Cobaltoan Calcite also known as Cobalt Calcite, cobalto calcite, or cobaltocalcite. The physical properties of cobaltoan calcite are the same as those of calcite. It crystallizes in the hexagonal (trigonal) system, usually as rhombohedrons, scalenohedrons, and prisms. It has a Mohs hardness of 3.0. It is an uncommon variety of Calcite that has been infused with small amounts of the accessory element cobalt that imparts a distinctive, bright, pink-magenta color. Usually, the amount of Cobalt within determines how pink the stone is. You’ll most likely see this mineral in tiny druzy clusters over matrix.
