Abstract:
A method for making customizable liquid-filled glass jewelry wherein a hollow glass vessel is blown or otherwise manufactured and then partially filled with small diamonds, gems, stones, pieces of metal, etc. Thereafter, the hollow glass vessel is completely filled with a semi-viscous liquid having a specific index of refraction. Once filled with liquid, a sealing cap is attached to the glass vessel, the cap typically being decorative. With a properly selected index of refraction, the vessel appears to be solid glass with the small diamonds, etc. being suspended therein. Colorized diamonds produced by irradiation produce particularly attractive results. A process for creating custom molds for blowing custom glass vessels is described. Molds are created using instructions derived from images generated by 3-D solid rendering software to direct a numerically controlled milling machine or other such machine tool.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention pertains to glass jewelry and, more particularly, to a customizable ornamental glass jewelry article including color enhanced gems in a liquid and a method for manufacturing same. 
       BACKGROUND OF THE INVENTION 
       [0002]    The manufacturing of glass artifacts dates back at least as far as the Roman Empire. Artisans have long been challenged to find new ways to create both functional and ornamental articles from glass. Glass blowing as a means to produce these articles has been practiced nearly since the discovery of glass itself. In more modern times, one of the desirable and valuable aspects of hand-blown glass articles resides in the unique, one-of-a-kind nature of the pieces that individually made articles possess. In today&#39;s age of mass production, articles that possess the quality of artisanship and uniqueness command a well deserved premium. 
         [0003]    Mass production of glass articles was enabled by the development of mold-blowing techniques, where the glass article is inflated into a mold having a pre-defined design, providing the ability to reproduce multiple copies of a specific glass article design. While this method provides for improvements in the economy of scale, and the ability to define a repeatable process for the production of glass articles, it also removes the spontaneous artistic flair and one-of-a kind artisanship described above. 
         [0004]    Another class of highly ornamental and valuable objects includes valuable stones, gems, and diamonds, which are desired both for their relative rarity in nature, their inherent beauty, and the skill and craftsmanship required by an artisan in the jewelry trade to cut, polish, or otherwise prepare them for maximum beauty and luster, and mount them in an appropriate setting. In some cases, it can be desirable to enhance the color of diamonds or gems to increase their inherent value, and to enhance their desirability for a specific setting or purpose. Some processes that have been used to enhance the color of diamonds included irradiation by protons and deuterons in a cyclotron, gamma ray bombardment from exposure to cobalt-60, neutron bombardment from exposure to nuclear (i.e., “atomic”) piles, and electron bombardment using Van de Graff generators. Subsequent heating to elevated temperatures may also be performed to further alter the color, as desired. Methods of coating the diamonds, stones, or gems may also be employed to produce additional colors that the irradiation methods do not produce. 
         [0005]    Still another class of material suitable for inclusion in such custom liquid-filled glass jewelry is small pieces of metal. Such metal may included small stamped, photo etched, laser cut, or otherwise processed thin metal sheet in the form of decorative designs or words, for example, names. 
         [0006]    The relatively recent increase in value of precious metals has created a growing market for the purchasing and recycling of jewelry and other precious metal items. While the precious metal content is often the focus of this market, diamonds, gems, stones, and smaller precious gem particles are also byproducts of the recycling process. Depending on their size and quality, these precious gems may be retained and mounted in a new setting. The difficulty in reusing (e.g., resetting) small gems arises in matching cut, matching quality/color, and/or matching sizes. However, the recycling process described tends to produce an excess, particularly, of the smaller sizes that are used to accentuate the featured gems in many precious metal settings. It would be advantageous to develop a cost effective way to use these gems, as well as enhance the desirability and value of larger stones, diamonds, and gems that have been acquired or recycled. 
       DISCUSSION OF THE RELATED ART 
       [0007]    The existing prior art has provided a composite gem and jewel, describing a double-globular glass housing that contains gem fracture fragments and a viscous fluid such as glycerin, for use as a pendant jewel, as described in U.S. Pat. No. 1,850,190 for COMPOSITE GEM AND JEWEL issued Mar. 22, 1932 to Horace W. Welch. The double-globular glass housing provides a means to attach a clasp on which to hang or mount the glass housing. 
