Yellow calcite (honey calcite)

Calcite, CaCO₃

AI-generated identification · may be incorrect

Translucent pale-yellow to honey-colored piece with vitreous to dull luster and irregular fracture; calcite is Mohs 3, trigonal, with perfect rhombohedral cleavage and specific gravity about 2.7. The rough, partly cloudy appearance is consistent with calcite, though a photo cannot confirm the identification.

Physical properties

Formation & geological history

Usually forms when calcium-rich fluids precipitate calcite in veins, cavities, or sedimentary settings; calcite occurs in rocks of many geological ages.

Uses & applications

Used in construction, cement and lime production, and as a decorative or collecting mineral; clear, attractive pieces may be polished or fashioned into ornaments.

Geological facts

Calcite effervesces in dilute hydrochloric acid, and transparent varieties can show strong double refraction.

Field identification & locations

Look for rhombohedral cleavage and test a hidden spot with dilute acid; calcite is widespread in limestone, marble, and hydrothermal veins worldwide. The specimen’s color may come from iron or other trace impurities.
