As used herein, “bonded” includes, but is not limited to, welding, soldering and adhering.
With reference to
The gemstone 130 may be any suitable or desired gemstone. Suitable gemstones include, for example, diamonds, emeralds, rubies, sapphires, or cubic zirconia. According to certain preferred embodiments, the gemstone 130 is cut so as to include a tapered pavilion or base portion 132 (for example, having a generally inverted conical shape as shown), a tapered crown or top portion 134 extending upwardly from the base portion 132, and a crest or girdle 136 located at the interface between the base portion 132 and the crown 134. Suitable stone shapes or cuts may include those commonly referred to as round, princess cut, pear shape, oval, marquise, radiant, heart shape, emerald cut or triangular cut.
The base member 110 may be formed of any suitable material. For example, the base member 110 may be formed of gold, silver, platinum, or any other metal suitable for manufacturing jewelry. The base member 110 has an upper end 110A and a lower end 110B. The base member 110 includes an upper ring 112 at the upper end 110A. A plurality of legs 114 are distributed (for example, equidistantly) about the ring 112 and each has an upper end secured to the ring 112 (for example, by welding or soldering), and a lower end joined (for example, by welding or soldering) to the lower ends of the other legs 114 at a point or apex 116 at the lower end 110B. The legs 114 are arranged such that the base member 110 tapers from the upper end 110A to the lower end 110B and has a conical outer shape or profile. According to some preferred embodiments, the base member 110 is tapered to form an included angle B (
The post 105 is secured to the point 116, for example, by welding or soldering. The gemstone mount assembly 101 may be used in other types of jewelry pieces by likewise or similarly securing the base member 110 to a ring band, pendant ring or the like. According to some other embodiments, a ring band, pendant ring, earring post or the like is secured, for example, by welding or soldering to the bezel member 140.
According to some preferred embodiments and as shown, the bezel member 140 is a continuous, endless ring. The bezel member 140 may be formed of any suitable material. Suitable materials may include those discussed above for the base member 110. The bezel member 140 may have a rounded or otherwise attractive outer contour as shown. According to some preferred embodiments, the width W1 (
The securement and cooperative engagement between the base member 110, the gemstone 130 and the bezel member 140 will be better appreciated from the discussion of methods for assembling the jewelry piece 100 as set forth below. The gemstone 130 is positioned between the base member 110 and the bezel member 140. For example, the gemstone 130 may be placed in the base member 110 such that the base portion 132 is received in the cavity 121. According to some preferred embodiments, the outer diameter D1 of the ring 112 is less than the outer diameter of the girdle 136 so that the upper part of the base portion 132 rests on the ring 112 and the girdle 136 is disposed above the ring 112. According to certain preferred embodiments of the present invention, the outer diameter D1 is between about 0 and 1 mm less than the outer diameter of the girdle 136. According to certain preferred embodiments-of the present invention, the cavity 121 is sized and shaped to fully receive the gemstone 130 to the point of engagement with the ring 112 without interference between the base portion 132 and the legs 114. For this purpose, the base member 110 may taper at a lesser angle than the base portion 132. According to some embodiments of the present invention, the angle A (
The bezel member 140 is then placed over the base member 110 such that the crown 134 is received through the opening 148. The diameter D2 of the opening 142 is greater than the diameter of the girdle 136 while the diameter D3 of the opening 142 is less than the outer diameter of the girdle 136. Accordingly, the shoulder 147 surrounds and overlaps an annular portion of the crown 134 to thereby capture the gemstone 130 between the base member 110 and the bezel member 140. More particularly, in accordance with certain preferred embodiments and as shown, the girdle 136 is captured between the shoulder 147 and the ring 112. According to certain preferred embodiments, the diameter D2 is between about 0.001 mm and 1 mm greater than the diameter of the girdle 136. According to certain preferred embodiments, the diameter D3 is at least about 0.25 mm less than the outer diameter of the girdle 136.
While the above-described method includes mounting the gemstone in the base member 110 and thereafter mounting the bezel member 140 on the base member 110, the gemstone may alternatively be mounted on the bezel member 140 first and the base member 110 then mounted on the bezel member 140. Alternatively, the gemstone may be mounted between and in the base member 110 and the bezel member 140 simultaneously with the mounting of the base member 110 and the bezel member 140 to one another.
According to some embodiments, the diameter D2 of the lower wall 144 is less than the outer diameter D1 of the ring 112. The bezel member 140 is forced or press-fitted onto the ring 112 so that the ring 112 and the wall 144 form an interference or friction fit therebetween. This friction fit may serve to hold the components 110, 130, 140 together for ease in executing subsequent assembly steps. Additionally, the friction fit may serve to assist in the permanent securement of the bezel member 140 to the base member 110. According to certain preferred embodiments, the diameter D2 is between about 0.001 and 0.1 mm less than the diameter D1.
After the base member 110, the gemstone 130 and the bezel member 140 have been assembled as described above, the base member 110 and the bezel member 140 are welded together. More particularly, the wall 144 is welded to the ring 112 such that the bezel member 140 and the base member 110 are immovably fixed or coupled to one another. This welding step is facilitated by the overlap between the components to be welded, providing for secure weld locations. The welds may be continuous or spot welds. According to certain preferred embodiments, the bezel member 140 is laser welded to the base member 110.
The methods according to the present invention may provide certain further advantages. Because it is not necessary to bend prongs or the like to secure the gemstone 130 within the gemstone mount assembly 101, the associated high heat (e.g., using a torch) and metal work are not required and heat-sensitive and pressure-sensitive stones can be used without elevated risk of damage or special care. The gemstone mount assembly 101 can be quickly assembled without requiring significant skill. This is particularly facilitated by the friction fit or interlock between the ring 112 and the bezel member 140.
The gemstone mount assembly 101 may be particularly advantageous in that the gemstone mount assembly 101 may be formed so as to be relatively light in weight. The gemstone mount assembly 101 and the jewelry piece 100 provide an overall aesthetically pleasing appearance. The bezel member 140 is unobtrusive and may serve as a decorative element. According to some preferred embodiments, the bezel member 140 forms a peripheral edge or flange surrounding the gemstone mount assembly 101. The shape of the base member 110 can be formed so as to complement the gemstone 130.
As noted below, the gemstone mount assembly 101 including the tapered base member 110 is particularly well suited for use in an earring. With reference to

Various of the features and aspects described above may be combined. For example, the gemstone mount assembly 101 may be modified to include a pyramidal base member and a square bezel ring as in the gemstone mount assembly 501. The embossments and cutouts may be formed in base member cups of various shapes (e.g., pyramidal, conical, oval, etc.). The bezel members and base members of the various gemstone mounting assemblies of the present invention can be bonded by any suitable means such as welding, soldering and adhering. However, according to certain embodiments, welding is preferred because it eliminates the presence of solder or adhesive that may adversely affect the appearance of the mount and/or the gemstone.
