Cobalt is alloyed with chrome for a bright silvery finished metal and is markedly harder and more durable than gold, but possesses a similar malleability and can be finished in the same fashion. Cobalt rings require minimal care, are highly durable, are biocompatible, and can be worn under nearly any condition or environment. Josef Elias offers a range of Cobalt designs that are affordable yet maintain a sense of understated sophistication.
