfway to the center of their respective girdle facets (indicated by arrows).

Referring toFIG. 16C, see the discussion above regardingFIGS. 5A and 5B. Cut may be identical except that right point may reach just to the center of the primary star facet1308. Referring toFIG. 16D, the finished secondary star facet1310ofFIG. 16Cis shown.

Referring toFIG. 17E, see the discussion above regardingFIGS. 5C and 5D. Referring toFIG. 17Fa finished secondary star facet1310ofFIG. 17Eis shown. The secondary star facet may be cut as flat as practically possible so that the middle point reaches as minimum as possible toward the girdle, allowing more light in the table.

Referring toFIG. 17G, see the discussion above regardingFIGS. 5E and 5F. Cut may be an identical cut except that the left point reaches just to the center of the primary star facet1308eliminating a bump at the center of the primary star facet1308allowing more white light in the star sets and in the table as discussed above regarding S.L.G.F. Referring toFIG. 17Ha finished secondary star facet1310ofFIG. 17Gis shown.

Referring toFIG. 18I, see the discussion above regardingFIG. 5G. Referring toFIG. 18Ja finished secondary star facet1310ofFIG. 18Iis shown. See also the discussion above regardingFIGS. 16C and 16D. Another embodiment may be the star sets as having no narrow rectangular secondary star facets above triangular secondary star facets leaving a star set with one primary star facet and just two secondary star facets eliminating the double table line effect.

Referring toFIG. 19Athe inception of a first primary upper girdle facet1312is shown. The starting point of this primary upper girdle facet1312may be the left rib line of the primary star facet1308(or secondary bezel facet1108) where the girdle line of that latter facet meets the girdle line of the bezel on left. This facet may be cut from left and higher of primary star facet1308. This primary upper girdle facet1312begins as a triangle at inception and ends as a polygon (four sided and no parallel lines). The right point of the triangle formed at inception reaches center of the primary star facet1308(indicated by arrow) then develops into a rib line (hence developing from triangle to polygon) as the facet progresses. The right point of this newly developed aforesaid rib line may reach almost to or actually to the right rib line of the primary star facet1308or secondary bezel1108, and the left point of this same newly developed rib line advances ever so slightly into girdle at the center of the primary star facet1308(indicated by arrow). See the discussion above regardingFIGS. 5A to 5Jabout this middle point and middle point of bezel. The middle point of the triangle formed at inception (now a polygon) advances up the rib line of primary star facet1308anywhere from approximately 70% toward the above secondary star facet to actually touching the above secondary star facet. The left point of the triangle formed at inception (now a polygon) may reach 65% to center of bezel on left (indicated by arrow) referring toFIG. 19Bthe finished primary upper girdle facet1312ofFIG. 19Ais shown.

Referring toFIG. 19Cthe inception of a second primary upper girdle facet1312. The starting point is on right rib line of the primary star facet1308or secondary bezel facet1108where girdle line of that latter facet meets girdle line of bezel on right. This facet may be cut from right and higher of primary star facet1308. This second primary girdle facet1312may begin as a triangle at inception immediately developing into a polygon as left point “bumps” into right point of first primary girdle facet1312hence that left point developed into rib line. This latter rib line may be a vertical rib line. This vertical rib line advances to the left into first primary upper girdle facet1312and may reach up to center of primary star facet1308(indicated by arrow). The middle point of this second primary upper girdle facet1312advances up the rib line of primary star facet1308anywhere from approximately 70% toward the above secondary star facet1310to actually touching the above secondary star facet1310. The right point of this second primary upper girdle facet1312may reach 65% to center of bezel1302on right (indicated by arrow). Referring toFIG. 19D, the finished primary upper girdle facet1312ofFIG. 19Cis shown.

Referring toFIG. 20Ethe inception of a secondary upper girdle facet1314is shown. The starting point is on left point of left primary upper girdle facet1312. This facet may be cut from higher and a bit left of primary upper girdle facet1312. This secondary upper girdle facet1314may be cut as high as practically possible so that the middle point advances up left rib line of left primary upper girdle facet1312as minimum as possible. The right point may reach up to the vertical rib line between two primary girdle facets1312at center of primary star facet1308at right end of girdle facet1304(indicated by arrow). The left point of this secondary upper girdle facet1314may reach up to center of bezel1302on left at left end of girdle facet1304(indicated by arrow). Referring toFIG. 20F, the finished secondary upper girdle facet1314ofFIG. 20Eis shown.

Referring toFIG. 20Gthe inception of the other secondary upper girdle facet1314is shown. It is cut identically to the first ofFIGS. 19C and 19Dabove. Being thatFIG. 20Gis on right, this facet may be cut from higher and a bit right of primary upper girdle facet1312and the right point may reach center of bezel1302on right at the right end of the girdle facet1304and left point may reach vertical rib line at center of primary star facet1308between the two primary girdle facets1312at left end of girdle facet1304. Referring toFIG. 20H, the finished secondary upper girdle facet1314ofFIG. 20Gis shown.

