Tungsten in its pure form cannot be used in jewelry. Instead, it is formed into a metal, consisting of approximately 85% tungsten and 15% carbon, nickel or cobalt which is known as tungsten carbide. Because tungsten is very brittle, mixing it with carbon reduces this characteristic, making the metal more durable and easier to work with.
