07634 - Pink Cobaltoan Calcite Crystals on Matrix - Bou Azzer Mine (South Morocco) Edrioasteroids UnpublishedCalcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". The Cobaltoan calcite is a variety of calcite containing Co2+ replacing Ca, that's the reason for its pretty pink color.
