Invisible Precious Stone Setting and Method Therefor

1. Field of the Invention

The present invention generally relates to the field of jewelry design and manufacture. More particularly, the present invention relates to the field of jewelry settings and method of mounting precious stones therein, where the jewelry setting is substantially invisible.

2. Description of the Prior Art

Specifically, articles of jewelry in which multiple precious stones are mounted flush to one another with no spaces or setting material being visible, are very attractive and highly desirable. To invisibly mount a large number of princess cut diamonds (square shaped diamonds), one approach of the prior art is to notch the diamonds and to mount them in a setting which has two or more parallel flat-surfaced walls, with metallic projections, e.g., prongs or the like, protruding from the walls for interengaging the notches. Typically, these walls define channels in which the princess cut diamonds are set abutting one another in accordance with the invisible mounting method of the prior art. The disadvantage with this prior art invisible mounting method is that it is basically only suitable for princess cut diamonds but not for circular shaped diamonds.

Another approach of the prior art is to have sharp edges point upwardly from opposed facets of the diamonds. Because of the sharp edges, it is possible to push the diamonds down and secure the same in place between walls of the setting. The upwardly pointed edges tend to bite into the flat walls, such that an attempt to pull the diamonds out causes the upwardly pointed edges to bite deeper into the walls, thereby more securely fixing the diamond in place. The disadvantage with this prior art invisible mounting method is that it is also basically only suitable for princess cut diamonds but not for circular shaped diamonds.

The Tessler Patent discloses jewelry wherein relatively large stones are mounted higher than relatively small stones and a method of manufacturing this item.

It is highly desirable to have a very attractive and also very efficient design and construction of an article of jewelry, such as a ring or pendent, where a plurality of precious stones, such as round brilliant full cut diamonds are mounted flush to one another and with no gap between the diamonds to make the setting material invisible to the naked eye, thereby providing a uniform impression. It is further desirable to provide a method of mounting round precious stones, such as circular shaped diamonds, where the diamonds are more securely fixed within the setting, while the setting is substantially invisible.

The present invention is a method of and an apparatus for mounting two or more rows of round shaped precious stones, such as circular shaped diamonds, in a side-by-side manner on an article of jewelry, such as a ring, such that the precious stones are flush to one another without spaces or mounting material being visible therebetween.

In one preferred embodiment, the present invention method and apparatus is applied to a ring having three rows of circular shaped precious stones supported on a generally ring shaped mounting structure. The mounting structure includes a closed cavity, two spaced apart zig-zag parallel interior sidewalls extending the length of the cavity, and two opposite straight parallel exterior sidewalls, where the walls form three elongated parallel channels each receiving one of the rows of precious stones. Each interior sidewall has alternating inward and outward facing protruding projections or flanges extending into the channels, and each exterior sidewall has multiple spaced apart small inward-facing recesses or dents. The alternating inward-facing protruding projections of one zig-zag interior sidewall are respectively paired with the alternating inward-facing protruding projections of the other zig-zag interior sidewall in a spaced apart and oppositely facing relationship. The alternating outward-facing protruding projections of each zig-zag interior sidewall are paired with the small inward-facing recesses of the respective adjacent exterior sidewall and also in a spaced apart and oppositely facing relationship. The channels of the mounting structure are open at the top, but the alternating facing protruding flanges restrict the opening so that the precious stones cannot be directly inserted down into the channels without the application of a force.

The precious stones are formed with cutout grooves extending along both or either side of each precious stone. The stones of the middle row have cutout grooves on both sides of each stone. The stones of the two outside rows have a cutout groove on only one side of each stone. The precious stones of the middle row are secured and held between the two zig-zag interior sidewalls, where the paired alternating inward-facing protruding flanges are engaged with the two cutout grooves at both sides of each precious stone. The precious stones of each outside row are secured and held between an interior sidewall and an adjacent exterior sidewall, where the alternating outward-facing protruding projections of the interior sidewall are engaged with the cutout groove at one side of each stone, and the other side of the diamond without any cutout groove is engaged with the inward-facing dent of the adjacent exterior sidewall. What is unique about the method and apparatus of the present invention is that it can be used with circular shaped diamonds instead of square shaped diamonds as taught in the prior art. In addition, when the circular shaped diamonds are mounted within the cavity, the zig-zag interior sidewalls will be entirely concealed by the diamonds and no gaps between the diamonds are present. The mounting structure also provides a uniform top surface for the circular shaped diamonds, where the diamonds are flush with one another.

It is therefore an object of the present invention to provide a method and apparatus for mounting precious stones, particularly circular shaped diamonds, so that there are no spaces between the diamonds and such that the mounting material under the diamonds is invisible.

