BACKGROUND OF THE INVENTION 
The invention relates to jewelry with set gemstones and/or beads. 
There exist a plurality of different kinds of jewelry such as rings, ear 
rings, brooches, bracelets, diadems or the like, in which gemstones and/or 
beads are set. The production of such jewelry is in general time-consuming 
and requires above all, especially if a number of gemstones and/or beads 
are to be set in a single piece of jewelry, an especially time-consuming 
single production of the respective piece of jewelry, so that not only the 
material costs but also the actual production costs are high. 
The object of the present invention is to provide in particular jewelry 
with set gemstones and/or beads, whose production costs for various 
possible choices and variations with respect to the gemstones and/or beads 
that are used are relatively low and that can, nevertheless, be produced 
in the most precious embodiments down to inexpensive, but also quite 
aesthetic embodiments. 
SUMMARY OF A PREFERRED EMBODIMENT OF THE INVENTION 
This problem is solved, according to the invention, by means of a piece of 
jewelry that comprises the following: 
a) a first section of jewelry exhibiting receiving openings for the loose 
setting of gemstones or beads; and 
b) a second section of jewelry, which can be mounted detachably on the 
first section of jewelry and exhibits viewing openings, 
where the receiving openings of the first section of jewelry and the 
viewing openings of the second section of jewelry are designed in such a 
manner that in the assembled state of the jewelry sections, in which the 
second section of jewelry is mounted detachably on the first section of 
jewelry, 
(1) gemstones or beads set into the receiving openings of the first section 
of jewelry are visible through the viewing openings of the second section 
of the piece of jewelry; and 
(2) at least one portion of the border of the viewing openings of the 
second section of the piece of jewelry rests on one of the gemstones or 
one of the beads and holds said gemstone or bead in the respective 
receiving opening in the first section of the piece of jewelry, 
where 
(A) all or a portion of the borders of the viewing openings are designed as 
a lattice-shaped jewelry pattern; and 
(B) for one and same piece of jewelry 
(1) either all or a portion of the borders of the viewing openings rest by 
choice on side edges of the gemstones or beads located directly 
underneath, 
(2) or all or a portion of the webs of the lattice-shaped jewelry pattern, 
which is located between the laterally adjacent viewing openings, rest by 
choice on the central regions of the gemstones or beads located directly 
underneath. 
The latter kind of relative configuration between borders and gemstones 
and/or beads can be aesthetically very attractive, especially for 
gemstones. 
Such jewelry can be produced--and that applies not only to the above basic 
embodiment but also to the other engineered embodiments listed below--in 
such a manner that the actual production costs, i.e. thus without any 
consideration of the material costs, are relatively low, because, for 
example, the aforementioned jewelry is produced on computer-controlled 
material processing machines, where the assembly costs for joining jewelry 
sections and gemstones and/or beads, are relatively low compared to the 
conventional jewelry of suitable scope. Nevertheless, a number of 
different pieces of jewelry can be produced with the same jewelry sections 
by selecting different configurations and kinds of gemstones and/or beads 
and different combinations of different kinds of gemstones and/or beads. 
Even the same geometrical shape of the aforementioned jewelry sections 
themselves can be designed with different materials, e.g. precious metals 
or precious metal alloys, but also from non-precious metals or alloys, 
which are preferably gold-plated or silver-plated or platinum-plated. 
Another improvement of the aforementioned basic embodiment of the jewelry 
according to the invention, with which even more diverse shapes of jewelry 
can be obtained, is characterized in that 
(a) the second jewelry section exhibits, besides viewing openings, 
receiving openings for the loose setting of additional gemstones or beads; 
and 
(b) a third jewelry section is provided that can be mounted detachably on 
the second jewelry section and that exhibits viewing openings; 
where in the assembled state, in which the third jewelry section is mounted 
detachably on the second jewelry section, 
(1) gemstones or beads set into the receiving openings of the second 
jewelry section are visible through the viewing openings of the third 
jewelry section; 
(2) at least one portion of the border of the viewing openings of the third 
jewelry section rests on one of the additional gemstones or one of the 
additional beads and holds said gemstone or bead in the respective 
receiving opening; 
and where in the detachably assembled state of all of the jewelry sections 
the third jewelry section allows the viewing openings of the first jewelry 
section to remain exposed on the outside. 