         [0008]    U.S. Pat. No. 1,912,602 for FLOATING OPAL AND THE LIKE issued Jun. 6, 1933 to Samuel Stonburg combines a transparent hollow body containing s-tetrabromoethane or a mixture of s-tetrabromoethane and carbon tetrachloride of sufficient specific gravity to hold a gem in suspension, such liquid being not transparent, but rather somewhat translucent to prevent otherwise clear definition of the outline of the gem particles. 
         [0009]    U.S. Pat. No. 4,142,383 for LIQUID FILLED SEALED GLASS ORNAMENT AND METHOD issued Mar. 6, 1979 to Wolfgang R. Eberhart provides for a glass receptacle filled with a viscous fluid such as glycerin, containing flaked metals or minerals. It discloses a process to grind a specific conical shaped outline at the top of the receptacle, and bonding a cap with a resin. 
         [0010]    U.S. Pat. No. 4,208,888 for JEWELRY STORING AND DISPLAYING NATURAL PLACER GOLD issued Jun. 24, 1980 to Ann L. Erdman et al. discloses a hand-blown vial designed to hold flakes or nuggets of placer gold. 
         [0011]    U.S. Pat. No. 5,006,375 for ORNAMENTAL ARTICLE issued Apr. 9, 1991 to Louis H. Mangan discloses an ornamental article comprising a transparent housing, totally sealed and holding particulate material and a liquid under sufficient vacuum to cause the liquid to boil under ambient conditions. 
         [0012]    U.S. Pat. No. 5,013,145 for EYEGLASSES WITH LIQUID FILLED LENSES issued May 7, 1991 to Theodore P. Croll discloses eyeglasses with ports that allow easy filling and refilling of liquid between eyeglass and introduction of floating and non-floating decorative materials. 
         [0013]    None of the patents and published patent applications, taken singly, or in any combination are seen to teach or suggest the novel ornamental glass jewelry article, or the method of manufacturing the article of the present invention. 
       SUMMARY OF THE INVENTION 
       [0014]    In accordance with the present invention there is provided an article of jewelry that utilizes diamonds, diamond chips, or other stones, gems or fragments, or small pieces of other materials in a cost effective method for the shape, size, or quality of the diamonds, gems, or stones obtained. The diamonds, gems, or stones may be obtained from the recovery of recycled precious metal jewelry, but are not limited to that method. The invention provides a method to use these items that does not require investing the labor and materials to mount them in a precious or semi-precious metal setting. 
         [0015]    The present invention provides an item of jewelry, and method of producing the item of jewelry, comprising a glass article with an interior cavity with an opening at one end. The interior cavity is subsequently partially filled with preferably diamonds, or diamond pieces that have been processed to enhance their color and/or contrast. Likewise, other stones, gems or stone or gem fragments, metal pieces, or a combination thereof may be substituted for diamonds. The glass article is typically produced in a mold, created by Computer Numerically Controlled (CNC) milling machine or similar machine tool in graphite mold blank. Mold blanks from materials other than graphite may be substituted. The CNC milling machine is driven by a solid model generated from SolidWorks™ or a similar type 3D modeling software program. When desirable, the glass article can be customized by altering the form of the glass after its removal from the mold, while the glass is still malleable. Such customization typically results in a one-of-a-kind jewelry piece. 
         [0016]    While molding with possible post-molding shaping while the object is still hot enough to be malleable have already been discussed. However, there are other ways in which unique objects may be formed from glass. For example, a tool resembling a pair of so-called needle nose pliers may be used to form glass objects having a standard sized and shaped top. While standard top portions allow fitting standard caps to the object. However, great latitude is given to the glass artist in forming a lower section (i.e., the region beyond the standard top). This allows creation of truly one-of-a-kind glass objects. 
         [0017]    While clear glass is generally used, colored glass may also be used to enhance a particular effect. 
