(11) The present invention will be described with reference to certain embodiments and with reference to the above mentioned drawings, but such description is by way of example only and the invention is not limited thereto but only by the appended claims. Referring to FIG. 1, a typical stone 10 that may be utilized in accordance with the present invention is illustrated. Stone 10 is shown as round center diamond including a crown 11, a girdle 12, a pavilion 13, a table 14, and a culet 15, as is well known. The crown 11 is positioned above the girdle 12, while the pavilion 13 is positioned below the girdle 12. Stone 10 extends longitudinally along a center axis 16 from table 14 to culet 15. Stone 10 is shown to extend radially outward from center axis 16. Table 14 may be flat. The crown 11 may include upper facets 17 and pavilion 13 may include lower facets 18. Stone 10 may be a diamond or other precious or semi-precious gemstone as well as a synthetic stone. Stone 10 may preferably be a white diamond. It may further be possible to utilize stones 10 with color variances. While stone 10 is illustrated to have a round shape, it may not be limited to that shape. Other shapes, such as a square, rectangular, oval or cushion shape, may be used.

(12) Referring to FIGS. 2 through 4, a multiple stone setting 20 that enables a three-color change is illustrated in accordance with a first embodiment of the present invention. Multiple stone setting 20 includes three stones 21, 22, and 23, which may be identical with stone 10, as illustrated in FIG. 1. Accordingly, stone 21 may include a crown 211, a girdle 212, a pavilion 213, a table 214, and a culet 215, and may extend along a center axis 216. Accordingly, stone 22 may include a crown 221, a girdle 222, a pavilion 223, a table 224, and a culet 225, and may extend along a center axis 226. Accordingly, stone 23 may include a crown 231, a girdle 232, a pavilion 233, a table 234, and a culet 235, and may extend along a center axis 236.

(13) Each of the three stones 21, 22, and 23 is set on a plane surface 31, 32, and 33, respectively, with the tables 214, 224, and 234, respectively, facing outwards. The plane surfaces 31, 32, and 33 may be formed as a single piece, base 35, as shown in FIG. 4, and may be positioned relative to each other such that the stones 21, 22, and 23 may be set at a 90 angle between them, as shown in FIG. 3. Alternatively, plane surfaces 31, 32, and 33 may be separate pieces that may be joined to form base 35. As can be seen in FIG. 3, girdle 212 of the stone 21 is positioned perpendicular to girdle 222 of the stone 22 and accordingly center axis 216 of stone 21 is positioned perpendicular to center axis 226 of stone 22. As can be derived from FIG. 2, center axis 236 of stone 23 is positioned perpendicular to center axis 216 of stone 21 and to center axis 226 of stone 22. As illustrated in FIG. 4, plane surfaces 31, 32, and 33 may include apertures 36 that on one hand may save material and on the other hand may be used to receive and position culets 215, 225, and 235 of stones 21, 22, and 23, respectively. Alternatively, solid plane surfaces 31, 32, and 33 may be used. Plane surfaces 31, 32, and 33 and, therefore, base 35 may be made from gold, silver or any other suitable metal.

(14) Referring again to FIG. 3, stones 21, 22, and 23 may be secured in place on the plane surfaces 31, 32, and 33, respectively, by a plurality of prongs, center prong 41 and circumferential prongs 42. Center prong 41 extends vertically upward from the center 34 of base 35 and includes at its topmost end bearings for engaging the girdles 212, 222, and 232 of stones 21, 22, and 23, respectively. Alternatively, instead of using a single center prong 41, three separate prongs (not shown) may be utilized, each including a bearing for engaging one of the stones 21, 22 or 23. In addition to being secured by center prong 41, each of the stones 21, 22, and 23 is secured further by at least two circumferential prongs 42. Each circumferential prong 42 extends vertically upward from the circumference of base 35 and includes at its topmost end a bearing for engaging the girdle 212, 222 or 232 of one of the stones 21, 22 or 23, respectively. When set, the girdles 212, 222, and 232 of stone 21, 22, and 23, respectively, are oriented at a 45 angle in reference to the vertical extending prongs 41 and 42, as shown in FIG. 3. Setting of stones 21, 22, and 23 at a 90 angle with respect to each other may not be limited to using prongs 41 and 42 in connection with base 35. Other setting techniques, such as channel setting, nick setting, pave setting, or burnishing may be useful in some applications.

(15) When stone setting 20 is completed, each of the stones 21, 22, and 23 may display a different color due to the angle of inclination of the stones 21, 22, and 23. Thus, stone setting 20 displays three different colors concurrently. Furthermore, as the viewing angle changes, each of the displayed colors changes to a different color independent from the lighting conditions. Colors ranging from blue imitating sapphires to white imitating diamonds may be displayed.

(16) Referring now to FIG. 5, an exemplary utilization of the three-color changing stone setting 20 in accordance with one aspect of the present invention is illustrated. A plurality of stone settings 20 are shown joined in a circular jewel 50, such as a button, pin, ornament, brooch, or pendant. Alternatively, plurality of stone settings 20 may be joined in basically any shape desirable. Stone settings 20 may be arranged to form a color changing geometric pattern or to display, for example, a logo, a name or initials with changing viewing angles. In an alternate embodiment, two or more groups of joined stone settings 20 may be formed and a jewel may be created from these groups by tilting these groups of stone settings 20 relative to each other.