This embodiment makes it possible to design jewelry with at least two 
different regions set with gemstones and/or beads, thus resulting in a 
larger diversity of possible configurations and designs. 
Virtually any engineered shape of jewelry can be obtained from the almost 
unlimited diversity of configurations and designs with an improvement of 
the jewelry, which exhibits the invention and builds on the latter 
embodiment of the invention and which is characterized in that several 
jewelry sections, each of which exhibits both receiving openings for the 
loose setting of additional gemstones or beads and also viewing openings, 
are stacked between the first and third jewelry section; where the first 
jewelry section, the second jewelry sections and the third jewelry section 
can be connected together detachably; and in the assembled state of the 
jewelry sections, in which the first jewelry section, the second jewelry 
sections and the third jewelry section are connected together detachably, 
(a) the gemstones or beads set into the receiving openings of each of the 
jewelry sections are visible through the viewing openings of the jewelry 
section, mounted, in particular directly, above; 
(b) at least one portion of the border of the viewing openings of each 
jewelry section provided with the same rests on one of the gemstones or 
one of the beads, which are set into the receiving openings of a jewelry 
section arranged directly underneath, and thus holds said gemstone or bead 
in the respective receiving opening; and 
(c) all viewing openings are visible from the outside. 
This embodiment of the invention makes it possible to obtain jewelry with 
any desired number of identically or differently shaped jewelry regions 
with gemstone and/or bead settings, whereby the number of jewelry regions 
is limited in essence only by the space available for the respective 
jewelry, and whereby within the space that the jewelry occupies the 
maximum density of gemstones and/or beads can be concentrated in a manner 
that is aesthetically highly attractive. 
For maximum and optimal utilization of the space available for the jewelry 
with respect to the embodiment of the jewelry according to the invention, 
in which more than two jewelry sections of the aforementioned kind are 
stacked and connected detachably together, the jewelry according to the 
invention can be designed in such a manner in these cases that some or all 
receiving openings are passage openings, and that there are free space 
openings in the regions of the jewelry sections, which are situated in the 
assembled state of the jewelry directly below such a passage opening; and 
that the rear sides of the gemstones or beads held in these passage 
openings are arranged so as to be exposed above or in said free space 
openings, so that the said jewelry sections can be made thin and stacked 
densely, without hindering this design on account of a thickness of the 
gemstones that is necessary for reasons relating to the polishing. 
Thus a higher and aesthetically more efficient concentration of the 
gemstones and beads than that of the invention is hardly conceivable. 
Such a concentration and high efficiency of gemstones and/or beads is also 
made possible in that according to the invention all or a portion of the 
borders of the viewing openings are designed as a lattice-shaped jewelry 
pattern, so that adjacent gemstones and/or beads are separated for the 
observer only by means of webs of the lattice-shaped jewelry pattern, 
which can be designed very thin. 
A preferred embodiment of the invention is characterized in that the 
individiual jewelry sections are designed as concave parts, whose 
concavity faces the interior of the piece of jewelry, whereby it is 
especially preferred that the individual jewelry sections are designed 
into concave shells, which can be both rounded, such as spherical shells 
or calottes and ellipsoid shells or calottes, and rectangular or 
rounded-rectangular, such as square shells, and can also exhibit rounded 
and/or rectangular and/or flat regions. 
In so doing, it is especially preferred that the concavity of the jewelry 
sections and the size and configuration of the gemstones or beads be 
coordinated in such a manner that no gemstones project beyond the actual 
basal plane of the jewelry, i.e. beyond the rear side of the piece of 
jewelry. 