         [0018]    Processing methods used to enhance color of diamonds or diamond chips generally include irradiation or coating methods. Irradiation of diamonds can be performed using a number of methods that impart various colors or hues to the diamonds. These methods include irradiation processes such as proton and deuteron bombardment using a cyclotron, gamma ray bombardment with exposure to cobalt-60, neutron bombardment by neutrons from a nuclear reactor (i.e., so called “atomic” or nuclear piles), and electron bombardment using a Van de Graff generator. Additionally, the diamonds can be annealed at an elevated temperature to obtain additional color variations. Using these methods, color hues in the yellow, red, orange, green, and blue ranges can be obtained. 
         [0019]    It is also known to coat diamonds or other gems to produce still other colors. 
         [0020]    It will be recognized that processes for coloring diamonds or other gemstones are believed to be well known to those of skill in the art. Any suitable coloring process may be used. The actual coloring process itself forms no part of the present invention. 
         [0021]    The interior cavity is further filled with a semi-viscous fluid with refractive properties close to that of glass, such that no air remains in the glass piece so that the jewelry gives the appearance of a solid glass piece, with color enhanced diamonds, diamond pieces, stones, or gems floating and moving within. The glass article is then capped with a metal or other suitable material, attached using a resin or other suitable adhesive to adhere the cap to the outside surface of the glass article. The cap can include functional elements that allow for attaching or mounting the item of jewelry to a chain or hook or any mounting method desired. 
         [0022]    It is, therefore, an object of the invention to provide an ornamental liquid-filled glass jewelry article having flakes, particles, or pieces of solid material suspended in a liquid. 
         [0023]    It is another object of the invention to provide a cost effective method of using diamonds, diamond pieces, stones, and gems that may be of marginal value for other jewelry applications. 
         [0024]    It is an additional object of the invention to provide a method to enhance the color of diamonds, diamond chips, stones, gems, and the like to create interest in the ornamental glass jewelry article. 
         [0025]    It is yet another object of the invention to combine glass of a controlled refractive index with a liquid with a comparable refractive index with diamonds colored by irradiation to optimize color and color intensity in the liquid-filled glass jewelry piece. 
         [0026]    It is a further object of the invention to provide a process for the manufacturing of the ornamental glass jewelry article. 
         [0027]    It is yet another object of the invention to provide a method to custom shape the glass portion of the ornamental glass jewelry article. 
         [0028]    It is still another object of the invention to provide a method to form the glass portion from clear or colored glass. 
         [0029]    It is a still further object of the invention to provide a tool for blowing objects having a standard top region but a truly free form bottom section.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0042]    The present invention provides items of jewelry or similar decorative articles, each having a liquid-filled glass container. The glass container has small pieces of material suspended in the liquid that is sealed within the glass container. 
         [0043]    Referring first to  FIG. 1 , there is shown a perspective schematic view of an exemplary article of liquid-filled glass jewelry in accordance with the invention, generally at reference number  100 . 
         [0044]    Jewelry object  100  has a glass body  102 . Glass body  102  is typically hollow and is constructed as discussed in detail hereinbelow. Glass body  102  also typically has a decorative outside profile  120 . Said decorative outside profile  120  may assume a shape representing a recognizable object, such as a handbag, a globe, or alternatively may assume an amorphous shape without reference to another object. 
         [0045]    A hollow interior cavity  104  formed within glass body  102  typically is completely filled with a liquid  106 . Liquid is typically transparent and has an index of refraction chosen to optically cooperate with the index of refraction of the glass body  102 . In addition, the viscosity of the liquid controls how the suspended diamonds or other materials  108  physically behave in the liquid. Glycerin is one suitable liquid for use within hollow interior cavity  104  of glass body  102 . The viscosity of Glycerin makes the diamonds or other materials  108  fall at a rate that is aesthetically pleasing when the object is inverted and then righted. If, for example, water or baby oil were used, each having a similar refractive index, the diamonds  108  would almost instantaneously sink to the bottom, whereas with the glycerin the diamonds slowly flip and turn as they make their way to the bottom of the glass allowing the wearer to admire the stones as they sink. Glycerin also provides a sufficient boundary layer on the interior surface of hollow glass body  102  to protect it from being scratched by the diamonds. 
