Physical properties
Hardness: 3 on Mohs scale; Color: Orange to honey-gold; Luster: Vitreous to waxy; Crystal structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral; Specific gravity: 2.71
Formation & geological history
Formed through sedimentary processes or hydrothermal activity. Often found in massive forms within limestone or marble deposits throughout various geological eras including the Phanerozoic eon.
Uses & applications
Commonly used as a decorative stone, in lapidary work for cabochons and carvings, and as a popular specimen for metaphysical collectors.
Geological facts
Calcite is the most common form of calcium carbonate. High-quality orange specimens often exhibit a 'waxy' texture that feels almost like soap or plastic to the touch.
Field identification & locations
Identifiable by its 3-way cleavage and reaction (fizzing) to diluted hydrochloric acid. Commonly found in Mexico, Brazil, and the USA. Collectors look for vibrant saturation and translucency.