One embodiment of the piece of jewelry that exhibits the invention and is 
especially interesting with respect to its shape and is suitable not only 
for jewelry along the line of a brooch is designed in such a manner that 
the individual jewelry sections designed as concave shells have the shape 
of conical or pyramidal disks, and in the assembled state form a conical, 
truncated, pyramidal, or truncated pyramidal piece of jewelry, whereby 
preferably the angle between the central axis of the cone or pyramid and 
the conical and pyramidal areas of the piece of jewelry is selected in 
such a manner in accordance with the size and configuration of the 
gemstones or beads that no gemstones or beads project outwardly beyond the 
actual basal plane of the piece of jewelry. 
To fasten together detachably the jewelry sections, various known 
detachable connections are suitable, so that here as only one example of 
such a detachable connection is cited a screw-nut connection, with which 
the jewelry sections can be fastened together. Such an element of the 
detachable connection that is visible to the observer of the assembled and 
worn jewelry, can be designed as a decorative element of the piece of 
jewelry, so that thus in the above example the screw and/or the nut of the 
screw-nut connection is designed at least partially as a decorative 
element of the jewelry. This decorative element is then designed 
preferably in such a manner that it forms for the observer an integral 
component of the entire piece of jewelry, in particular an uppermost 
element that is concave toward the interior of the jewelry, such as a 
concave shell, whose shape matches that of the other concave elements, 
thus e.g. a concave disk for a pyramidal piece of jewelry. 
The jewelry sections, provided with receiving openings and/or viewing 
openings, and also the aforementioned "decorative element" are preferably 
coated with precious metal or precious metal alloy or made wholly or 
partially of precious metal or precious metal alloy, even though basically 
various other materials can also be used, such as non-precious metals, 
ivory, ornamental wood, ceramic, in particular porcelain, real shell and 
other organic substances, simple and high-quality plastics or the like. 
Suitable gemstones are in particular precious stones, like diamond, 
saphire, emerald, tourmaline, hematite, jade and the like and also 
gemstones made of other minerals and other non-precious materials. The 
gemstones can also be made, however, of non-mineral materials such as 
amber, glass, ceramic or plastic. In addition, they do not have to be 
necessarily square, but can have different shapes and exhibit sharp and/or 
rounded edges and/or corners and also have facets. By "beads" are 
understood here not only oriental pearls, cultured pearls, shell beads and 
other beads made of mother-of-pearl or conventional jewelry beads, but all 
possible bead-shaped materials, like precious stone beads such as jade 
beads, hematite beads, coral beads, amber beads, ivory beads, metal beads, 
glass beads, ceramic beads, plastic beads, and the like. The beads do not 
have to be absolutely spherical, but can also have other rounded shapes, 
like tear-shaped, oval or the like. 
The invention with respect to the entire configuration of the piece of 
jewelry can be implemented in various ways, without thus limiting the 
basic idea, so that here only brooches, bracelets arm loops, head or hair 
jewelry, in particular diadems, rings, pendants, in particular pendants 
for necklaces or ear jewelry are cited that can be designed wholly or 
partially as jewelry articles according to the invention. 
Preferably the surface area of the individually stacked, aforementioned 
jewelry increases step-by-step, in particular the diameter increases 
step-by-step, as apparent from the other embodiments described below. 
It is evident from the above explanation that not only the jewelry articles 
of jewelry, which exhibits the invention and is made of identical jewelry 
sections, can be produced as a diversity of aesthetically similar and/or 
highly different jewelry articles by using different gemstones and/or 
beads and different configurations of the same in the individual sections, 
but one and the same jewelry article can be modified repeatedly by the 
user, following purchase, according to her taste for different occasions 
by offering additional different kinds of gemstones and/or beads.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION 
First of all, one embodiment of a piece of jewelry according to the 
invention is described in the following with reference to FIGS. 1 to 3 and 
5. 
