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
- 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.
- 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.
- 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.
- The present inventor has recognized that it would be useful, competitively advantageous, and challenging to provide the trade with jewelry pieces incorporating precious and semi precious stone clusters arranged so that the center of the cluster, where the stones meet, defines a cross or any other shape. The invention also focuses on jewelry made or fabricated from smaller, discreet gemstones that are arranged to convey and closely resemble a single larger sized stone into which the cross shape or other shapes appear to have been inscribed.
- 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 simulate an inscribed cross symbol. Preferably, two upper gemstone quadrant sections are smaller in size than two vertically lower gemstone quadrant sections, for proper placement of the cross arms. The jewelry gemstone cluster can be created to have any of a round shape, a square (includes rectangular) shape, an oval shape, a marquis shape, a pear shape, or any shape. Other shapes are possible, for example, a flower, a letter, a star and the like, and the number of stone sections can be 2, 4, 6 or even an odd number of stones.

FIG. 1 illustrates diagrammatically aconventional round diamond 10 with its table 12,crown 14 andpavilion 16. Thediamond 10 can be mounted in around setting 20 with the table 10 andcrown 14 jutting above the setting and theculet 22 protruding at the bottom, all as widely known and shown inFIG. 2 .FIG. 3 shows the bottom view. The conventional diamond can be drilled or laser cut to define across shape 18 in its table 12 as shown inFIG. 4 , but doing so would require a large sized and therefore expensive diamond and a very laborious and expensive process as noted above. - In departure from the prior art, the present invention utilizes, as depicted in the exploded view of
FIG. 5 , four diamond sections orquadrant sections respective table facet 12 a, 12 b, 12 c and 12 d, and arespective crown section 14 a, 14 b, 14 c and 14 d. Most importantly, each diamond quadrant includes two respective cross facets, for example, 13 a 1 and 13 a 2 for thefirst quadrant section 13 a, and similar cross facets for the other three diamond quadrants, namely and respectivelyfacet pairs 13b c 1, 13c 2 and 13d - Each of these “cross” facet pairs is defined in a respective plane that is angled relative to
table facet 12, as well as to being inclined at their bottom edges 13e 1 and 13 e 2 (which extend at right angles relative to each other). The cross facets 13e 1 and 13 e 2 meet at mating or joining edge orsurface 13 m. Each of the other quadrant sections has its respective cross facet pairs, 13 cbl, 13 cb 2; 13cc cc 2 and 13cd - As shown in
FIG. 6 , when the fourdiamond quadrants jewelry setting 20, the cooperation of the adjacently located and juxtaposed cross facet pairs described above results in thecomposite diamond 29, the four diamond constituents of which together define and show an inscribedcross shape 30. Thecross shape 30 extends vertically along thenadir edge 32, and horizontally along the horizontalnadir edge 34, forming the cross arms as shown. Note that the vertically higher,diamond quadrant sections lower quadrant sections 13 c and 13 d, in order to locate thearms 31 a and 31 b of the cross closer to theupper tip 36 of the inscribed cross, to obtain a properly shaped cross symbol. -
FIG. 7 shows a side view ofFIG. 6 , with the setting 31 shown in dashed lines. - The
crowns 14 a, 14 b, 14 c and 14 d of the quadrant sections are faceted similar to a typical “full cut” stone, but other cuts may be used without departing from the scope of the present invention. - In the inscribed
cross 30 ofFIG. 8 , the formation and construction of the cross is generally identical to the above description, except that the overall setting and shape of the diamond quadrants forms an overall four-sided, i.e., square or rectangle shape 40. In the same vein, the overall shape of the embodiment inFIG. 9 is oval.FIG. 10 presents the marquis shape andFIG. 11 the pear shape. Of course, other shapes, for example, polygonal, are also within the scope of the invention. - In the preceding description, the invention has been described relative to a preferred embodiment in which the cross shape is defined by four diamonds located in four quadrants of a circle or of a pear and the like. However, it is within the scope of the invention that the invention is realized by utilizing less or more than four diamond sections. Thus, in relation to
FIG. 5 , each of the twolower sections 13 c, 13 b can itself consist of two sections making for a total of 6 sections. Conversely, the twolower diamond sections 13 c, 13 d can be fashioned from a single diamond stone, and so could theupper diamond sections - Reference is also made to
FIG. 12 , which shows the invention in an embodiment where it defines the letter “M”. But as noted elsewhere in this description, any shape can be realized using the technique of the present invention. Still further, although the invention is described relative to creation of facets that simulate the look of a shape that is inscribed or cut into the tables of the diamonds, the invention can be realized by cutting away the outside portions of the tables and leaving an upraised shape in the form of cross or a letter, a symbol, etc. - Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.
