Physical properties

Mohs hardness of 3, pale to dark green color, vitreous to pearly luster, trigonal crystal system, perfect rhombohedral cleavage, specific gravity of 2.71.

Formation & geological history

Formed through the precipitation of calcium carbonate in low-temperature hydrothermal veins, sedimentary environments, or metamorphic limestone.

Uses & applications

Widely used in decorative carvings, metaphysical collections, and as a raw material for various industrial applications.

Geological facts

Green calcite often gets its color from included chlorite or other green minerals trapped during crystal growth. It exhibits strong effervescence when exposed to dilute hydrochloric acid.

Field identification & locations

Easily identified by its characteristic rhombohedral cleavage, softness (scratched by a copper penny), and acid reaction. Commonly found in Mexico, Peru, and the USA.
