Physical properties
Hardness of 3 on the Mohs scale, pale to bright yellow color, vitreous to pearly 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 water solutions rich in calcium and carbonate.
Uses & applications
Used in optical applications, construction materials, neutralizing acids, and as decorative or metaphysical polished stones.
Geological facts
Calcite is the primary constituent of limestone and marble, and it exhibits strong birefringence, meaning it splits light into two separate rays.
Field identification & locations
Easily identified by its characteristic rhombohedral cleavage and strong fizzing reaction when exposed to dilute hydrochloric acid; found worldwide.
