Scandium is never found as the free metal. Scandium is apparently a much more abundant element in the sun and certain stars than on earth. However it is widely distributed being present in very small amounts in nearly a thousand different minerals. The blue colour of beryl (aquamarine variety) is said to be due to scandium.
