Honey calcite (orange calcite)

Calcite, calcium carbonate (CaCO₃)

AI-generated identification · may be incorrect

Translucent honey-orange cleavage fragment with vitreous to pearly luster; Mohs hardness 3, rhombohedral crystal structure, perfect rhombohedral cleavage, and specific gravity about 2.71. The reddish-brown areas are likely iron-oxide staining or inclusions.

Physical properties

Formation & geological history

Forms in sedimentary limestone, hydrothermal veins, and cavity deposits when calcium-rich fluids precipitate calcite. Calcite occurs from Precambrian to modern geological settings; the specimen’s exact age and locality cannot be determined from the image.

Uses & applications

Used in cement, lime, aggregate, soil treatment, and chemical industries; transparent orange material is commonly sold as a lapidary or metaphysical specimen. It is generally too soft for durable jewelry.

Geological facts

Calcite effervesces vigorously in dilute hydrochloric acid and commonly shows strong birefringence through clear fragments. Its coloration commonly results from iron, manganese, or organic impurities.

Field identification & locations

Identify by its softness, rhombohedral cleavage, and acid reaction; it can be scratched with a copper coin or steel knife. Common localities include Mexico, Brazil, the United States, and China.
