Physical properties
Hardness of 3 on the Mohs scale, orange to yellow color, vitreous to resinous 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 extensively in ornamental carvings, decorative objects, metaphysical practices, and as a source of calcium carbonate in various industries.
Geological facts
Calcite exhibits strong double refraction (birefringence), meaning light passing through a clear specimen splits into two separate rays.
Field identification & locations
Easily identified by its distinct rhombohedral cleavage and characteristic fizz when tested with dilute hydrochloric acid. Commonly found worldwide, especially in Mexico.
