Cobalt: historical information. Cobalt was discovered by Georg Brandt at 1735 in Sweden. Origin of name: from the German word kobald meaning goblin or evil spirit. Minerals containing cobalt were of value to the early civilisations of Egypt and Mesopotamia for colouring glass deep blue.
When isolated, cobalt is well known for its deep blue color and has been used to provide this pigment in rings and jewelry since jewelry has been produced by man. Cobalt jewelry and cobalt rings are made primarily of cobalt, but more accurately they can be called Cobalt Chrome rings and Cobalt Chrome Jewelry.
