Honey/orange calcite

Calcite (calcium carbonate, CaCO₃)

AI-generated identification · may be incorrect

Typically amber to orange, translucent, with vitreous to pearly luster and prominent rhombohedral cleavage; Mohs hardness 3, specific gravity about 2.71. The irregular piece appears crystalline and may show cleavage faces rather than conchoidal fracture.

Physical properties

Formation & geological history

Calcite commonly forms in hydrothermal veins, carbonate rocks, caves, and sedimentary environments through precipitation from calcium-rich fluids. Its age can range from recent to hundreds of millions of years, depending on its host deposit.

Uses & applications

Used in cement, lime, aggregate, soil treatment, and chemical manufacturing; attractive transparent crystals are collected and occasionally used as lapidary material, though softness limits jewelry use.

Geological facts

Calcite effervesces strongly in dilute hydrochloric acid and displays double refraction in clear pieces. Orange color may result from iron impurities or inclusions.

Field identification & locations

Look for rhombohedral cleavage, low hardness, and acid reaction; it can be scratched by a copper coin or steel knife. Common localities include Mexico, Iceland, the United States, and many carbonate-bearing regions.
