Physical properties

Formation & geological history

Formed through sedimentary processes such as chemical precipitation in marine environments or through hydrothermal activity. Found in massive, crystalline, or stalactitic forms. Most specimens are from the Phanerozoic eon.

Uses & applications

Primarily used as a lapidary material for carvings and decorative items. In industrial forms, calcite is used in building materials, agricultural soil treatments, and the manufacture of glass and paper.

Geological facts

Honey calcite is known for its distinct golden glow when backlit. Calcite is the primary mineral found in limestone and marble. It can demonstrate double refraction if the specimen is sufficiently clear.

Field identification & locations

Identified by its rhombohedral cleavage and its vigorous reaction (effervescence) to cold dilute hydrochloric acid. It is common in limestone quarries and karst landscapes globally. Collectors look for uniform color and transparency.
