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.
Claims18
A method of making a finger ring which comprises:
- providing an annular finger ring that defines an aperture configured and dimensioned to receive a person's finger and which comprises a sintered mixture of at least two powdered materials comprising predominantly tungsten carbide and a relatively lesser amount of a metal binder component, with the annular ring having at least one external facet;
- and
- finishing the at least one external facet to a predetermined shape to provide a finish to a portion of the finger ring, with the sintered mixture retaining the predetermined shape and finish for the lifetime of the jewelry ring.
A method of making a jewelry article which comprises:
- providing an annular tungsten carbide-based ring comprising a sintered material comprising predominantly tungsten carbide and a metal binder component in a relatively lesser amount, and having an outer surface and a depression disposed circumferentially in its outer surface;
- providing an elongated decorative metal insert sized and dimensioned to at least partially fit into the depression;
- and
- disposing the elongated decorative metal insert at least partially into the depression to cause the metal insert to at least substantially fill the depression so as to form the jewelry article,
- wherein the annular tungsten carbide-based ring is sufficiently hard to avoid being deformed after being provided.