The jewelry, which is depicted in the aforementioned figures and is denoted 
in its entirety as 1, comprises--apart from non-illustrated pin-on, 
connecting or other fastening elements for direct or indirect fastening of 
the same to clothing or the body of a wearer--the following major 
elements: 
(a) a first jewelry section 2, which has receiving openings 3, which are 
designed in such a manner in the present design that they are suitable for 
the loose setting of gemstones 4, of which, however, all or a portion can 
be designed in such a manner that they are suitable for holding beads, in 
which case they are designed preferably circular, instead of, as shown, 
rectangular, in particular trapezoid; 
(b) a second jewelry section 5, which is mounted detachably on the first 
jewelry section 2 and exhibits viewing openings 6, and has also receiving 
openings 7, which are designed in the present design for the loose setting 
of gemstones 8, but of which all or a portion can also be designed for the 
suitable holding of beads; 
(c) a third jewelry section 9, which is mounted detachably on the second 
jewelry section 5 and exhibits viewing openings 10; 
(d) a nut 11, which exhibits a hat 12, designed as a decorative, integral 
part of the jewelry article 1 and whose actual nut member 13 can be 
inserted through the central passage openings 14, 15, and 16 into the 
jewelry sections 2, 5, and 9; and 
(e) a screw 17, which also has a hat 18 and whose shaft 19 provided with an 
external thread can be screwed into the internal thread of the nut member 
13, so that in this manner the jewelry sections 2, 5 and 9 are fastened 
detachably, as shown in FIGS. 5 and 6. 
The receiving openings 3 of the first jewelry section I and the viewing 
openings 6 of the second jewelry section 5 and the receiving openings 7 of 
the second jewelry section 5 and the viewing openings 10 of the third 
jewelry section 9 are designed and arranged in such a manner that in the 
assembled state of the jewelry sections 2, 5 and 9, in which the same are 
fastened together detachably by means of the nut 11 and the screw 17 and 
one gemstone 4 or 8 is set loosely into each of the receiving openings 3 
and 7 (see in particular FIG. 5), 
(1) the gemstones 4, set loosely into the receiving openings 3 of the first 
jewelry section 2, are visible through the viewing openings 6 of the 
second jewelry section 5 and thus at least one portion of the border 31 
(by which can be understood only one portion of one of the four sides of 
the respective viewing opening or one web or the like protruding into said 
opening) of the viewing openings 6 of the second jewelry section 5 rests 
on one of the gemstones 4 and holds said stone in the respective receiving 
opening 3 in the first jewelry section 2; 
(2) gemstones 8, set loosely into the receiving openings 7 of the second 
jewelry section 5, are visible through the viewing openings 10 of the 
third jewelry section 9 and thus at least one portion of the border 20 (by 
which can also be understood only one portion of one of the four sections 
of the respective viewing opening or a web or the like projecting into 
said opening) of the viewing openings 10 of the third jewelry section 9 
rests on one of the gemstones 8 and holds it thus in the respective 
receiving opening 7 of the second jewelry section 5; and 
(3) all visible openings 6 and 10 are exposed externally, so that all 
gemstones 4 and 8 are visible to the observer. 
As FIGS. 1, 2 and 3 and 5 show, the first jewelry section 2, the second 
jewelry section 5 and the third jewelry section 9 and the externally 
visible hat 12 of the nut 11 are designed as pyramidal disks, which in the 
assembled state form a multistepped pyramidal piece of jewelry 1. The 
angle .varies. (see FIG. 5) between the pyramid center axis 21 and the 
pyramidal areas 22 of the jewelry article 1 can be selected over a wide 
range and is chosen preferably in such a manner that the rear sides of the 
gemstones 4 (or suitable beads), which lie the closest to the rear side of 
the gemstone (at the bottom in FIG. 5), do not project outwardly beyond 
the actual basal plane 30. 