         [0046]    While indices of refraction of glass body  102  and liquid  106 , respectively, are typically chosen to be relatively close to one another, it will be recognized by those of skill in the optical arts that mismatching the respective indices of refraction may create desired optical effects. Consequently, the invention is not considered limited to a particular relationship between these indices of refraction. Rather, the invention is intended to include any relationship of indices of refraction between glass bodies  102  and liquids  106 . 
         [0047]    Pieces of solids  108  are placed into interior cavity  104  of glass body  102 . Solids may be chosen from gemstones, especially colorized diamonds or diamond chips. Solid materials suitable for use in jewelry object  100  are discussed in more detail hereinbelow. 
         [0048]    A bottom region of glass body  102  is typically sealed. In particular, glass body  102  is typically formed with a sealed, contiguous bottom  110 . 
         [0049]    A top region  112  is sealed by a cap  114 . In the example of jewelry object  100 , a cap  114  is configured to resemble the top of a purse or handbag. It will be recognized by those of skill in the art that cap  114  may take on a vast number of different decorative appearances as long as cap  114  acts to seal glass body  102  thereby retaining liquid  106  and solid material  108  within hollow interior cavity  104  thereof. Consequently, the invention is intended to include any variant of cap  114  suitable for sealing a top region  112  of glass body  102  as well as the example chosen for purposes of disclosure. 
         [0050]    Cap  114  is attached to top  112  of glass body  102  with any known material, not shown, or technology. Typically, cap  114  is attached to glass body  102  with adhesive, not shown, that bonds the cap  114  securely to glass body  102  as well as forms a liquid-tight connection therebetween. Typical cements or bonding agents include clear epoxies with short cure times, so-called “instant” adhesives, and UV curing adhesives. 
         [0051]    Alternately, it may be possible to ultrasonically weld or otherwise fuse cap  114  to top  112  of glass body  102 . Techniques for so doing are believed to be known to those of skill in the art and, consequently, such techniques are neither further disclosed nor discussed herein. The cap  114  serves the multiple purposes of augmenting the appeal of the completed jewelry object  100 , sealing the opening  140  ( FIG. 6 ) so that the liquid cannot leak out and air cannot leak in, and providing a means, such as a loop  116  or hook to attach the article of jewelry to another item, for example, a mount, or a chain, neither shown. 
         [0052]    Referring now also to  FIG. 2 , there is shown a three-dimensional rendering of the glass body  102  of an exemplary jewelry article  100  in accordance with the invention, generally at reference number  120 . Rendering  120  is created by three-dimensional modeling software and contains only the general decorative outside profile of the article required for the subsequent manufacturing of a glass blowing mold. It will be recognized that additional surface decorative raised detail could be added. 
         [0053]    Solid modeling software is believed to be well known to those of skill in the art and, consequently, such software is not further discussed herein. For purposes of disclosure SolidWorks®, a three-dimensional CAD program provided by Dassault Systémes SolidWorks Corp. of Waltham, Mass. has been found suitable for use. It will be recognized by those of skill in the art that other suitable three-dimensional CAD software may exist and any other suitable software may be used to create a three-dimensional rendering  120  of glass body  102  or other solid components of jewelry item  100 . 
         [0054]    Another product Mastercam® by CMC Software of Tolland, Conn. USA may be used to create instructions, not shown, from the three-dimensional rendering  120 . These instructions subsequently direct the movements of a numerically controlled milling machine or another suitable machine tool for producing a mold to reproduce the glass body  102 . The procedures for creating instructions for numerically controlled machine tools is believed to be known to those of skill in the art and are not further discussed herein. 
         [0055]    Referring now also to  FIG. 3 , there is shown a perspective view of blank interchangeable mold stock blocks  310  used to create a first portion of a glass blowing mold  320   a . A cooperative second portion of a glass blowing mold  320   b  ( FIG. 5   d ) is also produced in a similar manner. In the embodiment chosen for purposes of disclosure, mold stock blocks  310  are made from graphite. However, it will be recognized that mold stock block  310  may be made from other suitable materials known in the mold-making and glass manufacturing industries. A mold  320   a ,  320   b  formed from mold stock blocks  310  may be used to produce one or more unique glass articles therefrom. A mold for producing a few glass objects may, of course, be different than a production mold designed to form objects in substantially larger numbers. As is well known to those of skill in the mold making and/or glass blowing arts, each mold must have two mold halves. 
