Abstract: A gem setting for use with a ring or other jewelry item with internal divisions having pluralities of stones in each division. Each division houses a different type or color of stone, such that the groupings of similar stones are preferably restricted to a particular region on the jewelry face. The divisions may take the form of a variety of shapes and geometric configurations.

Abstract: A solid wire of precious metal, such as gold, is drawn through a die which has a groove forming element disposed in a drawing channel located between the inlet and outlet of the die. The hollow wire exiting the die has an eccentric longitudinal open groove extending axially along the wire and embraced by a pair of tapered arms or cusps. The solid portion of the hollow wire is provided with a thick wall portion that is particularly adapted for forming diamond cut facets.

Abstract: A rope chain is made from hollow rectangular links having a trapezoidal cross section. The wider parallel surface of the trapezoid is the outer periphery of the shaped link and is the primary surface of the finished rope chain. The narrower parallel surface of the trapezoidal shape, having a channel which forms a longitudinal seam running around the inside of the link, is an inside surface of the finished rope chain and is not visible in a finished chain. The other two sides of the trapezoid converge in symmetrical relationship to the parallel surfaces, and include an angle that approximately equals 360.degree. divided by the number of links required to form a single cycle of links in a double helix, as viewed in an end view of the rope chain. Adjacent links abut, planar surface to planar surface, and form a close fitting circle with a smooth external surface for the rope chain.

Abstract: A rope chain is fabricated of links comprising an outer layer of a precious metal of a first color and an inner metal layer of a second color. The links are intertwined to form a rope chain. The links are faceted by diamond cutting techniques wherein the outer surface is partially sheared from the link to a depth such that an area of inner material of the second color becomes exposed and a two-tone link is produced. Facets having more than two color bands can also be produced.
