Physical properties
Hardness of 3 on the Mohs scale, orange to yellow color, vitreous to pearly luster, trigonal crystal system, and perfect rhombohedral cleavage.
Formation & geological history
Forms in sedimentary environments, hydrothermal veins, and hot spring deposits through the precipitation of calcium carbonate-rich solutions.
Uses & applications
Used widely in decorative carvings, holistic crystal healing, and as a raw material in manufacturing lime and cement.
Geological facts
Orange calcite exhibits strong rhombohedral cleavage and will effervesce vigorously when exposed to dilute hydrochloric acid.
Field identification & locations
Identified easily by its characteristic orange hue, relative softness, and vigorous fizzing reaction with acid; found globally with notable deposits in Mexico.
