Physical properties
Mohs hardness of 3, pale to sky blue color, vitreous to pearly luster, trigonal crystal system, and perfect rhombohedral cleavage.
Formation & geological history
Forms primarily in sedimentary environments through the precipitation of calcium carbonate from marine waters or hydrothermal veins.
Uses & applications
Utilized in holistic crystal healing, decorative carvings, and as mineral specimens for educational and collector displays.
Geological facts
Calcite exhibits strong double refraction, meaning objects viewed through clear crystals appear doubled.
Field identification & locations
Easily identified by its soft 3 Mohs hardness, reactive effervescence when exposed to dilute hydrochloric acid, and characteristic blue hue.
