Physical properties

Hardness: 3 on Mohs scale. Color: Pale pink to peach. Luster: Vitreous to pearly. Crystal structure: Trigonal/Rhombohedral. Cleavage: Perfect rhombohedral in three directions. Specific Gravity: 2.71.

Formation & geological history

Formed through sedimentary precipitation in marine environments or hydrothermal veins. It can also occur in metamorphic marble. It is found in geological formations spanning from the Precambrian to Holocene.

Uses & applications

Used in the manufacture of cement and lime, as a soil conditioner in agriculture, and as a decorative stone or lapidary material. Metaphysical collectors value it for its aesthetic pink hue.

Geological facts

Calcite is one of the most common minerals on Earth. The pink variety, often called Manganoan Calcite, gets its color from trace amounts of manganese within the crystal lattice.

Field identification & locations

Identify in the field by its rhombohedral cleavage and its strong reaction (fizzing) to cold dilute hydrochloric acid. It is significantly softer than quartz and can be scratched by a copper coin.
