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”.
Calcite is derived from the German Calcit, a term coined in the 19th century from the Latin word for lime, calx (genitive calcis) with the suffix -ite used to name minerals.It is thus etymologically related to chalk.
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.
