Physical properties
Mohs hardness of 3, 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-rich solutions, as well as in hydrothermal veins and hot spring deposits.
Uses & applications
Widely used in ornamental carvings, tumbling, decorative objects, and holistic crystal healing practices.
Geological facts
Calcite is the primary constituent of limestone and marble, and it exhibits strong double refraction when viewed through transparent crystals.
Field identification & locations
Easily identified by its characteristic rhombohedral cleavage and strong effervescence when exposed to dilute hydrochloric acid.