This style of girdle faceting and brilliandeering may be applied to any cut or shape when appropriate as one skilled in the art would appreciate. From 8 count (8 bezels and 8 pavilions)FIGS. 3A-3Ceach bezel and pavilion cut 45° away from its adjacent bezel and pavilion and 16 girdle facets each cut 22½° away from its adjacent girdle facet (seeFIG. 1to understand term “cut away”); the 16 girdle facets forming a very slightly modified circle, to 7 count (7 bezels and 7 pavilions) each bent away from its adjacent one 51.428° and 14 girdle facets (2 of each bezel and pavilion lined up underneath) each of the 14 cut 25.714° away from each other forming a slightly more modified circle; to 6 countFIG. 8,FIG. 10, andFIG. 12each bezel and pavilion cut 60° away from each other and 12 girdle facets each cut 30° away from each other forming a slightly more modified circle; to 5 count resulting with each bezel and pavilion cut 72° away from each other and 10 girdle facets each cut 36° away from each other forming a slightly more modified circle; to 4 count resulting with each bezel and pavilion cut 90° away from each other and 8 girdle facets each cut 45° away from each other forming an octagon shape; to 3 count resulting with each bezel and pavilion cut 120° away from each other and 6 girdle facets each cut 60° away from each other forming a hexagon shape; these 6 exemplary blocking methods may be blocked with identical guide lines disclosed herein, i.e., bezels may be between 30° and 36° to girdle; pavilions directly underneath bezels may be between 40° and 42° to the girdle; bezels and pavilions may be cut equal amount of degrees away from each other; 2 girdle facets to each bezel and pavilion lined up underneath; and each girdle facet may be cut an equal amount of degrees away from each other. The only guide line that may change in the blocking of these 6 exemplary blocking methods is the table size. The ideal table size of the exemplary blocking method of8is 57% ranging from 59% to 55%; as the blocking count gets less, the table size may be smaller. In these 6 exemplary blocking methods the top may be brilliandeered with primary star facet as secondary bezel1108. SeeFIG. 11,FIG. 13, andFIGS. 16A-20H. The bottom may be brilliandeered as discussed above regardingFIGS. 7A-7J. As blocking count becomes less, procedures ofFIGS. 7E and 7Imay be repeated more times (seeFIG. 15) providing that previous secondary lower girdle facets are kept away from centers of pavilions. See the discussion above regardingFIGS. 7G and 7H. Being that these 6 exemplary blocking methods are perfectly symmetrical, i.e., all bezels and pavilions are identical in measurement and cut an equal amount of degrees away from each other, resulting in diamonds that are not long, the symmetry of the primary and secondary brilliandeering facets may be perfect, i.e., the primary star facets1308(or secondary bezels1108) and primary lower girdle facets430may all be identical in measurements and these primary star facets1308may be cut directly between 2 bezels cutting equally into bezels on right and left. Likewise these primary lower girdle facets430may be cut directly between 2 pavilions cutting equally into pavilions on right and left. Likewise the pair of primary upper girdle facets1312may be identical in measurements, being that the bezels on right and left are same in length the primary upper girdle facets may also be the same in length and likewise the secondary upper girdle facets may be identical in measurements, i.e., the secondary upper girdle facets1314on right and left may be identical in length; and likewise the secondary star facets1310on right and left may be identical in length and likewise the secondary lower girdle facets432on right and left may be identical in width. In another embodiment of the 4 count resulting with each bezel and pavilion directly underneath cut 90° away from each other, the 8 girdle facets do not have to all be equally cut away from each other by 45° resulting in an octagon shape. This embodiment may have each of the 2 girdle facets on the 4 bezels and pavilions lined up underneath as a pair of girdle facets with each girdle facet of the pair cut 22½° away from each other and hence each pair of girdle facets would be cut 67½° away from the adjacent pair resulting in a modified square shape (a square shape in the diamond industry being a princess cut). Just by adding 4 very small girdle facets, one very small girdle facet on each point between the 4 pairs of girdle facets (the 4 sharp points of the modified square) may result in a cushion. Top is brilliandeered as shown inFIGS. 16A-20Hand bottom as shown inFIGS. 7A-7J. In another embodiment of the 4 count resulting with each bezel and pavilion directly underneath cut 90° away from each other, 2 of the 4 bezels which are parallel to each other may be substantially longer that the 2nd2 bezels to which they are perpendicular, resulting in a rectangular shape. In this embodiment the symmetry can not be perfect. The 2 girdle facets on the longer bezels will be longer than the 2 girdle facets on the shorter bezels and hence the pair of girdle facets on the longer bezels will be cut away from each other slightly less degrees less than the pair of girdle facets on the shorter bezels in order for the pairs of girdle facets to line up with each other (to understand what is meant by the phrase “pairs of girdle facets to line up with each other” seeFIG. 3Aand/orFIG. 