This invention relates generally to items of jewelry and more particularly to multifaceted gemstones and links securing the gemstones for assembly into pieces of jewelry.
Present day jewelry items, such as bracelets, necklaces, earrings and pendants, in the form of chains of precious metal (e.g., gold, silver or platinum) are well known. Such chains are formed of links of such metal. In order to enhance the aesthetic appeal of these jewelry items, designers have substituted gemstones for one or more of the links. These gemstones are set in conventional metal settings where the metal is substantially visible, especially when viewed from the side or back of the jewelry item. This detracts from the jewelry item as a whole as the item is unable to provide a complete gemstone look. Still further, the standard gemstones used in such items often lack radiance or brilliance thus further detracting from the aesthetic appeal of the jewelry piece.
Thus, there is a need to provide a multifaceted gemstone and link therefor for use in an item of jewelry which overcome the disadvantages of previously known jewelry items.
Accordingly, one aspect of the present invention is to provide a new multifaceted gemstone and link therefor for an item of jewelry which overcome the disadvantages of prior gemstones linked in jewelry items.
Another aspect of the present invention is to provide a new multifaceted gemstone and link therefor for an item of jewelry which can decrease the amount of metal required for the link.
Yet a further aspect of the present invention to provide a new multifaceted gemstone and link therefor for an item of jewelry which securely attaches the gemstone to the link.
A still further aspect of the present invention is to provide a new multifaceted gemstone and link therefor for an item of jewelry in that the gemstone, when mounted in the link, provides a complete look that emphasizes the gemstone and minimizes the metal of the link even when the combination is viewed from the rear and sides.
Another aspect of the present invention to provide a new multifaceted gemstone and link therefor for an item of jewelry which enables the jewelry item to have radiance and brilliance.
These and other aspects of the invention are achieved by providing a gemstone having a front and a back, the gemstone comprising a lower pavilion and an upper crown. The crown has a top surface and a pair of longitudinally opposed multifaceted sides that slope downwardly away from the top and towards the pavilion. The top surface of the crown has two laterally opposed top surface portions that are separated one from the other by a single horizontally directed linear straight peak that runs in a longitudinal direction between said sides. Each top surface portion slopes downwardly towards the front and back of the gemstone respectively. The pavilion has a bottom surface defined by at least one longitudinally opposed horizontally directed planar bottom portion.
First and second gemstones according to the present invention are used to form a jewelry element or assembly including at least one link. The link has a spacer for separating the gemstones one from the other in an opposed spaced relationship. The link further has a leaf member having first and second angularly directed leaf arms which form a v-configuration. The first leaf arm abuts at least a portion of the multifaceted side of the first gemstone and the second leaf arm abuts at least a portion of the multifaceted side of the second gemstone.
These and other aspects of the invention, together with features and advantages thereof, will become apparent from the following detailed description of several preferred embodiments, when taken in conjunction with the accompanying drawings.
Referring particularly to
Upper crown 22 has a front 24, a rear 26, a right side 28, a left side 30 and corners 32. The upper crown also defines a crown top surface 34 and a pair of longitudinally opposed multifaceted sides 36 that slope downwardly away from top surface 34 and towards pavilion 20. Crown top surface 34 has two laterally opposed top surface portions 38. Each top surface portion 38 has a central facet 40. Advantageously, central facet 40 is in the form of a triangle having sides 40a, 40b and 40c. Central facets 40 meet at sides 40c to form a straight generally horizontal linear peak 42 that runs in a longitudinal direction between multifaceted sides 36. One of surface portions 38 slopes downwardly in a lateral direction away from peak 42 towards front 24 of crown 22. The other of said surface portions 38 slopes downwardly in a lateral direction away from peak 42 towards rear 26 of the crown. Each top surface portion 38 also includes a pair of opposed side facets 44. Advantageously, side facets 44 are in the form of a trapezoid or a truncated triangle having sides 44a, 44b, 44c and 44d, with sides 44c and 44d parallel to each other. Side 40b of central facet 40 is common to one of the sides of side facet 44 and side 40a of central facet 40 is common to one of the sides of the other of side facet 44.