As FIGS. 1, 2 and 3 also show, the receiving openings 3 and 7 and the 
corresponding viewing openings 6 and 10 are arranged in strip-shaped 
regions, which are concentric relative to the pyramid center axis 21, so 
that they fill in essence a truncated pyramid region that is concentric to 
the pyramid center axis 21. In addition, the first jewelry section 2 also 
exhibits the following: 
(A) an ornamental lattice 23, whose lattice openings 24 are designed 
similar to the receiving openings 3 and which continue externally the 
step-like pyramid formed by the jewelry sections 2, 5 and 9 and the hat 
12, in that the ornamental lattice 23 is in the present design an integral 
component of the pyramidal disk formed by the first jewelry section 2; and 
(B) free space openings 25, which are arranged radially inwardly from the 
receiving openings 3 and in the present design have the Purpose of saving 
material, a state that above all is important in those cases in which the 
jewelry sections are made of precious metal or precious metal alloy and in 
which the jewelry is to be made as lightweight as possible for reasons 
owing to comfortable wearability; these free space openings 25 can, 
however, also be arranged in such a manner that in the assembled state of 
the jewelry article 1 they are in essence coincidence with the receiving 
openings 7, so that the rear sides of the gemstones 8 can be held with 
play, when the gemstones 8 have a relatively large depth, in particular 
for reasons owing to a reflection optimizing polish of the same; and the 
jewelry sections are to be designed relatively thin and/or are to be 
stacked closely together. 
As aforementioned, FIGS. 4 and 6 show another embodiment of the jewelry 
article 1, which is depicted in FIGS. 1, 3 and 5 and in which the jewelry 
sections 2, 5 and 9 are rotated with respect to each other in such a 
manner and fastened detachably together that 
(A) the webs 27 between the adjacent viewing openings 6 of the second 
jewelry section 5 extend over the central regions of the gemstones 4 
located in the receiving openings 3 of the first jewelry section 2; and 
(B) the webs 28 between the adjacent viewing openings 10 of the third 
jewelry section 9 extend over the central regions of the gemstones 8 
located in the receiving openings 7 of the second jewelry section 5. 
The result is thus, as the top view of FIG. 4 shows, an attractive 
aesthetic shape of the jewelry article, by means of which the webs 27 and 
28 are especially emphasized. 
It must be pointed out here that a third embodiment (not illustrated) can 
be formed here from the identical individual sections by suitable rotation 
in that only either the webs 27 or the webs 28 extend over the central 
regions of the assigned gemstones 4 or 8, whereas the remaining portion of 
this jewelry article corresponds to the embodiment of the jewelry article 
1 in FIGS. 1, 3 and 5. 
Even though in the above embodiment exclusively gemstones are set into the 
receiving openings, the above description applies correspondingly to the 
case that all gemstones or a portion of the gemstones are replaced by 
beads, in which case the receiving openings are designed, as 
aforementioned, round, instead of rectangular, and in which case the 
sloped seatings 29, which are provided in the receiving openings 3 and 7 
and intended for the gemstones 4 and 8, are replaced preferably by means 
of seatings, whose cross section is curved and which are adapted to the 
shape of the beads to be set. 
Moreover, the embodiment that is illustrated here and that is constructed 
from three jewelry sections 2, 5 and 9, whose diameter becomes smaller 
step-by-step, is only one example, because in the simplest case the 
jewelry article according to the invention can include in the simplest 
case (with respect to the jewelry sections) only two jewelry sections 5 
and 9, in which case the border members 31 and the webs 27 form, for 
example, an ornamental lattice; or the jewelry sections 2 and 5, in which 
case the border members of the receiving openings 7 can form an ornamental 
lattice, instead of receiving gemstones 8 or in which case the border 
members 29 form an ornamental lattice and the openings 25 receive 
gemstones 8 and the openings 7 are designed as viewing openings. And in 
still other engineered shapes four, five or more jewelry sections can be 
used to construct the piece of jewelry according to the invention, whereby 
the individual jewelry sections have preferably a step-by-step decreasing 
size, such as a step-by-step decreasing diameter, whereby preferably the 
viewing openings lie in the direction of the edge or at the edge, whereas 
the receiving openings are located further toward the inside, so that the 
size, for example the diameter, decreases step-by-step continuously by the 
area of the viewing openings. 
In addition to the shapes, listed above by way of examples, the receiving 
openings can have varying suitable shapes as a function of the shape of 
the gemstones or beads, in particular rectangular, square, triangular, 
tear-shaped and/or oval, whereby the viewing openings are designed to 
match. 
Furthermore, it is within the scope of the invention that gemstones or 
beads are not set in all receiving openings, but rather selected receiving 
openings can remain empty for design reasons. 
