Patent ID: 6993842

Claim:
A method of providing a tungsten-carbide based annular jewelry article having a desired surface profile and including an annular ring that defines an aperture adapted and configured to receive a body part, which comprises: providing a mixture of two or more powdered materials which comprises tungsten carbide material in a predominant amount sufficient to form the annular ring into a pressure mold having a cavity of predetermined annular configuration and sized formed therein, the size of the mold being greater than the final size of the annular ring; compressing the powdered material mixture at a pressure sufficient to form the annular ring into an annular blank which has the aperture adapted and configured to receive a body part; sintering the annular blank at a temperature sufficient to form the tungsten-carbide based annular ring so as to be long wearing and virtually indestructible during normal use thereof; providing at least one depression that extends into, and at least substantially around the circumference of, an outer surface of the annular ring; and introducing molten metal into at least a portion of the depression so that it will harden within the depression to provide the annular jewelry article.
