Physical properties
Mohs hardness of 3, orange to peach color, vitreous to pearly luster, trigonal crystal system, perfect rhombohedral cleavage, specific gravity of 2.71.
Formation & geological history
Formed through the precipitation of calcium carbonate in low-temperature hydrothermal veins, sedimentary environments, and cave deposits.
Uses & applications
Used in optical applications, cement manufacturing, soil conditioning, and as decorative or crystal healing specimens.
Geological facts
Orange calcite exhibits strong white to orange fluorescence under ultraviolet light and effervesces readily in dilute hydrochloric acid.
Field identification & locations
Easily identified by its soft nature, distinct rhombohedral cleavage, and acid reactivity. Found worldwide, particularly in Mexico.
