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.
Claims3
A finger ring comprising:
- an annular body having an axis of symmetry and inner and outer circumferences, and made of material selected from the group consisting of sintered metals and ceramics, said body including:
- a first frusto-conically shaped facet extending around the outer circumference of said body, and forming a first outer surface of said body proximate a first axial extremity thereof;
- a second frusto-conically shaped facet extending around the outer circumference of said body, and forming a second outer surface of said body proximate a second axial extremity thereof opposite said first axial extremity,
- a cylindrically shaped third facet extending around the outer circumference of said body, and forming a third outer surface of said body disposed between said first and second facets, said third facet having at least one annular groove formed therein and an outer diameter,
- a precious metal disposed within said groove, an outer surface of said precious metal lying within the outer diameter of said third surface such that said third surface protects said precious metal from wear,
- a fourth frusto-conically shaped facet extending around the inner circumference of said body, and forming a first inner surface of said body proximate said first axial extremity, and
- a fifth frusto-conically shaped facet extending around the inner circumference of said body, and forming a second inner surface-of said body proximate said second axial extremity,
- said first, second, fourth and fifth facets having surface angles within the range of from 1.degree. to 40.degree. relative to said axis of symmetry and being ground and polished to a mirror finish.
