The invention is particularly useful with respect to diamonds, and is therefore described below with respect to diamonds, but it will be appreciated that the invention could also advantageously be used with other gemstones, such as emeralds, rubies, etc.
The value of a gemstone, and particularly of a diamond, increases disproportionately with its size and weight. For example, the value of a diamond of a particular size and weight is considerably more than four times the value of a diamond one— fourth of the respective size and weight. Many "invisible setting" constructions have been devised for mounting a plurality of individual diamonds in a manner to create the impression that they constitute a single diamond, but such "invisible setting" constructions are not only expensive to implement since they require mounting each diamond individually, but they also have varying degrees of success with respect to their "invisibility".
OBJECTS AND BRIEF SUMMARY OF THE PRESENT INVENTION
An object of the present invention is to provide a gemstone construction comprising a plurality of individual gemstones assembled together by a common frame to define a composite gemstone unit which, to the naked eye, creates the impression of a single gemstone and which can be mounted as a single gemstone. Another object is to provide such a gemstone construction particularly advantageous for diamonds.

DESCRIPTION QF PREFERRED EMBODIMENTS
As indicated earlier, the invention is particularly useful, and is therefore described below, for producing a composite gemstone unit from a plurality of smaller individual gemstones assembled together by a common frame. The invention is described below, for purposes of example only, with respect to a number of preferred embodiments utilizing diamonds. In each such embodiment, a plurality of individual diamonds are assembled together by a common frame to define a composite diamond unit having a girdle, a crown on one side of the girdle, and a pavilion on the opposite side of the girdle. Each of the individual diamonds defines a segment of the composite gemstone unit, and includes a girdle segment of the composite diamond unit girdle, a crown segment of the composite diamond unit crown, and a pavilion segment of the composite diamond unit pavilion. The girdle crown segments of at least some of the individual diamonds have an outer face to serve as the outer face of the composite diamond unit girdle and crown. The girdle segment of at least some of the individual diamonds have at least one flat, smooth, inner face in contact with a corresponding flat, smooth, inner face of another individual diamond in the composite diamond unit. The common frame engages the girdle segments of the individual diamonds to press the flat, smooth, inner faces of the individual diamonds into firm contact with each other such that the composite diamond unit appears substantially seamless to the naked eye.
For purposes of example, the invention is described below with respect to a number of embodiments in each of which each individual diamond is of triangular configuration. The described preferred embodiments include embodiments wherein the composite diamond unit is: (1) of square configuration and is constituted of four individual diamonds (Figs. 1-6); (2) of triangular configuration and is constituted of four individual diamonds (Figs. 7-10); (3) of rhombic configuration and constituted of two diamonds (Figs. 11-14); (4) of trapezoidal configuration and is constituted of three diamonds (Figs. 15-18); and (5) of hexagonal configuration and is constituted of six diamonds (Figs. 19—22). The Embodiment of Figs. 1-6
As indicated earlier, the embodiment of Figs. 1-6 illustrates a composite diamond unit, best illustrated in Fig. 3 and therein generally designated 100, constituted of four individual diamonds (best seen in Fig. 1) assembled together by a common frame 101, such that the composite diamond unit 100 has a girdle 102; a crown 103 on one side of the girdle which is faceted as shown at 104 and is formed with a flat table 105; and a pavilion 106 at the opposite side of the girdle. Pavilion 106 illustrated in Fig. 3 is actually constituted of four pavilion segments 106a-106d, one for each of the individual diamonds identified as 110-140 in Fig. 1, with each pavilion segment facetted as shown at 107a-107d and terminating in a culet 108a- 108d, as will be described more particularly below.
Fig. 1 more particularly illustrates each of the individual diamonds 110-140, assembled together by common frame 101 to define the composite diamond unit 100 of Fig. 3. As shown in Fig. 1, each diamond unit includes a girdle segment 111—141, respectively, of the composite diamond unit 100; a crown segment 112-142, respectively, (Fig. 2) of the composite diamond unit 100; and the above-described pavilion segment 106a-106d. The crown segments 112-142 of the individual diamonds may be faceted. Each crown segment is formed with a flat upper surface 113-143 serving as the table segment of the composite diamond unit table 105 of Fig. 3.
As indicated earlier, each individual diamond 110-140 is of triangular configuration, each including three sides 114-116, 124-126, 134—136 and 144-146, respectively. The outer sides 114, 124, 134 and 144 together serve as the outer face of the composite diamond unit girdle and crown. The two inner sides 115, 116, 125, 135, 136 and 145, 146, respectively, are flat and smooth, and serve as inner faces in contact with each other in the composite diamond unit 100, as shown particularly in Fig. 2. As further shown in Fig. 1, each of the pavilion segments 106a-106d of the respective individual diamonds 110-140 is faceted on its inner surface 107a-107d, and terminates in its respective culet 107a-107d substantially centrally of this respective pavilion segment. As further seen in Figs. 3-4, the common frame 101 engages the outer faces 114, 124, 134, 144 of all the girdle segments 111, 121, 131, 141, to press the flat, smooth, inner faces of the individual diamonds 110, 120, 130, 140 into firm contact with each other such that the composite diamond unit 100 appears substantially seamless to the naked eye. The common frame is preferably made of gold, but may be made of other suitable materials, such as platinum.