Longitudinally opposed multifaceted sides 36 include facets 46 in the form of narrow triangular top facets 46a, larger triangular side facets 46b and triangular front and rear facets 46c. When viewed from the front, facets 46 are stepped forming crown angles a, b and c. When viewed from the side, facets 46 form crown angle d.
Pavilion 20, which has a front 48a, a rear 48b and sides 48c and 48d, has a bottom surface 49 which is formed by a pair of longitudinally opposed horizontally directed planar bottom portions 50 and inwardly directed planar bottom portions 52 which are disposed between bottom portions 50. Bottom portions 52 are longitudinally slanted upwardly towards one another. Together bottom portions 52 form a pavilion angle e. Pavilion 20 may also include narrow rectangular facets 54 which are located along front 48a, rear 48b and sides 48c, 48d of the pavilion. Pavilion 20 also includes rounded corners 56. Corners 56 of pavilion 20 and corners 32 of crown 22 define gemstone corners 58 which may be formed with facets 60.
Gemstone 10 has a width W, a length L and a height H. Height H is formed of crown height H1 and pavilion height H2. Advantageously, height H is in the range of 30% to 70% of length L, while crown height H1 is in the range of 20% to 60% of length L. Likewise, advantageously crown angle a is in the range of 10° to 40°, crown angle b is in the range of 15° to 50°, crown angle c is in the range of 20° to 70°, crown angle d is in the range of 30° to 70° and pavilion angle e is in the range 100° to 160°.

The embodiment of
It will be appreciated that gemstone 10 has a cut which provides radiance and brilliance. This is achieved by crown top surface 34 and longitudinally opposed multifaceted sides 36 on crown 22 and/or by the inwardly directed bottom portions 52 on pavilion 20.
As shown in
Link 68 also includes a spacer 82 which functions to separate first gemstone 64 from second gemstone 66 in an opposed spaced relationship when the gemstones are connected to the link. Spacer 82 is generally rectangular in configuration having opposed parallel planar side walls 84 and a planar end wall 86 located between the side walls at one end of the spacer. The spacer also includes a v-shaped end wall 88 at the other end of the spacer which is complementary with the v-shaped configuration of leaf arms 78. Spacer 82 may include decorative gemstones 90 mounted in fittings 92 located at the top and at the bottom of the spacer. A passageway 94 which runs through the spacer at side walls 84 is also provided.
In order to fasten gemstones 64 and 66 to link 68, wire 70 is inserted through aperture 80 in leaf arm 78, through passageway 72 in first gemstone 64, through passageway 94 in spacer 82, through passageway 72 in second gemstone 66 and through passageway 80 in the other leaf arm 78 of the link. Advantageously, wire 70 may be soldered or otherwise connected to each leaf arm 78 and then finished so as not to detract from the appearance of assembly 62. For purposes of clarity, wire 70 is not shown in
Thus, the present invention provides a multifaceted gemstone and link assembly for an article of jewelry which decreases the amount of metal required for the link. The gemstone is also securely attached to the link preventing loss of the stone.
The gemstones may be varied by changing the rear, front and sides of the crown, while still retaining a common cut which provides radiance and brilliance of the stone. The cut is also configured so that the gemstone can be placed within the link.
While the present invention has been described with reference to several preferred embodiments, the invention should not be so limited. For example, while the multifaceted gemstones 64 and 66 are preferably secured to link 68 by wire 70 which runs through passageways in the gemstones and the link, the gemstones might secured to the link in other ways. For example, the gemstones might be glued to the link by applying glue to spacer sidewalls 84 and/or to leaf arm surfaces 78b. As another example, the bottom of pavilion 20 may be completely flat with inwardly directed bottom portions 52 eliminated or, if desired, inwardly directed bottom portions 52 may be “stepped” wherein the individual surfaces 52 are formed of a plurality of planar surfaces.