It is an additional object of the present invention to provide an apparatus which utilizes zig-zag interior sidewalls, where each zig-zag sidewall has alternating inward and outward facing protruding projections, and exterior sidewalls having multiple spaced apart small inward facing recesses for securing multiple rows of diamonds therebetween.

It is a further object of the present invention to provide a method of preparing precious stones, such as circular shaped diamonds, where the circular shaped diamonds have either one or two opposite cutout grooves.

It is still a further object of the present invention to provide a method of preparing precious stones, such as circular shaped diamonds, where the circular shaped diamonds have either one or two opposite V-shaped cutout grooves.

It is another object of the present invention to provide an apparatus which utilizes zig-zag interior sidewalls, where each zig-zag sidewall has alternating inward and outward protruding V-shaped projections, and exterior sidewalls having multiple spaced apart small inward facing recesses for securing multiple rows of diamonds therebetween.

The present invention is thus directed to increasing the aesthetic appeal of articles of jewelry which are composed of precious stones by decreasing impediments to light transmission between adjacent precious stones, and diamonds will also be more secured in the mounting.

Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.

Referring to FIG. 1, there is depicted at 10 a top plan view of a finished product of the present invention method and apparatus for mounting and setting two or more rows of precious stones, such as circular shaped diamonds, in an article of jewelry 14, such as a ring, such that the precious stones are flush to one another without spaces or mounting material being visible therebetween. The rows of precious stones include a middle row of diamonds 12 and two outside rows of diamonds 13.

Referring to FIGS. 8 and 9, there is depicted one of the plurality of diamonds 12 for the middle row in accordance with the present invention. Because the diamonds 12 are constructed the same, only one will be described in detail below. The diamond 12 is typically circular shaped and has an upper table 50 at the upper end thereof, a crown 52, a girdle 54, a lower cone shaped pavilion 56, and a culet 58 at the bottom of the cone shaped pavilion 56. In accordance with the approach of the present invention, the diamond 12 is provided with two opposite cutout grooves 60 and 62 which are formed with the aid of an exceedingly thin, disk-shaped saw (not shown) which rotates at a very high speed and which is held horizontally parallel to the table 50. The saw is moved along the directions indicated by the arrows toward the diamond to form the grooves 60 and 62. Consequently, the size of the grooves may vary from diamond to diamond.

Referring to FIG. 10, there is depicted one of the plurality of diamonds 13 for the two outside rows in accordance with the present invention. Because the diamonds 13 are constructed the same as previously described above, the description thereof will not be repeated. The diamond 13 is typically the same as the diamond 12 shown in FIGS. 8 and 9 except that the diamond 13 only has one cutout groove 63 along one side of the diamond.

Referring to FIGS. 2, 3 and 4, there is shown the ring 14 which has a mounting structure 16. The mounting structure 16 includes a base portion 18, two opposite end walls 20 and 21, and two opposite exterior sidewalls 22 and 23. The walls 20, 21, 22, and 23 are integrally formed with the base portion 18 and extend upwardly from the base portion 18 to form a generally rectangular shaped cavity 24. Each exterior sidewall has a plurality of spaced apart small inward-facing recesses or dents 26 formed therein (see FIGS. 4 and 6).

Two spaced apart zig-zag interior sidewalls 28 and 30 are provided with the mounting structure 16. The two interior sidewalls 28 and 30 are mounted within the cavity 24, and integrally formed with the base portion 18 and the two opposite end walls 20 and 21. The two interior sidewalls 28 and 30 extend upwardly from the base portion to form three generally longitudinal channels 32, 34 and 36, where each channel receives therein one row of precious stones 12 and 13. The zig-zag sidewalls 28 and 30 in accordance with the present invention preferably extend longitudinally in the circumferential direction of the ring 14.

From the left of FIG. 2 where the portion of the zig-zag interior sidewall 30 is enclosed by dashed lines, each zig-zag sidewall is constructed with a first inward-facing longitudinal section 64 connected to an outward-facing bend section 65 which in turn connects to an outward-facing longitudinal section 66 which in turn connects to an inward-facing bend section 67, and etc., where the sections repeat itself starting with the inward-facing longitudinal section 64. A plurality of laterally alternating inward and outward facing protruding projections or flanges 38 and 39 respectively are integrally form on the longitudinal sections of the interior sidewalls 28 and 30, and located adjacent to the upper free ends. These alternating inward and outward facing projections 38 and 39 extend into the channels 32, 34 and 36 respectively (see FIGS. 3, 4, 5 and 6). In addition, these alternating inward and outward facing projections 38 and 39 may extend only a small portion on the longitudinal section.

