Benefits of technology

[0005]The foregoing and other objects of the invention are realized in a jewelry stone cluster defining a cross or any other shape and including a setting, and preferably four gemstone quadrant sections located in the setting juxtaposed to each other. Each gemstone quadrant section includes a table facet and a respective pair of adjacent cross facets, with the cross facets extending in planes that are at an angle to their respective table facet such that the four pairs of juxtaposed cross facets together define or simula

Embodiment Construction

[0019]FIG. 1 illustrates diagrammatically a conventional round diamond 10 with its table 12, crown 14 and pavilion 16. The diamond 10 can be mounted in a round setting 20 with the table 10 and crown 14 jutting above the setting and the culet 22 protruding at the bottom, all as widely known and shown in FIG. 2. FIG. 3 shows the bottom view. The conventional diamond can be drilled or laser cut to define a cross shape 18 in its table 12 as shown in FIG. 4, but doing so would require a large sized and therefore expensive diamond and a very laborious and expensive process as noted above.

[0020]In departure from the prior art, the present invention utilizes, as depicted in the exploded view of FIG. 5, four diamond sections or quadrant sections 13a, 13b, 13c and 13d. Each diamond quadrant has a respective table facet 12a, 12b, 12c and 12d, and a respective crown section 14a, 14b, 14c and 14d. Most importantly, each diamond quadrant includes two respective cross facets, for example, 13a1 and...

Abstract

A jewelry stone cluster comprising four gemstone sections which are mounted in a setting and which are juxtaposed to each other. Each gemstone section includes a table facet and, in one form, a respective pair of adjacent cross facets, with the cross facets extending in planes that are at an angle to their respective table facet. Together, the four pairs of juxtaposed cross facets define an inscribed cross symbol. Preferably, the upper gemstone quadrant sections are smaller sized, so that the arms of the cross are located vertically higher. The overall shape of the gemstone cluster can be round, four sided, oval, marquis, pear, polygonal or any shape.

Description

BACKGROUND OF THE INVENTION[0001]The present invention is directed to diamond jewelry and, more particularly, to a mosaic or cluster of diamonds that together define or show or form a particular item or shape, for example, the Christian, or any, cross symbol.[0002]In the field of diamond jewelry it has been known to shape a diamond into a cross shape and / or to cluster or combine diamonds and / or other precious or semi-precious gemstones so that the diamonds have an overall cross shape. Representative prior art includes U.S. Pat. Nos. D368,869; D465,742; D464,904; D466,044; and 6,546,305, the contents of which are fully incorporated herein by reference.[0003]It is also possible to carve into the table of a diamond a cross shape, but the process would be difficult, costly, and require a large diamond to realize a cross shape that is easily discernable to the un-aided human eye, i.e. without the use of a jeweler's loop or other magnifying implements.[0004]The present inventor has recogn...
