Physical properties
Translucent honey-yellow pieces with vitreous to pearly luster and prominent rhombohedral cleavage; Mohs hardness 3, trigonal crystal structure, and specific gravity about 2.71. The left piece appears polished or naturally rounded, while the others show cleavage surfaces and possible iron-oxide staining.
Formation & geological history
Likely formed as a low-temperature hydrothermal or cavity-filling mineral in limestone or volcanic host rock; calcite occurs from Precambrian to recent geological settings. The golden color commonly reflects iron or other trace-element impurities.
Uses & applications
Used for ornamental specimens, carved objects, optical demonstrations, cement, lime, and aggregate; transparent varieties are collectible but relatively soft and easily scratched.
Geological facts
Calcite effervesces strongly with dilute hydrochloric acid or household vinegar, especially on a freshly exposed surface. It exhibits strong birefringence, producing doubled images through clear pieces.
Field identification & locations
Common worldwide, including Mexico, the United States, Iceland, China, and Peru. Identify it by rhombohedral cleavage, softness, and acid reaction; avoid prolonged soaking or abrasion.
