Physical properties

Formation & geological history

Formed through sedimentary processes, typically in marine environments as chemical precipitates or through the accumulation of shell fragments. It can also form in hydrothermal veins or as cave deposits (stalactites/stalagmites).

Uses & applications

Used in the manufacture of cement and mortar, as a soil conditioner in agriculture, a pigment, and extensively in the gemstone and metaphysical collector market.

Geological facts

Calcite is one of the most common minerals on Earth and is the primary constituent of limestone and marble. Honey calcite specifically is prized for its warm, translucent color which is caused by trace impurities of iron.

Field identification & locations

Identify in the field by its 3-way rhombohedral cleavage and its high reactivity to cold dilute hydrochloric acid (it will effervesce/fizz). It is softer than a copper penny.
