Physical properties
Hardness of 3 on the Mohs scale, color ranges from pale yellow to deep golden, vitreous to earthy luster, trigonal crystal system, perfect rhombohedral cleavage, specific gravity of 2.71.
Formation & geological history
Forms in sedimentary, metamorphic, and igneous environments through the precipitation of calcium carbonate from aqueous solutions, often in caves, hot springs, and marine settings.
Uses & applications
Used in optical devices, construction materials, cement manufacturing, soil conditioning, and as a popular mineral specimen for collectors and crystal healing.
Geological facts
Calcite is the primary constituent of limestone and marble. It exhibits strong double refraction (birefringence), meaning light passing through it is split into two rays.
Field identification & locations
Easily identified by its characteristic rhombohedral cleavage and effervescence (fizzing) when exposed to weak hydrochloric acid. Found worldwide, with major deposits in Mexico, the USA, and Madagascar.
