Physical properties
Hardness: 3 on Mohs scale; Color: Yellow, honey yellow, amber; Luster: Vitreous to pearly; Crystal Structure: Trigonal; Cleavage: Perfect rhombohedral cleavage in three directions; Specific Gravity: 2.71
Formation & geological history
Forms in sedimentary, metamorphic, and igneous environments, primarily through the precipitation of calcium carbonate from hydrothermal solutions or marine waters.
Uses & applications
Used in ornamental carvings, metaphysical healing, mineral collecting, and as a source of calcium in various industrial applications.
Geological facts
Calcite exhibits strong double refraction (birefringence), meaning objects viewed through transparent specimens appear doubled.
Field identification & locations
Easily identified by its distinct rhombohedral cleavage and its characteristic fizz when tested with a weak acid like hydrochloric acid. Common worldwide, with major deposits in Mexico, the USA, and Madagascar.
