Multiple gemstone setting simulating a large gemstone
The present invention relates to a gemstone assembly that includes a prong assembly and a gemstone assembly. The prong assembly includes a plurality of prong members adapted to receive the gemstone assembly therein. The gemstone assembly is in the shape of a diamond with at least a cutlet, a pavilion, a girdle, a crown, and a table, each of which is set with small diamonds to give the appearance of one large diamond. The gemstone assembly has a multidimensional base that includes an upper portion and a lower pavilion portion that are engaged and disengaged by up and down movement thereof.
1. Field of the Invention
This invention relates generally to jewelry and gemstone settings and more particularly to a gemstone setting wherein a plurality of small diamonds are set to simulate the appearance of a large diamond.
2. Description of the Related Art
Different types of gemstone settings are employed by jewelers to hold different types of gemstones in place. These settings secure the gemstones and also add to the aura of the gemstones by significantly enhancing their brilliance and scintillation. The selection of settings is determined by the shape and cut of a gemstone. Large gemstones such as, for example, a large standard round brilliant (SRB) diamond are most coveted in any jewelry setting. However, large gemstones are very expensive, whereas settings wherein a plurality of small to very small gemstones is employed offer an affordable choice to buyers. For example, melee diamonds—small diamonds wherein the diamond weight range from 0.001 carats to 0.18 carats—are used in micro pave settings.
The gemstone settings in the prior art use small to very small diamonds as accent diamonds to the primary diamonds. These small accent diamonds accentuate large primary diamonds. Further, the arrangements of small diamonds in these settings do not follow an asymmetric pattern to present a single organic unit as standard gemstone shape. The arrangement as a single shape does not offer the appearance of parts of an SRB diamond such as for example, a pavilion, a culet, a table, a girdle and a crown, and various other standards that are associated with standards gemstone shapes. A gemstone setting wherein very small gemstones set so as to present an appearance of a large gemstone, such as, for example, a large SRB diamond, is absent in the prior art.
Therefore, a gemstone setting is needed that (1) sets very small gemstones so as to simulate the appearance of a large gemstone and all the critical gemstone parts and features with added brilliance and scintillation and (2) provides an alternative to a large gemstone setting is needed.
SUMMARYA gemstone assembly is disclosed. The gemstone assembly includes a multidimensional base having an upper portion and a lower portion joined together to form the multidimensional base. The multidimensional base is adapted to facilitate the setting of the plurality of gemstones to simulate at least a culet, a pavilion, a girdle, a crown, a table and a plurality of facets to provide the simulated look of a large gemstone.
The above mentioned and other features, aspects, and advantages of the present invention will become better understood with regard to following description, appended claims and accompanying drawings, wherein like reference numbers refer to similar parts throughout the several views where:
It should be understood that the drawings are not necessarily to scale. In certain instances, details which are not necessary for an understanding of the present invention are shown. It should be understood, of course, that the invention is not limited to the particular embodiments illustrated herein.
DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTIONThe embodiments of the invention shown and discussed herein are illustrative of modes of application of the present invention. Reference to details in this discussion is not intended to limit the scope of the claims to these details, or to the figures used to illustrate the invention.
A gemstone setting 100 in accordance with the present invention that uses a plurality of small diamonds that are set close together in the shape of a three-dimensional faceted diamond. Referring to

As shown in the figure, a plurality of bead like prongs 134 is represented by dotted triangles at the four corners of the rectangles 128. The plurality of gemstones 118 are clustered together with little or no metal showing within the beads 134. Although each stone 118 is set in four beads 134 at four corners, each stone 118 may share a common bead 134 with the adjacent stone 118. The beads 134 and the gemstones 118 are at same level and there is little metal between adjacent gemstones 118.
It is noted here that the bead setting is also achievable with tiny prongs already cast in the metal. Melee diamonds are set into a design. The design has multiple tiny little prongs perfectly formed in the prototype or wax. Preferably investment casting is used for the purpose. However, other process may also be used.
The highly precise setting of very small diamonds 118 into the chosen design and shape is accomplished. In some embodiments, the plurality of gemstones 118 is preferably set to be almost on the same level as that of the surface on the ring. However, in other embodiments the gemstones may not be on the same levels as that of the surface ring.

The pavilion portion 142 has a plurality of faces 152. The pavilion portion 142 is preferably hollow from inside and has a lower girdle portion 154 that includes at least a pair of holes 156 located on a lower girdle top surface 158 to receive inserts 150. The pavilion portion 142 has a bottom insert 160 that engages with the prong assembly 102.
The upper and the lower pavilion portions 140, 142 are moved up and down appropriately along the directions indicated by the bidirectional arrow to achieve engagement and disengagement. Both portions 140, 142 meet to form the complete multidimensional base 138. The upper girdle portion 148 and the lower girdle portion 154 combine and define the girdle 124.

Another important feature of the gemstone setting 100, in accordance with the present inventions is that the multidimensional base 138 is separable. The use of a separable base 138 allows a jeweler to create gemstone assemblies that simulate or resemble a variety of standard gemstone shapes, as faithfully as possible. The separable base 138 allows a jeweler to maintain strict focus on implementing various norms pertaining to each stone shape such as, for example, proper width and height proportions and/or angle between the table and the crown. The separable base 138 allows a jeweler to expedite the stone setting process. The use of separable parts also allows a jewelry user to conveniently replace the base portions conveniently when they are damaged.
Once the stones 118 are set in stone seats the gemstone assembly 116 is complete and ready to be mounted in the prong assembly 102, like a large gemstone. Depending upon the design need, the jeweler may opt either for the bottom insert 160 of the gemstone assembly of

In this particular embodiment, the prong assembly has four prong arms. However, the number of prong arms may be varied based upon various design considerations such as, for example, the gemstone shape being simulated by the gemstone assembly 116.
The gemstone assembly 112 is constructed in accordance with the present invention presents not only very clean and neat simulations of large gemstones, but also adds to the brilliance and scintillation of the jewelry. The gemstone setting also gives flexibility to users to use very small inexpensive gemstones to provide a gemstone assembly that can be made to resemble a variety of large gemstones of their choosing.
