  • Patent number: 5488839
    Abstract: A jewelry setting for translucent, diamond baguettes in which the position of the baguette gemstones are interleaved with metallic reproductions of the gemstones to create the illusion of uniformly mounted diamond baguettes. The geometric configuration of a baguette or tapered baguette gemstone is recreated in metal which is the same color as that of the jewelry setting. The baguette gemstones are mounted in the setting adjacent interleaved metallic baguettes. Light refracted through the translucent baguette gemstone will be reflected from the gemstone facets, the surface of the jewelry setting and from reflective facets of the metallic baguette. When combined from the light reflected directly from the crown facets of the metallic baguette, an illusion of uniformly adjacent diamond baguettes is created.

  • Patent number: 5218839
    Abstract: A jewelry setting for a gemstone which provides the illusion or otherwise simulates the appearance of a larger gemstone. The setting comprises a collar having an axial, cylindrical bore disposed therethrough. A V-shaped cut is formed in the surface of the cylindrical bore perpendicular to the longitudinal axis of the collar. The collar is adapted to secure the gemstone for mounting. The apex of the V-shaped cut defines a circle substantially equivalent to the girdle of the gemstone and lies in a plane which is perpendicular to the longitudinal axis of the collar. The intersecting surfaces of the V-shaped cut are adapted to be adjacent a portion of the pavilion and crown of the gemstone. The upper surface of the collar uniformly circumscribes a segment of the crown of the gemstone and thereby permits display of the gemstone table and the uncovered portion of the crown.
