Metallic Gems

Many gems are metallic minerals containing elemental metals as the main part of their chemistry. These gems contain elemental metals such as copper, cobalt, iron, lead, nickel, titanium and zinc. Others, such as gold and silver, are native elements. Some gems, such as Campbellite and Mohawkite, are a conglomeration (congl.) of several metals and other minerals and are not IMA recognized names.
