The garnet family of silicate minerals all contain a +2 cation and a +3 cation.
Uvarovite is one of the rarest members of the garnet family. The +2 cation is
calcium and the +3 element is chromium. Uvarovite rarely forms single large
crystals. Instead it usually occurs as massive clusters of tiny green crystals.
