Physical properties
Hardness: 3 on Mohs scale. Color: Pale yellow to golden-amber. Luster: Vitreous to resinous. Crystal Structure: Trigonal/Rhombohedral. Cleavage: Perfect rhombohedral in three directions. Specific Gravity: 2.71.
Formation & geological history
Forms in sedimentary environments through chemical precipitation from calcium-rich waters, or in metamorphic marble. It is found in deposits ranging from ancient Paleozoic to more recent Cenozoic formations.
Uses & applications
Used primarily for decorative purposes, metaphysical collecting, as a source of lime in cement, and occasionally in the chemical industry. Softness makes it unsuitable for most jewelry except pendants.
Geological facts
Crystals of calcite are often rhombohedral in shape, meaning they look like a pushed-over box. It is one of the most common minerals on Earth and the primary constituent of limestone and marble.
Field identification & locations
Identify by its 'waxy' appearance and rhombohedral cleavage. In the field, it can be definitively identified by its strong effervescence (fizzing) when exposed to cold dilute hydrochloric acid. Commonly found in Mexico, USA, and Brazil.
