Physical properties

Hardness of 3 on Mohs scale, pale to vibrant green color, vitreous to pearly luster, trigonal crystal system, and perfect rhombohedral cleavage.

Formation & geological history

Formed in sedimentary environments, hydrothermal veins, and metamorphic marble through the precipitation of calcium-rich solutions.

Uses & applications

Used primarily in decorative items, lapidary arts, metaphysical practices, and as a mineral specimen for collectors.

Geological facts

Green calcite often gets its color from included chlorite or other green minerals trapped during crystal growth.

Field identification & locations

Easily identified by its characteristic rhombohedral cleavage and strong effervescence when exposed to dilute hydrochloric acid; found globally with notable deposits in Mexico.
