Physical properties
Mohs hardness of 3, yellow to orange color, vitreous to earthy luster, trigonal crystal system, perfect rhombohedral cleavage, specific gravity of 2.71.
Formation & geological history
Formed in sedimentary environments through the precipitation of calcium carbonate from water, often found in hydrothermal veins and limestone caves.
Uses & applications
Used in construction materials, optical equipment, agriculture to neutralize soil acidity, and as a popular mineral specimen for collectors.
Geological facts
Calcite exhibits strong double refraction, splitting light passing through it into two separate rays. It is the primary mineral component of limestone and marble.
Field identification & locations
Easily identified by its characteristic rhombohedral cleavage and effervescence when tested with dilute hydrochloric acid. Commonly found worldwide.
