Physical properties
Mohs hardness of 3, white to yellow color, vitreous to earthy luster, rhombohedral cleavage, specific gravity of 2.71.
Formation & geological history
Formed in sedimentary environments through precipitation of calcium carbonate from marine waters or hydrothermal vein systems.
Uses & applications
Used in optical applications, manufacturing of lime and cement, soil conditioning, and as a popular collector mineral or decorative gemstone.
Geological facts
Calcite exhibits strong double refraction (birefringence), meaning light passing through it is split into two separate rays.
Field identification & locations
Identified easily by its soft hardness, reactive effervescence when exposed to dilute hydrochloric acid, and perfect rhombohedral cleavage.
