Raw honey calcite (likely)

Calcite, CaCO₃

AI-generated identification · may be incorrect

Translucent honey-yellow to tan, vitreous to pearly luster, and uneven to rhombohedral cleavage; Mohs hardness 3, trigonal crystal system, specific gravity about 2.7. The photo shows a rough, massive specimen; identification from appearance alone is uncertain.

Physical properties

Translucent honey-yellow to tan, vitreous to pearly luster, and uneven to rhombohedral cleavage; Mohs hardness 3, trigonal crystal system, specific gravity about 2.7. The photo shows a rough, massive specimen; identification from appearance alone is uncertain.

Formation & geological history

Calcite precipitates from mineral-rich groundwater and hydrothermal fluids, and also forms in caves and sedimentary deposits. It occurs from many geological ages; the specimen’s age and locality cannot be determined from the image.

Uses & applications

Used in cement, lime, and other industrial products; attractive translucent pieces are collected or cut for decorative objects and jewelry.

Geological facts

Calcite effervesces in dilute hydrochloric acid and can show double refraction in clear crystals.

Field identification & locations

Look for low hardness, rhombohedral cleavage, and acid reaction; calcite is widespread in limestone, caves, and hydrothermal veins worldwide. A locality label or simple hardness/acid tests would help confirm the identification.
