Abstract: Methods of making tungsten carbide-based annular jewelry rings including sinterable metal and/or ceramic powder materials compressed into a predetermined configuration and then sintered to form an annular jewelry ring to which softer precious metals, stones, crystals or other materials suitable for use in jewelry may be affixed. Such items of jewelry may have multiple facets and can be fabricated using various disclosed techniques and various combinations of materials.

Abstract: A novel technique for setting a multiplicity of precious stones such as diamonds into a unique setting to enhance the beauty and presentation of the multiplicity of set stones, with the technique including setting a center stone into a socket and having it held by a multiplicity of prongs, an outer series of small stones wherein each outer stone is respectively placed in a socket and is held in most designs by a pair of the same prongs which hold the center stone and is also held by a lower groove in the interior facing surface of the outer wall, and an intermediate series of stones which are placed in a respective socket and are held by a pair of the prongs which also retain the center stone and in most designs all of the smaller stones and are also retained by a groove in the interior facing surface of the outer wall, the intermediate series of stones also serving to retain the small series of stones.

Abstract: The present invention is a novel technique for setting a multiplicity of precious stones such as diamonds into a unique setting to enhance the beauty and presentation of the multiplicity of set stones, with the technique including setting a center stone held by small prongs, an outer series of stones wherein each outer stone is held by a pair of large prongs, and an intermediate series of stones held by the larger outer prongs which hold the small stones so that the intermediate stones partially cover the center stone and outer series of stones in a manner which conceals the way the outer stones are held.

Abstract: An integral ring which is contains at least 35 weight percent of a precious metal selected from the group consisting of silver and gold and has a porosity of less than 0.1 percent, a Vickers pyramidal hardness of at least about 120, and a tensile strength at least about 60,000 pounds per square inch. The ring has an inner diameter of from about 0.55 to about 0.93 inches, and outer diameter of from about 0.61 to about 1.09 inches, a thickness of from about 0.03 to about 0.08 inches, and a circumference of from about 1.7 to about 3.5 inches. Disposed about and extending around the entire outer surface of the ring is a first annular groove and a second, spaced apart annular groove, and at least 10 adjoining recessed areas are disposed between and communicate with these annular grooves. Each of the first annular groove and the second annular groove has a width of from about 0.01 to about 0.02 inches and a depth of from about 0.008 to about 0.018 inches.

Abstract: Wear resistant jewelry apparatus and method of making same wherein articles of jewelry are made from sinterable metal and/or ceramic powder materials compressed into a predetermined configuration and then sintered to form a blank from which a jewelry item may be made and to which softer precious metals, stones, crystals or other materials suitable for use in jewelry may be affixed. Such items of jewelry may have multiple facets and can be fabricated using various disclosed techniques and various combinations of materials.
