Facts About Tungsten Ring

Tungsten rings are a very durable alternative to the traditonal gold or silver rings. These jewelry pieces can more accurately be called tungsten carbide rings, however. This compound is created by mixing powered tungsten and powdered black carbon and heating them to a very high temperature in the presence of hydrogen. Originally developed by Osram, a German electric bulb company in the early 1920s, this process to make tungsten carbide has generally been used to create industrial products. The strength of tungsten carbide materials lends itself well to long-wear jewelry, such as rings.