8and note how girdle lines of girdle facets line up with each other, meaning they touch each other). Hence the pair of girdle facets on the shorter bezels may be cut 25° away from each other and the pair of girdle facets on the longer bezels may be cut 20° away from each other hence the 4 pairs of girdle facets may be cut 67½° away from each other forming a modified rectangular shape (a rectangular shape in the diamond industry being a radiant cut). Another reason why in this embodiment the symmetry can not be perfect is, being the bezels 90° and adjacent to each other are not of equal length the primary star facets1308(or secondary bezels1108) and primary lower girdle facets430may all be identical in measurements, but may not be cut directly between bezels and directly between pavilions being that the bezel on the right of one primary star facet1308may be longer than the bezel on the left of this primary star facet1308and the primary star facet must approach the center of the bezel on the right; the same as it would approach the center of the bezel on the left; this primary star facet would not be cut directly between the 2 bezels cutting equally into the 2 bezels. This primary star facet would be cutting further, a greater distance, into the right bezel than into the left, being that the center of the bezel on right is further from starting point of primary star facet1308(indicated by arrow, seeFIG. 16A) than the center of bezel on left, and being that from center of bezel on right is the greater distance back to the starting point of primary star facet1308, and the secondary star facet1310on right must reach from center on right to that point (seeFIGS. 16A-16J) then the secondary star facet1310on right. Likewise being that the pavilion on the right of one primary lower girdle facet430may be wider than the pavilion on the left of this primary lower girdle facet430and the primary lower girdle facet430must approach the center of the pavilion on the right; the same as it would approach the center of the pavilion on the left; this primary lower girdle facet430would not be cut directly between the 2 pavilions cutting equally into the 2 pavilions. This primary lower girdle facet430would be cutting further, a greater distance, into the right pavilion than into the left, being that the center of the pavilion on right is further from starting point of primary lower girdle facet430(indicated by arrow seeFIG. 7A), than center of pavilion on left, and bring that from center of pavilion on right is the greater distance back to the starting point of primary lower girdle facet430, and the secondary lower girdle facets432on right must reach from center on right to that point, SeeFIGS. 7A-7J. The secondary lower girdle facets (or facet)432on right will automatically be wider than the secondary lower girdle facet432on left. Concerning the pair of primary upper girdle facets1312underneath the aforementioned primary star facet1308and secondary star facets1310, the primary upper girdle facet1312on right of pair would simply be longer than the primary upper girdle facet1312on left. SeeFIGS. 19A-19D, where the secondary upper girdle facet1314on right would be longer than the secondary upper girdle facet1314on left. SeeFIGS. 20E-20H. In another embodiment of 4 counts all bezels and pavilions may be identical in measurements but not 90° to each other. In this embodiment there may be 2 obtuse angles opposite each other and 2 acute angles opposite each other; accordingly where the pairs of girdle facets meet by the 2 acute angles there will be very acute angles between the 2 girdle facets. By all the other 6 places where girdle facets meet they may be equally slightly cut away from each other forming a marquise shape. The primary star facets1308opposite each other where the bezels form obtuse angles may be much longer than the primary star facets1308where the bezels form acute angles the rest of the brilliandeering on top may set in following the FIGS. of16C-20H and the guidelines discussed above. In summary, secondary brilliandeering is setting in facets by connecting points from one end of the girdle facet on left to the other end of that same girdle facet on the right of the secondary brilliandeering's starting point which is always on the point of a rib line of its primary brilliandeering facet. SeeFIGS. 16B-18JandFIGS. 20E-20H. For primary upper girdle faceting seeFIGS. 19A-19D, and for bottom brilliandeering seeFIGS. 7A-7J. Another embodiment may be a pear shape in which half of the diamond would be blocked and girdle faceted as half of the exemplary round stone of 8 count cut from a round stone, consisting of 4 bezels and 4 pavilions underneath with 8 girdle facets cut into a semicircle and the other half blocked and girdle faceted as half of the marquise discussed just above with 2 long bezels and 2 wide pavilions and two pair of girdle facets form the point of the pear shape where 2 girdle facets meet at an acute angle. The primary and secondary brilliandeering on the top may be cut as shown inFIGS. 16A-20Hand the guidelines discussed above. The bottoms of both the marquise and pear shape may be brilliandeered as discussed in directions to lower girdle sets, and guidelines discussed above. In another embodiment the 3 count may be blocked into an isosceles triangle with 3 bezel and 3 pavilions directly underneath cut 120° away from each other forming 60° angles to each other but instead of all 6 girdle facets cut 60° away equally from each other to form a perfect hexagon the pairs of girdle facets may be cut 90° from each other and the 2 girdle facets of each pair of girdle facets cut 30° away from each other forming a modified triangle (triangle shaped diamonds are known as trilliants). This embodiment may be brilliandeered as shown inFIGS. 16A-20Hfor top andFIGS. 7A-7Jfor bottom. By cutting a groove in the middle of one of the sides of the triangle and rounding off the 2 points on right and left of that groove leaving the point opposite the groove sharp, a heart shape may be formed. The 8-5 count cuts may be elongated to form the oval shapes as shown inFIGS. 21A-21C,FIGS. 22A-22C, andFIGS. 24A-24C. Primary and secondary brilliandeering may be practiced on a perfectly round stone.
