Physical properties

Formation & geological history

Forms mainly in limestone, marble, hydrothermal veins, caves, and sedimentary deposits through precipitation of calcium carbonate. Calcite occurs from Precambrian to Recent geological environments; this specimen’s exact age cannot be determined visually.

Uses & applications

Used in cement, lime, aggregate, soil treatment, and optical instruments; attractive translucent pieces are sold as inexpensive decorative or metaphysical specimens.

Geological facts

Calcite effervesces vigorously in cold dilute hydrochloric acid and shows strong birefringence, producing doubled images through clear pieces. Honey coloration commonly results from iron or other trace impurities.

Field identification & locations

Common worldwide, including Mexico, the United States, Iceland, Brazil, and China. Identify it by its softness, rhombohedral cleavage, and acid reaction; it can be scratched by a copper coin or steel knife.
