Physical properties

Hardness of 3 on the Mohs scale, orange to yellowish-orange color, vitreous to waxy luster, trigonal crystal system, perfect rhombohedral cleavage, and a specific gravity of approximately 2.71.

Formation & geological history

Forms in sedimentary environments through the precipitation of calcium carbonate from water solutions, as well as in hydrothermal veins and metamorphic marble deposits.

Uses & applications

Widely used in decorative items, lapidary arts, mineral collections, and metaphysical practices for energy amplification.

Geological facts

Orange calcite is known for its bright, warm energy and often exhibits strong white to orange fluorescence under ultraviolet (UV) light due to trace impurities.

Field identification & locations

Easily identified by its characteristic orange color, lower hardness (easily scratched by a copper penny), and strong effervescence (bubbling) when tested with a weak acid like vinegar.
