Honey calcite (likely)

Calcite, calcium carbonate (CaCO₃)

AI-generated identification · may be incorrect

Translucent honey-yellow to brown, with vitreous to pearly luster and prominent rhombohedral cleavage; Mohs hardness 3, trigonal crystal system, and specific gravity about 2.71. The specimen appears massive and partly crystalline, with iron-oxide staining or included clay.

Physical properties

Formation & geological history

Calcite commonly precipitates from groundwater, hydrothermal fluids, cavities, and sedimentary environments. Its exact age and locality cannot be determined from the photograph.

Uses & applications

Used for cement, lime, aggregate, and chemical manufacture; attractive honey calcite is collected and sometimes cut for decorative objects, though it is too soft for most jewelry.

Geological facts

Calcite strongly effervesces in dilute hydrochloric acid and shows birefringence through clear fragments. Color commonly results from iron, organic material, or other inclusions rather than the pure mineral.

Field identification & locations

Identify it by rhombohedral cleavage, softness, and acid reaction; a steel knife can scratch it, unlike quartz. Common worldwide, especially in limestone caves, veins, and hydrothermal deposits.
