Physical properties

Hardness of 3 on the Mohs scale, orange to yellow color, vitreous to pearly luster, trigonal crystal system, and perfect rhombohedral cleavage.

Formation & geological history

Forms primarily in sedimentary environments through the precipitation of calcium carbonate from water, as well as in hydrothermal veins and metamorphic marbles.

Uses & applications

Used widely in decorative carvings, metaphysical healing, sculpture, and as a calcium source in various industrial chemical applications.

Geological facts

Orange calcite gets its vibrant color from included traces of iron and exhibits strong negative reaction (effervescence) when exposed to weak hydrochloric acid.

Field identification & locations

Easily identified by its characteristic rhombohedral cleavage and low hardness that allows it to be easily scratched by a copper coin; commonly sourced from Mexico.
