Physical properties

Translucent amber-orange with a vitreous to pearly luster and prominent cleavage faces. Mohs hardness 3; trigonal crystal system; specific gravity about 2.7.

Formation & geological history

Forms when calcium-carbonate-rich fluids precipitate in veins, cavities, or sedimentary settings; calcite occurs in rocks of many ages. The photo alone does not establish this specimen’s exact origin.

Uses & applications

Commonly collected and used for carvings and decorative objects; calcite is also an important industrial source of lime and a component of cement.

Geological facts

Calcite effervesces in dilute acid and shows double refraction in clear pieces. Orange coloration commonly results from trace impurities.

Field identification & locations

Look for softness, rhombohedral cleavage, and vigorous fizzing with dilute acid; distinguish it from harder amber-colored minerals by hardness and acid reaction. Found worldwide in limestone and hydrothermal deposits.