Referring to FIG. 3, the alternating inward-facing protruding projections 38 of one zig-zag interior sidewall 28 are paired with the alternating inward-facing protruding projections 38 of the other zig-zag interior sidewall 30 in a spaced apart and oppositely facing relationship respectively. Referring to FIG. 4, the alternating outward-facing protruding projections 39 of each zig-zag interior sidewall are paired with the small inward-facing recesses 26 of a respective adjacent exterior sidewall and also in a spaced apart and oppositely facing relationship.

As may be appreciated from FIGS. 5 and 6, the distance between the zig-zag interior sidewalls 28 and 30 is slightly smaller than the outer diameter of the diamond 12. The distance between one of the exterior sidewalls and one of the interior sidewalls is also slightly smaller than the outer diameter of the outside diamond 13. The thickness of the interior sidewalls 28 and 30 is such that when the diamonds are respectively inserted into the channels 32, 34 and 36, they are disposed very closely and, ideally, perfectly abutting one another as shown in FIG. 1. Referring to FIGS. 5 and 8, there is depicted one of the plurality of diamonds 12 for the middle row, which is mounted between the two zig-zag interior sidewalls 28 and 30. The diamond 12 is forced between the two zig-zag interior sidewalls 28 and 30, such that the paired alternating inward-facing protruding projections 38 are inserted and engaged with the two cutout grooves 60 and 62 at both sides of each diamond 12. Referring to FIG. 7, after the diamond is set therein, the paired alternating inward-facing protruding projections 38 of the zig-zag sidewalls 28 and 30 may be respectively forced inwardly to secure the diamond from moving in the transverse direction. In addition, the angled or inclined sections 41 of the zig-zag interior sidewalls 28 and 30 are tapped inwardly toward the diamond (shown by arrows) to create bulges at four locations such that these bulges prevent the diamond from moving in the longitudinal direction. Alternatively, small stopper bars or blocks may be placed at the locations indicated by the arrows, which can be tapped towards the diamond after the diamond is set to prevent the movement of the diamond.

Referring to FIGS. 4, 6 and 10, there is depicted two of the diamonds 13 for the two outside rows. The diamond 13 is secured and held between an interior sidewall and an adjacent exterior sidewall, where the outward-facing protruding projection 39 of the interior sidewall is engaged with the cutout groove 63 at one side of each diamond 13, and the other side 25 of the diamond 13 without any cutout groove is engaged with the inward-facing dent 26 of the adjacent exterior sidewall. After the diamond is set therein, the alternating outward-facing protruding projection 39 may be forced inwardly toward the diamond to secure the diamond in the transverse direction. In addition, the bend sections 65 and 67 of the zig-zag interior sidewalls 28 and 30 are tapped inwardly toward the diamond to create bulges at two opposite locations such that these bulges prevent the diamond from moving in the longitudinal direction (see FIG. 2).

Referring again to FIG. 2, the reference numeral 40 designates a plurality of spaced apart apertures on the base portion 18, which typically are circular shaped, and which are formed in the mounting structure 16 directly below the culet 58 of the diamonds 12 and 13, to admit light into the channels 32, 34 and 36, and thus enhance the lustre and light dispersing properties of the diamonds.

The present invention has been described in connection with a setting for a ring which produces a matrix of invisibly mounted diamonds. It will be appreciated that the method and apparatus of the present invention is not limited to the ring application as illustrated in FIGS. 1 and 2. It is emphasized that while the ring application is the preferred embodiment, it is also within the spirit and scope of the present invention to utilize the application for other jewelry articles including but not limited to necklaces and bracelets, bangels, earrings, and pendents. An example of such an application is a heart shaped pendent structure 110 as shown in FIG. 11. The mounting of the diamonds is the same as in the preceding embodiment, and the description thereof will not be repeated.

The present invention conforms to conventional forms of manufacture or any other conventional way known to one skilled in the art.

The present invention has many advantageous features including: (a) mounting of circular shaped precious stones; (b) mounting material being invisible; and (c) the diamonds having an uniform surface and are flush to one another and with no gap between the diamonds; and (d) more secured setting of diamonds.

Referring to FIG. 12, there is depicted an alternative embodiment of the present invention method and apparatus for mounting two or more rows of precious stones, such as circular shaped diamonds, in an article of jewelry 114, such as a ring, such that the precious stones are flush to one another without spaces or mounting material being visible.

Referring to FIG. 17, there is depicted a top plan view of one of the plurality of diamonds 112 in accordance with the present invention. Because the diamonds 112 are the same in the preceding embodiment, the description thereof will not be repeated, and only the modified part will be described in detailed. In this embodiment, cutout grooves 160 and 162 are generally V-shaped which are shown in dashed lines.

