Physical properties

Hardness: 3 on Mohs scale; Color: Yellow-orange to vivid orange; Luster: Vitreous to waxy; Crystal System: Trigonal; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71

Formation & geological history

Formed through sedimentary processes or as a secondary mineral in igneous rocks via precipitation from calcium-rich hydrothermal fluids. This specific shape is artificially cut and polished.

Uses & applications

Commonly used for ornamental purposes, metaphysical healing practices, decorative home decor, and as a calcium source in chemical industries.

Geological facts

Orange calcite gets its color from tiny inclusions of hematite or iron oxide. It is highly reactive to acids and will effervesce (bubble) if a drop of vinegar or dilute HCl is applied.

Field identification & locations

Identify by its relative softness (can be scratched by a copper coin or steel knife) and its reaction to acid. Often found in Mexico, Brazil, and the USA.
