Physical properties
Mohs hardness of 3, yellow to orange color, vitreous to pearly luster, trigonal crystal system, and perfect rhombohedral cleavage.
Formation & geological history
Forms primarily in sedimentary environments through the precipitation of calcium carbonate-rich waters, often in limestone caves or hydrothermal veins.
Uses & applications
Used widely in optical products, construction materials, agricultural soil conditioning, and as a popular polished gemstone for collectors.
Geological facts
Calcite exhibits strong double refraction, splitting light passing through it into two separate rays. It is the primary mineral component of limestone and marble.
Field identification & locations
Easily identified by its distinct rhombohedral cleavage and strong effervescence when exposed to dilute hydrochloric acid. Found globally.