Referring to FIGS. 12 and 13, there is shown the ring 114 which has a mounting structure 116. The mounting structure 116 includes a base portion 118, two opposite end walls 120 and 121, and two opposite exterior sidewalls 122 and 123. The walls 120, 121, 122, and 123 are integrally formed with the base portion 118 and extend upwardly from the base portion 118 to form a generally rectangular shaped cavity 124.

Four spaced apart zig-zag interior sidewalls 128, 129, 130 and 131 are provided with the mounting structure 116. The zig-zag interior sidewalls 128, 129, 130 and 131 are mounted within the cavity 124, and integrally formed with the base portion 118 and the two opposite end walls 120 and 121. The zig-zag interior sidewalls extend upwardly from the base portion 118 to form three generally longitudinal channels 132, 134 and 136, where each channel receives a row of precious stones 112, all being flush with one another. The zig-zag interior sidewalls in accordance with the present invention preferably extend longitudinally in the circumferential direction of the ring 114.

From the left of FIG. 12, each zig-zag sidewall is constructed by a first outward bend section 165 which in turn connects to a second inward bend section 167 and etc., where the sections repeat itself starting with the outward bend section 165. Each bend section has protruding projections or flanges 138 and 139 which are integrally form thereto or it may only have one protruding projection 138. These protruding projections 138 and 139 are located adjacent to the upper free ends. These projections 138 and 139 extend into the channels 132, 134 and 136 respectively (see FIGS. 13). In addition, the projections 138 and 139 may extend only a small portion of the bend section.

Referring to FIGS. 13 and 17, the diamonds 112 are forced between two adjacent zig-zag interior sidewalls such that the protruding projections 138 and 139 are respectively inserted and engaged within the two V-shaped cutout grooves 160 and 162 of the diamond 112. After the diamond is set therein, the protruding projections 138 and 139 of the two adjacent zig-zag interior sidewalls may be respectively forced inwardly to secure the diamond from moving in the transverse and longitudinal directions.

The reference numeral 140 designates a plurality of spaced apart apertures on the base portion 118, which typically are circular shaped, and which are formed in the mounting structure 116 directly below the culet of the diamonds 112, to admit light into the channels 132, 134 and 136, and thus enhance the lustre and light dispersing properties of the diamonds.

Referring to FIG. 14, there is depicted a top plan view of another alternative embodiment of the present invention method and apparatus for mounting two or more rows of precious stones, such as circular shaped diamonds, in an article of jewelry 214, such as a ring, such that the precious stones are flush to one another without spaces or mounting material being visible. It assembles and functions the same as described in FIGS. 12 and 13, except that the four zig-zag interior sidewalls 128, 129, 130 and 131 are substituted with only two space apart zig-zag interior sidewalls 229 and 230. The circular shaped diamond 112 shown in FIG. 17 is also used in this embodiment, and the description thereof will be repeated.

Referring to FIGS. 14 and 17, the diamonds 112 are formed with two opposite V-shaped cutout grooves on both or either side of each diamond. The diamonds of the middle row have V-shaped cutout grooves 160 and 162 on both sides of each stone. The diamonds of the two outside rows have only one V-shaped cutout groove on only one side of each diamond.

Referring to FIGS. 15 and 16, the diamonds 112 in the middle row are forced between the two interior zig-zag interior sidewalls 229 and 230, such that the protruding projections 238 are respectively inserted and engaged within the two V-shaped cutout grooves 160 and 162 of each diamond 112. After the diamond is set therein, the protruding projection 238 of the zig-zag sidewalls 229 and 230 may be respectively forced inwardly to secure the diamond thereto.

Referring to FIG. 15, the diamonds for the two outside rows has only one V-shaped cutout groove instead of two V-shaped cutout grooves as shown in FIG. 17. It will appreciated that the mounting of the outside diamond is the same as described in FIGS. 1 through 11, except that in this embodiment V-shaped cutout groove is utilized instead of longitudinal cutout grooves. The outside diamond is mounted between a zig-zag interior sidewall and an adjacent exterior sidewall. The other side 225 of the diamond 112 without the V-shaped cutout groove 160 is inserted into and engaged with the inward-facing dent 226 of the exterior sidewall, while the protruding projection 239 is inserted into and engaged within the V-shaped cutout groove 160 of the diamond 112. After the diamond is set therein, the protruding projection 239 may be forced inwardly to secure the diamond thereto.

Referring to FIGS. 18 and 19, there are shown two possible alternative embodiments of the present invention. FIG. 18 shows two rows of circular diamonds mounted in a setting which has one middle zig-zag wall between two outer walls. FIG. 19 shows a row of circular diamonds mounted by utilizing a one-sided zig-zag wall together with a row of princess cut diamonds. The zig-zag wall on the circular diamond size has projections, while on the princess cut diamond side, it is straight with a straight groove.
