Physical properties
Hardness of 3 on the Mohs scale, pale yellow to golden color, vitreous to earthy luster, rhombohedral crystal structure, perfect rhombohedral cleavage, specific gravity of 2.71
Formation & geological history
Forms in sedimentary environments through the precipitation of calcium carbonate from solution, as well as in hydrothermal veins and metamorphic marbles
Uses & applications
Used in decorative items, lapidary arts, mineral collections, and metaphysical practices; industrial calcite is used in construction and manufacturing
Geological facts
Calcite exhibits strong double refraction (birefringence), where objects viewed through clear crystals appear doubled
Field identification & locations
Easily identified by its characteristic rhombohedral cleavage and effervescence (bubbling) when tested with weak hydrochloric acid; found worldwide
