The Process To Create Tungsten Rings



The two biggest challenges to create these rings were shaping and finishing the super hard metal as well as devising a method to permanently bond bands of gold and platinum inside the Tungsten Carbide host ring.Tungsten Rings

The following is a simplified version of how the process works; Tungsten is processed with carbon and other elements and ground to a powder. The mixed powder is compressed into high pressure dies to form a ring blank The blank is sintered (fired) in an oxygen free furnace at over 1,300 degrees C, resulting in a solid Tungsten Carbide ring blank of extreme hardness. The rough blank goes through a 30 stage precision grinding process using exclusively diamond embedded grinding tools held in specially designed machinery. Versions containing platinum or gold inlaid sections are made by grinding a groove into the center of the hard metal ring and fuse the precious metal within the groove. The finishing process is unique in that diamond polishing compounds are used by skilled craftspeople and equipment to create a brilliant polish and luster never before achieved in the industry.
