Physical properties
Hardness of 3 on the Mohs scale, reddish-orange to brown color, vitreous to earthy luster, rhombohedral crystal structure, perfect cleavage in three directions, specific gravity around 2.71
Formation & geological history
Formed in hydrothermal veins, sedimentary environments, and metamorphic rocks through the precipitation of calcium carbonate from solution
Uses & applications
Used in mineral collections, decorative carvings, and metaphysical applications
Geological facts
Red calcite often fluoresces pink or red under shortwave ultraviolet light due to trace impurities
Field identification & locations
Identified by its rhombohedral cleavage and effervescence when tested with a weak acid like vinegar; commonly found worldwide, notably in Mexico
