Physical properties

Formation & geological history

Formed through sedimentary processes, often by precipitation from calcium-rich solutions in caves or hot springs, or as marine deposits. This honey-colored variety often originates from Mexico or Utah.

Uses & applications

Primarily used for decorative purposes, lapidary work (cabochons), and mineral collecting. In broader industry, calcite is used in cement, agriculture, and as a dietary supplement.

Geological facts

Calcite is one of the most common minerals on Earth and the primary constituent of limestone and marble. Honey calcite's color is typically derived from minor trace element inclusions like iron.

Field identification & locations

Identify in the field by its rhombohedral cleavage (it breaks into tilted cubes/diamonds) and its strong reaction (effervescence) to cold dilute hydrochloric acid. It is much softer than quartz (which it can resemble), as it can be scratched by a copper coin.