As explained or implied in part already above, jewelry is provided with the 
invention that enables the exact design at minimum labor and material 
costs, and in which an exact uniform hold of the gemstones and/or beads is 
guaranteed by means of the method according to the invention. 
Even if the invention was explained in the above description with reference 
to a pyramidal jewelry article with circular or polygonal outline, it is 
clear that the jewelry article according to the invention can be designed 
in different geometric shapes. For example, the jewelry according to the 
invention can be also rectangular or square, for example, bent into a 
clasp, which can be worn around the neck, arm or finger. Or the jewelry 
article can have an irregular outline, such as a leaf-shaped or fan-shaped 
outline derived from nature. In all cases it is clear that the jewelry 
article can be both two-layered (two stacked jewelry sections) and also 
multilayered (more than two stacked jewelry sections), in particular for 
example terrace-shaped or in the broadest sense pyramid-shaped, with 
varying basal planes. 
Furthermore, it must be pointed out that the design of the jewelry article 
made of sections that are concave in the direction of its interior, in 
particular concave shells, such as forming a pyramidal shape, is 
especially advantageous, because in an especially thin design of said 
jewelry sections the thickness of the gemstones can thus be integrated in 
the interior of the jewelry article, thus resulting in a light-weight 
jewelry article that is comfortable to wear and feels good to the touch. 
In the conical, truncated, pyramidal or truncated pyramidal jewelry 
articles that are described above and shown in FIGS. 1 to 6, the nut 11 
and the screw 17 are only a preferred embodiment of a central, detachable 
connection, with which all of the jewelry sections including the gemstones 
or beads or the like are held together. Other embodiments of such a 
central detachable connection are, e.g. a bayonet connection, a snap-in 
connection, a lock-in connection or the like. In other jewelry articles of 
the invention, in particular other conical, truncated, pyramidal, or 
truncated pyramidal jewelry articles of the invention, a detachable 
central connection in the above sense can also be provided than the one 
illustrated and/or described. In place of only one central detachable 
connection, several detachable connections of the aforementioned kind can 
also be provided. 
Moreover, in other preferred embodiments of the piece of jewelry according 
to the invention a detachable central connection or several detachable 
connections in the aforementioned sense can be provided in an extremely 
advantageous manner, that are characterized in that they exhibit jewelry 
sections corresponding to jewelry sections 2, 5 and/or 9, but unlike these 
are not conical, truncated, pyramidal or truncated pyrmidal, but rather 
are in general roof-shaped, closed on the side or open on the side, have, 
for example a cross section as shown in FIGS. 5 and 6, if the central axis 
of symmetry 21 is replaced by a plane of symmetry, which extends 
perpendicular to the drawing plane and whose cut line with the drawing 
plane is represented by the line 21. The result is a steep roof-shaped 
piece of jewelry, which exhibits the invention and has at least two 
stacked, roof-shaped jewelry sections along functional lines--i.e. with 
respect to the setting of the gemstones, beads or the like--of the jewelry 
sections 2, 5 and/or 9, but can also include several such jewelry 
sections, thus can form to some degree a multi-stepped roof--similar to 
the multistepped pyramids. 
However, a roof-shaped piece of jewelry according to the invention is not 
restricted to a simple steep roof shape, but rather can be assembled from 
several roof shapes, for example steep roof shapes, which cross, collide 
at an angle, proceed in the shape of a star from a central point and thus 
can have identical or different lengths. 
Thus, the steep roof shape is only one example of a roof shape, since the 
piece of jewelry according to the invention can also have varying 
different roof shapes whose design is simple or assembled, in particular 
roof shapes whose legs are non-uniform, such as a shed roof shape. In 
addition, the cross section of the roof surfaces can be curved, such as 
pagoda roofs, semicircular vaulted roofs, etc. 
