ABSTRACT:
Methods are provided of making annular, tungsten-carbide jewelry articles including finger rings, bracelets, earrings, body jewelry, and the like. Advantageously, the methods include providing a tungsten-carbide based annular jewelry article having a desired surface profile and including an annular band that includes providing a mixture of two or more powdered materials of at least 50 weight percent to about 90 weight percent tungsten carbide to form the annular band of the article 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 band, compressing the powdered material mixture at a pressure sufficient to form an annular blank, and sintering the annular blank at a temperature sufficient to form the tungsten-carbide based annular jewelry article so as to be long wearing and virtually indestructible during normal use thereof.