(17) Referring now to FIGS. 6 through 8, a multiple stone setting 70 that enables a two-color change is illustrated in accordance with a second embodiment of the present invention. Multiple stone setting 70 includes at least two stones 71 and 72, which may be identical with stone 10, illustrated in FIG. 1. Accordingly, stone 71 may include a crown 711, a girdle 712, a pavilion 713, a table 714, and a culet 715, and may extend along a center axis 716. Accordingly, stone 72 may include a crown 721, a girdle 722, a pavilion 723, a table 724, and a culet 725, and may extend along a center axis 726.

(18) Each of the two stones 71 and 72 is set on a plane surface 81 and 82, respectively, with the tables 714 and 724, respectively, facing outwards. The plane surfaces 81 and 82 may be formed as a single piece, base 85, as shown in FIG. 8 and may be positioned relative to each other such that the stones 71 and 72 may be set at a 90 angle between them, as shown in FIG. 7. Alternatively, plane surfaces 81 and 82 may be separate pieces that may be joined to form base 85. As can be seen in FIG. 7, table 714 of the stone 71 is positioned perpendicular to table 724 of the stone 72 and accordingly center axis 716 of stone 71 is positioned perpendicular to center axis 726 of stone 72. As illustrated in FIG. 8, plane surfaces 81 and 82 may include apertures 86 that on one hand may save material and on the other hand may be used to receive and position culets 715 and 725 of stones 71 and 72, respectively. Alternatively, solid plane surfaces 81 and 82 may be used. Plane surfaces 81 and 82 and, therefore, base 85 may be made from gold, silver or any other suitable metal.

(19) Referring again to FIGS. 6 and 7, stones 71 and 72 may be secured in place on the plane surfaces 81 and 82, respectively, by two center prongs 91 and 92 positioned proximate the middle of base 85 and two partial bezels 93 formed at opposite edges of base 85. Bezels 93 may be shaped like a wall including at the top end a bearing for engaging girdles 712 and 722. Each of the partial bezels 93 may be replaced by at least two prongs (not shown). Center prong 91 extends vertically upward from base 85 and includes at its topmost end a bearing for engaging the girdle 712 of stone 71. Center prong 92 extends vertically upward from base 85 at a distance from center prong 91 and includes at its topmost end a bearing for engaging the girdle 722 of stone 72. In addition to being secured by center prongs 91 and 92, each of the stones 71 and 72 may be further secured by partial bezel 93. When set, the girdles 712 and 722 of stone 71 and 72, respectively, are oriented at a 45 angle in reference to the vertical extending prongs 91 and 92, as shown in FIG. 7. Setting of stones 71 and 72 at a 90 angle with respect to each other may not be limited to using prongs 91 and 92 and partial bezels 93 in connection with base 85. Other setting techniques, such as prong setting, channel setting, nick setting, pave setting, or burnishing may be useful in some applications.

(20) When stone setting 70 is completed, each of the stones 71 and 72 may display a different color due to the angle of inclination of the stones 71 and 72. Thus, stone setting 70 displays two different colors concurrently. Furthermore, as the viewing angle changes, each of the displayed colors changes to a different color independently from the lighting conditions. Colors ranging from blue imitating sapphires to white imitating diamonds may be displayed.

(21) As illustrated in FIGS. 6 and 8, more than one pair of stones 71 and 72 may be used to form stone setting 70. In this case, a plurality of stones 71 may be placed in a row 710 and a plurality of stones 72 may be placed in a row 720. Stones 72 may be staggered relative to stones 71. The staggered rows 710 and 720 may include any desired number of stones 71 or stones 72, respectively. Also, any desired number of alternating rows 710 and 720 may be utilized. The stones 71 arranged in row 710 may display a first color while the stones arranged in row 720 may display a second color that is different from the first color. When the viewing angle of an observer is changed or the wearer of the stone setting 70 moves, each of the currently displayed colors changes to a different color. Furthermore, stone setting 70 may be utilized similar to stone setting 20 the create jewels as described above in connection with FIG. 5.

(22) By providing multiple stone settings 20 and 70 in accordance with exemplary embodiments of the present invention, three- and two-color changing surfaces may be created, respectively. The color and, therefore, the esthetic appearance of multiple stone settings 20 and 70 changes with the viewing angle of an observer due to the 90 angle of inclination of the set stones 21, 22, and 23 as well as 71 and 72, respectively. Accordingly, stone settings 20 and 70 provide not still surfaces but rather surfaces that acquire an autonomous entity by the movement of an observer or of the multiple stone settings 20 or 70 themselves. Stone settings 20 and 70 may be useful to create articles of jewelry as well as to enhance objects and designs of various natures.

(23) While the invention has been described by reference to various specific embodiments, it should be understood that numerous changes may be made within the spirit and scope of the inventive concepts described. Accordingly, it is intended that the invention not be limited to the described embodiments, but will have full scope defined by the language of the following claims.
