Physical properties
Mohs hardness of 3, pale to dark green color, vitreous to pearly luster, trigonal crystal system, perfect rhombohedral cleavage, and specific gravity of 2.71.
Formation & geological history
Formed in sedimentary environments, hydrothermal veins, and metamorphic marble through precipitation from calcium-rich water solutions.
Uses & applications
Used primarily in mineral collections, decorative carvings, holistic crystal healing, and as a neutralizing agent in industrial applications.
Geological facts
Calcite exhibits strong double refraction (birefringence) and reacts vigorously with dilute hydrochloric acid by effervescing.
Field identification & locations
Identify in the field by its softness (easily scratched by a coin), rhombohedral cleavage, and acid fizz test. Commonly found worldwide.
