Physical properties

Hardness of 3 on the Mohs scale, orange to reddish-orange color with white banding or inclusions, vitreous to resinous luster, trigonal crystal system, perfect rhombohedral cleavage, specific gravity of approximately 2.71.

Formation & geological history

Formed in sedimentary, metamorphic, and igneous environments, commonly precipitated from hydrothermal solutions or evaporating marine waters over millions of years.

Uses & applications

Used in mineral collecting, ornamental carvings, holistic wellness, and as a source of calcium carbonate in various industrial applications.

Geological facts

Orange calcite is known for its high energy and ability to fluoresce under ultraviolet light due to trace impurities.

Field identification & locations

Easily identified by its distinct orange color, rhombohedral cleavage, and characteristic fizz when tested with dilute hydrochloric acid. Commonly found worldwide, especially in Mexico.
