Organic 07810 - Top Beautiful 4.59 Inch Calcite Crystals From South Morocco + Gift Included [goAEMfyN]
Calcite 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".
Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C and vaterite is even less stable.
