Physical properties
Hardness of 3 on the Mohs scale, vibrant orange to yellow color, vitreous to resinous luster, rhombohedral crystal system, and perfect rhombohedral cleavage.
Formation & geological history
Forms primarily in sedimentary environments through the precipitation of calcium carbonate from water solutions, as well as in hydrothermal veins.
Uses & applications
Widely used in decorative carvings, polished display specimens, and metaphysical practices due to its vibrant color.
Geological facts
Orange calcite is known for exhibiting strong birefringence, meaning it splits light rays to create a double-image effect.
Field identification & locations
Easily identified by its characteristic 3-direction cleavage and strong effervescence when exposed to dilute hydrochloric acid; found globally with notable deposits in Mexico.
