Physical properties
Mohs hardness: 3; Color: shades of orange to translucent peach; Luster: vitreous to waxy/greasy; Crystal System: Trigonal; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71
Formation & geological history
Formed through sedimentary processes, primarily from the chemical precipitation of calcium carbonate in marine or hydrothermal environments. Its orange color comes from tiny hematite or iron oxide inclusions.
Uses & applications
Commonly used for ornamental carvings, decorative stones, metaphysical and healing crystal practices, and as a source of lime in chemical industries.
Geological facts
Calcite is one of the most common minerals on Earth and the primary constituent of limestone and marble. Orange calcite is particularly known for its characteristic 'waxy' texture when handled.
Field identification & locations
Can be identified in the field by its 3-way rhombohedral cleavage and its vigorous effervescence when exposed to a drop of dilute cold hydrochloric acid. Common in Mexico and Brazil.