Insofar as all of these roof-shaped jewelry articles of the invention have 
flat roof shapes, what they have in common is that the angle .varies. (see 
FIG. 5 under the above condition that the line 21 represents there the 
cutline of a plane of symmetry that is perpendicular to the drawing plane) 
between at least two roof-shaped surfaces of a roof-shaped jewelry section 
is larger than 0.degree. and smaller than 360.degree. and has preferably 
such a size that no jewelry sections, beads or the like project externally 
beyond the actual basal plane of the jewelry article. In the case of 
curved roof surfaces and parts that are in general concave in the 
direction of the interior of the piece of jewelry, in particular concave 
shells, the concavity is chosen preferably in such a manner that no 
gemstones, beads or the like project externally beyond the actual basal 
plane of the jewelry article, thus are located totally within the piece of 
jewelry. 
Even for roof-shaped jewelry articles and the aforementioned parts that are 
concave in the direction of the interior of the jewelry article, in 
particular shells, the detachable connection or several detachable 
connections can have jointly a "hat", which covers the roof ridge or an 
outer region of the jewelry article and whose cross section corresponds to 
the concave parts, in particular shells, as the upper confining flange for 
the jewelry sections, which corresponds to the hat 12 of the embodiments 
described above and--as in the embodiments of FIGS. 1 to 6--becomes an 
integrated piece of the jewelry article, so that from the outside it looks 
in an extremely advantageous manner as if it did not have at all a 
detachable connection. The uppermost jewelry section can also form this 
"hat" in that the one member of one or several detachable connection(s) is 
fastened towards the inside of the jewelry article. 
The jewelry articles, constructed from sections that are concave in the 
direction of the interior of the piece of jewelry, such as the simple 
roof-shaped jewelry or jewelry, which is assembled from several roof 
shapes (see above) and exhibits the invention, and the conical, truncated, 
pyramidal, or truncated pyramidal jewelry according to the invention are 
especially preferred, because they can be designed in such a manner--as 
illustrated--that the gemstones, beads or the like do not project beyond 
the actual basal plane of the piece of jewelry; i.e., their rear side is 
integrated into the interior of the piece of jewelry, and because the 
gemstones, beads or the like can be set with minimum material thickness, 
e.g. sheet metal thickness, of the jewelry sections, and an extremely high 
concentration of gemstones or beads is achieved at a minimum setting cost. 
In so doing, the gemstones, beads, or the like can be replaced, as 
explained above, with additional gemstones, beads or the like, so that 
there are no limits to one's fantasy. 
Thus, the jewelry sections can be in particular generally convex toward the 
outside or concave toward the inside, of which the pyramidal shapes, 
truncated shapes and roof shapes are strictly geometric examples. However, 
other shapes, for example natural shapes such as a leaf shape and shapes 
interpreted with a sensitive artistic understanding, can be selected that 
are also designed convex outwardly or concave inwardly. 
In addition, the gemstones or beads are provided preferably as spacers 
between the jewelry sections. 
Even though in the above the modification of the visual appearance of the 
jewelry with respect to conical, truncated, pyramidal or truncated 
pyramidal jewelry is achieved by rotating the jewelry sections in opposite 
directions around the center axis, a process that can take place in 
general with jewelry that is centrally symmetrical around a center axis, 
the invention is not at all restricted thereto. Thus, in other jewelry 
articles, such as jewelry with more general shapes like stylized leaf 
shapes, the shape based on the arrangement of the webs of the 
lattice-shaped jewelry pattern between laterally adjacent viewing openings 
on the central regions of the gemstones or beads can be modified by moving 
the jewelry sections in opposite directions, so that the detachable 
fastening(s) has/have several fastening positions, in which jewelry 
sections are shifted in opposite directions in the above sense. Another 
solution of the invention for the purpose of arranging by choice the 
aforementioned webs in one and the same piece of jewelry around the edges 
of the gemstones or on their central regions, comprises in the case of 
mirror symmetrical jewelry sections, e.g. those comprising ellipsoid 
concave shells, of arranging differently the gemstones and webs of both 
mirror symmetrical halves in such a manner, e.g. non-symmetrically (which 
can be quite attractive for a piece of jewelry) that in the two possible 
positions (rotated by 180.degree.) of an ellipsoidal concave shell, on the 
one hand, the webs rest on the edges and, on the other hand, rest on the 
central regions of the gemstones (the same applies to beads, instead of 
gemstones).