It will thus be seen that the composite diamond unit 100 illustrated in Figs. 1-6 presents the appearance, at least to the naked eye, of being a single large diamond, rather than as a plurality of individual smaller diamonds. The composite diamond unit would therefore have substantially greater value than the four individual diamonds of which it is made. It will also be seen that the composite diamond unit 100 can be handled and mounted as a single unit, thereby substantially reducing the handling and mounting costs as compared to handling and mounting the four individual diamonds 110, 120, 130, 140 of the composite diamond unit 100. The Embodiment of Figs. 7-10
Figs. 7—10 illustrate a composite diamond unit, therein generally designated 200, also constituted of three individual diamonds 210, 220, 230 and 240, each of a triangular configuration. In this case, however, the four individual diamonds are arrayed in a triangular configuration in which three individual diamonds 210, 220 and 230 enclose the fourth individual diamond 240.
As seen particularly in Fig. 10, two of the outer sides, e.g., 214, 215, 224, 225 and 234, 235 of the three individual diamonds 210, 220, 230 have outer faces defining the outer face of the girdle and crown of the composite diamond unit 200, whereas the remaining side, 216, 226, and 236, respectively, has a flat, smooth, inner face each in contact with a flat, smooth, inner face 246a, 246b, 246c of the fourth individual diamond 240.
As further seen in Fig. 7, the common frame 201 (Fig. 7), which press the flat, smooth, inner faces of the individual diamonds into firm engagement with each other so as to produce a substantially seamless appearance to the naked eye, engages only the corners of the girdle segments of the individual diamonds, rather than the complete outer faces of the girdle segments as in the embodiment of Figs. 1-6.
In substantially all other respects, the composite diamond unit 200 illustrated in Figs. 7-10 is constructed in substantially the same manner as described above with respect to Figs. 1—6, and provides substantially the same advantages of that embodiment.
The Embodiment of Figs. 11-14
Figs. 11-14 illustrate the invention embodiment in a composite diamond unit 300 having a girdle of a rhombic configuration, consisting of two diamond units 310, 340 facing each other at their common bases. Thus, the composite diamond unit 300 illustrate in Figs. 11-14 is similar to composite diamond unit 200 illustrated in Figs. 7-10, except that the two individual diamonds 220, 230 in the composite diamond unit 200 have been omitted. Thus, the girdle and crown segments of the two outer sides 314, 315 of diamond 310, and the girdle and crown segments of the two outer sides 344, 345 of diamond 340, have outer faces which together serve as the outer face of the girdle and crown segments of the composite diamond unit 300; whereas the girdle and diamond segments of the third side of the two individual diamonds have flat, smooth, faces 316, 346 which are pressed into firm contact with each other so as to present a substantially seamless appearance to the naked eye. In this embodiment, the common frame 301 (Fig. 11), which presses the flat, smooth, faces 316, 346 of the girdle and crown segments into firm contact with each other engage, only the corners of the two triangular individual diamonds. In substantially all other respects, the composite diamond unit 300 illustrated in Figs. 11—16 is constructed, and provides the same advantages, as in the above- described embodiments. The Embodiment of Figs. 15-18
Figs. 15-18 illustrate a composite diamond unit, generally designated 400, having a girdle of trapezoidal configuration, constituted of three individual diamonds 410, 420, 430, arranged in a line, wherein the two end individual diamonds 410, 430 are in an upright position, whereas the middle individual diamond 420 is in an inverted position. In this case, the girdle and crowned segments of the two end individual diamonds 410, 430, include outer faces 414, 415 and 434, 435, respectively, serving as the outer face of the girdle and crown of the composite diamond unit 400, and a single inner face 416, 436, respectively, which is flat and smooth. On the other hand, the girdle and crowned segments of the middle individual diamond 420 includes but one outer face 424 which serves as the respective portion of the outer face of the girdle and crown of the composite diamond unit 400, and two inner faces 425, 426, which are flat and smooth and are brought into contact with the inner faces 416, 436, of the two end individual diamonds 410, 430. Also in this embodiment, the common frame 401 (Fig. 15), which presses the flat, smooth, inner faces of the three individual diamonds 410, 420, 430, into firm contact with each other, is applied only to the corners of the girdle segments of the three triangular individual diamonds.
In all other respects, the composite diamond unit 400 illustrated in Figs. 15-18 is of substantially the same construction, and provides substantially the same advantages, as in the above-described embodiments. The Embodiment of Figs. 19-22
The composite diamond unit illustrated in Figs. 19-22, and therein generally designated 500, includes a girdle and crown of hexagonal configuration, and is constituted of six individual diamonds 510-560, each of a triangular configuration. This embodiment is thus similar to that of Figs. 1-6, except that the girdle is hexagonal rather than square. The angles of the triangles also, of course, would be changed accordingly; that is, in the embodiment of Figs. 1-6, the angle at the apex would be 90° and those at the base would be 45°, whereas in the embodiment of Figs. 19-22, the angles at the apex, as well as the base, would be 60°. As in Fig. 1-6, the outer faces 514, 524, 534, 544, 554 and 564, respectively, serve together as the outer face of the girdle and crown of the composite diamond unit 500; whereas the two inner faces of each of the six individual diamonds are flat and smooth and are brought into firm contact with each other by the common frame 501. As shown in Fig. 19, the common frame 501 engages only the corners of the girdle segments of the six individual diamonds.
In all other respects, the construction and advantages of the composite diamond 500 illustrated in Figs. 19-22 are substantially the same as described above, particularly with respect to Figs. 1-6.
While the invention has been described above with respect to producing a composite diamond unit from a plurality of smaller individual diamonds, it will be appreciated that the invention could also be applied to produce other composite gemstones, such as emeralds or rubies. It will also be appreciated that while the invention has been described with respect to several preferred embodiments, such described embodiments are presented purely for illustrative purposes, and that many other variations and applications of the invention may be made.
