Physical properties

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

Formation & geological history

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

Uses & applications

Widely used for decorative carvings, ornamental sculptures, holistic healing, and mineral collections.

Geological facts

Green calcite often gets its soft color from included chlorite or iron compounds trapped during crystal growth.

Field identification & locations

Easily identified by its low hardness (scratched by a copper penny) and strong effervescence when exposed to dilute hydrochloric acid.
