Honey calcite (yellow calcite)

Calcite, CaCO₃

AI-generated identification · may be incorrect

Translucent golden-yellow to amber, vitreous to pearly luster, Mohs hardness 3, trigonal crystal structure, and prominent rhombohedral cleavage. The rounded, hand-held specimen appears rough or naturally worn; color alone cannot confirm identification.

Physical properties

Formation & geological history

Calcite forms in sedimentary carbonate rocks, veins, and cavities from mineral-rich water; it occurs from many geological ages. Yellow coloration commonly results from trace impurities or inclusions.

Uses & applications

Used as a decorative and collector mineral, and occasionally carved; calcite is also an important industrial source of lime and cement, though this specimen is primarily ornamental.

Geological facts

Calcite effervesces in dilute hydrochloric acid and is readily scratched by a copper coin or knife. Its double refraction is especially visible in clear, uncolored crystals.

Field identification & locations

Common in limestone and marble deposits worldwide, including Mexico, the United States, and parts of Europe. Check for easy scratching and rhombohedral cleavage; confirm with a hardness or acid test, since yellow quartz and other minerals can look similar.
