Druzy Cobalto-Calcite Pendant with Blue Persian Turquoise. A rare grouping of natural minerals with intense colors that are completely natural. I cut the pink calcite from a specimen from Congo, Africa. It has small pink sugar-like crystals that are colored by manganese. The blue translucent gemstone comes from Iran’s ancient turquoise mines. Hanging pendant with hinges and sterling silver with an 18”chain.