         [0056]    Mold stock block  310  has a face  312  for receiving an engraved or machined mold pattern  322   a  ( FIG. 4 ) therein. 
         [0057]    An alignment hole  316  is provided in a face  312  for aligning faces  312  of respective mold halves  320   a ,  320   b  in alignment with one another. 
         [0058]    Shoulders  314   a ,  314   b  and a hole  318  are provided for aligning and securing mold halves  320   a ,  320   b  in a mold clamping and aligning tool  350  ( FIGS. 5   a ,  5   b ,  5   c ) as described in detail hereinbelow. 
         [0059]    Referring now also to  FIG. 4 , there is shown a perspective view of first of a pair of mold halves  320   a ,  320   b  (only one shown) formed from blank mold stock blocks  310  after a design  322   a  (e.g., profile  120 ) has been engraved or machined into face  312  thereof to form a mold cavity. Typically, the mold cavity  320   a  is created by a numerically controlled CNC milling machine, not shown and forming no part of the present invention, using instructions generated by suitable software, not shown, to translate a three-dimensional CAD model into such instructions for use by the CNC milling machine. 
         [0060]    As previously stated, each mold needs two halves. A second mold half  320   b , not shown in  FIG. 4 , is subsequently produced. However, second mold cavity  322   b  may be either symmetrical (i.e., a mirror image) to first mold cavity  322   a  or may be asymmetrical (i.e., contain pattern differences when compared to design of mold cavity  322   a  in first mold half  320   a  thereto. 
         [0061]    Note that an alignment hole  316  is provided for aligning first mold half  320   a  with a corresponding second mold half  320   b , not shown in  FIG. 4 . 
         [0062]    Referring now also to  FIGS. 5   a ,  5   b , and  5   b , there are shown top plan, side elevational, and side perspective views, respectively, of a mold clamping and aligning tool  350 . Tool  350  is adapted to receive and retain pairs of interchangeable mold halves (e.g., mold halves  320   a ,  320   b ) so that hollow glass bodies (e.g., glass bodies  102 ) may be blown within. 
         [0063]    Tool  350  has a jaw region  352  having a pair of securing clips  354   a ,  354   b  adapted to slidably receive and retain respective ones of mold halves  320   a ,  320   b  in a face  312  to face  312  alignments. Shoulders  314   a ,  314   b  are retained under edges  356   a  and  356   b  of securing clips  354   a ,  354   b , respectively. 
         [0064]    Referring now also to  FIG. 5   d , there is shown the jaw region  352  of tool  350  of  FIG. 5   a  with mold halves  320   a ,  320   b  in place with a mold formed therefrom ready to receive molten glass in a mold cavity formed from individual mold cavities  322   a ,  322   b  completely defining the shape of a hollow glass structure to be blown within cavity formed by cavities  322   a  and  322   b . An opening  524  between mold halves  320   a ,  320   b  allows insertion of a blowpipe, not shown, having a glob of molten glass, not shown, on a distal end thereof into the mold cavity. Blowpipes and techniques for using them are believed to be well known to those of skill in the glass blowing art. Consequently, blowpipes and glass blowing is not further discussed herein. 
         [0065]    Once a glass body  102  within mold halves  320   a ,  320   b  has cooled sufficiently, jaws of clamping and alignment tool  350  may be separated allowing mold halves  320   a ,  320   b  to also be separated and the partially cooled glass body  102  to be withdrawn. Once glass body  102  is ejected, a diamond blade, or similar tool, neither shown, may be used to cut glass body  102  off the blowpipe. Once glass body  102  is cut off the blowpipe, a lapping wheel or other similar tool, neither shown, may be used to smooth the cut edge. It will be recognized that because glass may be reheated to a malleable state, the glass body  102  may be cut off the blowpipe at a later time if desired. 
         [0066]    At this point, the still malleable glass may be additionally worked to impart individual variations into the glass of each individual glass body  102 . It will be recognized that because glass may be reheated to a malleable state, the additional working may be performed at a later time if desired. 
