Druzy Cobalto-Calcite Pendant with Hemimorphite. 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 China and is of the rarer deep blue color. Hanging pendant with hinges and sterling silver with an 18”chain.
