Calcite (CaCO₃)
AI-generated identification · may be incorrectLikely a rough, pale green calcite fragment with a vitreous-to-pearly luster and visible cleavage surfaces. Calcite has Mohs hardness 3, trigonal crystal structure, and perfect rhombohedral cleavage; the image alone cannot confirm the identification.

Physical properties
Likely a rough, pale green calcite fragment with a vitreous-to-pearly luster and visible cleavage surfaces. Calcite has Mohs hardness 3, trigonal crystal structure, and perfect rhombohedral cleavage; the image alone cannot confirm the identification.
Formation & geological history
Forms in sedimentary limestones and caves, hydrothermal veins, and metamorphic marble; calcite occurs in rocks of many geological ages.
Uses & applications
Used in cement and lime production, construction, and as a decorative or collectible mineral; attractive translucent pieces may be used in carvings or jewelry.
Geological facts
Calcite effervesces in dilute hydrochloric acid and can show strong double refraction in clear crystals.
Field identification & locations
The pale color and blocky cleavage are consistent with calcite, but visual identification is uncertain; a vinegar/acid reaction and scratch test can help distinguish it from harder minerals. Calcite is widespread worldwide.