         [0067]    While heretofore only molded glass bodies  102  have been discussed. Referring now to  FIGS. 7   a  and  7   b , there are shown a tool  400  for blowing free form hollow glass bodies  402 , and a free-form glass body  402  formed with tool  400 , respectively. Tool  400  is typically manufactured from a standard pair of needle nose pliers. Brass is chosen to avoid heated glass, not shown, from sticking to or otherwise adversely interacting with tool  400 . Tool  400  has a circular opening  404  formed in the jaw region, not specifically identified, opening  404  having a predetermined diameter  406 . To make tool  400 , a predetermined shape may be milled into standard needle nose pliers using a CNC milling machine or a similar machine tool. Opening  404  may be separated by opening the handles, not specifically identified, of tool  400 . Diameter  406  corresponds to a desired diameter of a final blown glass object  404  allowing a standard cap  114  to be attached to an upper portion  408  thereof. By blowing glass object  402  or the like through opening  404  allows great artistic latitude in forming the remainder (i.e., the lower portion of the body) of glass object  402 . As glass object  402  is hollow and has a standard upper portion for attaching a cap  114  as described elsewhere herein. Hollow glass object  402  is a single example chosen for purposes of disclosure. It will be recognized by those of skill in the art that a virtually unlimited number of freeform hollow glass object may readily be formed using tool  400 . This is one way of creating one-of-a-kind jewelry objects  100 . 
         [0068]    Referring now also to  FIG. 6 , there is shown front perspective view of an exemplary glass body  102 . Glass body  102  has a decorative outside profile  120 , a hollow interior cavity  104 , and an opening  140  at an upper end. Note that upper end  140  has been severed from the blowpipe and worked to have a smooth upper edge to facilitate attaching a cap as discussed hereinbelow. 
         [0069]    While glass body is typically formed from clear glass, it will be recognized that in alternate embodiments, colored glass may be used to achieve a desired overall effect in jewelry object  100 . Consequently, the invention is not considered limited to any particular color glass. 
         [0070]    Referring now also to  FIG. 8 , there is shown a perspective view of glass body  102  after the pieces of solid material  108  have been placed in the hollow interior cavity  104  through the opening  140 . The pieces of solid may include color enhanced diamonds or diamond pieces, stones, gems, shaped metal pieces, or any other items desired. Other artifacts may be placed in the interior cavity to personalize the jewelry, including but not limited to cut or formed metal pieces shaped to represent an object of interest. These could be pieces cut to represent names, words, or objects, such as charms or figures, or any other desirable representation. Many methods to enhance the color of diamonds or diamond chips are known in the industry, including irradiation by protons and deuterons in a cyclotron, gamma ray bombardment from exposure to cobalt-60, neutron bombardment from exposure to nuclear piles, and electron bombardment using Van de Graff generators. Subsequent heating to elevated temperatures may also be performed to further alter the color, as desired. Additionally, methods of coating the diamonds, stones, or gems, including vacuum deposition processes such as chemical vapor deposition (CVD), sputtering, or evaporation, may also be employed to produce additional colors that the irradiation methods do not produce. It will be recognized by those skilled in the art that other suitable methods to enhance the color of diamonds, diamond chips, stones, gems, or other pieces of solid  108  may be used. 
         [0071]    Referring now also to  FIG. 9 , there is shown the glass body  102  after both pieces of solid material  108  and a liquid  106  been placed in the hollow interior cavity  104  such that the interior cavity is filled completely up to the opening  140 . The filled glass body  102  is now ready to receive a cap  114  ( FIG. 1 ) previously described. Liquid  106  is typically transparent and chosen to optically cooperate with the index of refraction of the glass body  102  to give the appearance of solid glass, but may alternatively be translucent, or colored to cooperate with or accent the pieces of solid  108 . Liquid  106  may be poured into said glass body  102 , or deposited using an eye dropper or syringe to fill said glass body  102  to the opening  140 , or using any technique known in the industry to transfer fluid to the interior cavity  104 . The jewelry object  100  is completed by attaching a cap  114  ( FIG. 1 ) to glass body  102  as previously described. 
         [0072]    Since other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the example chosen for purposes of disclosure, and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention.
