Physical properties
Hardness: 3 (Mohs scale), Color: Orange to honey-gold, Luster: Vitreous to waxy, Crystal Structure: Trigonal (rhombohedral cleavage), Specific Gravity: 2.71
Formation & geological history
Forms in sedimentary environments through chemical precipitation from calcium-rich solutions, or in metamorphic marble. It is a common rock-forming mineral found worldwide.
Uses & applications
Used primarily as decorative carvings, tumbled stones for collectors, and in the metaphysical community. Industrial calcite is used in cement, antacids, and soil treatment.
Geological facts
Calcite is famous for its double refraction (birefringence) property, where light passing through a clear specimen splits into two rays. Orange varieties get their color from hematite or iron oxide inclusions.
Field identification & locations
Identify by its distinct rhombohedral cleavage (slanted cube shape) and its characteristic effervescence (bubbling) when in contact with dilute hydrochloric acid.
