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.
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's age of mass production, articles that possess the quality of artisanship and uniqueness command a well deserved premium.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
While clear glass is generally used, colored glass may also be used to enhance a particular effect.
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.
It is also known to coat diamonds or other gems to produce still other colors.
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.
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.
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.
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.
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.
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.
It is a further object of the invention to provide a process for the manufacturing of the ornamental glass jewelry article.
It is yet another object of the invention to provide a method to custom shape the glass portion of the ornamental glass jewelry article.
It is still another object of the invention to provide a method to form the glass portion from clear or colored glass.
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.

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.
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.
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.
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.
A bottom region of glass body 102 is typically sealed. In particular, glass body 102 is typically formed with a sealed, contiguous bottom 110.
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.
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.
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 (

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.
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.

Once a glass body 102 within mold halves 320a, 320b has cooled sufficiently, jaws of clamping and alignment tool 350 may be separated allowing mold halves 320a, 320b 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.
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.
While heretofore only molded glass bodies 102 have been discussed. Referring now to
