07634 - Pink Cobaltoan Calcite Crystals on Matrix - Bou Azzer Mine (South Morocco) Edrioasteroids The enormous neural spines ofCalcite 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".
