Physical properties
Translucent pale amber to honey-colored piece with vitreous to pearly luster and visible cleavage surfaces. Mohs hardness 3; trigonal crystal system; perfect rhombohedral cleavage; specific gravity about 2.7.
Formation & geological history
Likely formed through precipitation from calcium-rich water or in a carbonate vein/cavity. Calcite occurs in rocks of many ages, so age and exact origin cannot be determined from the image alone.
Uses & applications
Commonly collected as a specimen; calcite is also used in cement, lime, soil treatment, and optical applications.
Geological facts
Calcite strongly effervesces in dilute hydrochloric acid and may show double refraction in clear crystals.
Field identification & locations
Look for its relatively soft, easily scratched surface and rhombohedral cleavage; common sources include limestone caves and hydrothermal veins worldwide. The specimen’s exact locality is unknown.
