Honey calcite cluster

Calcite (calcium carbonate, CaCO₃)

AI-generated identification · may be incorrect

Typically honey-yellow to amber, translucent, with vitreous to pearly luster and prominent rhombohedral cleavage; Mohs hardness 3, trigonal crystal structure, and specific gravity about 2.71. The specimen appears to be a cluster of cleavage-rich calcite crystals, though the image alone cannot confirm exact identificati…

Physical properties

Formation & geological history

Calcite commonly forms in hydrothermal veins, cavities, sedimentary deposits, and limestone environments when calcium-rich fluids precipitate carbonate minerals. Its age may range from modern cave growth to ancient Paleozoic or younger deposits, depending on locality.

Uses & applications

Used extensively in cement, lime, aggregate, agriculture, and chemical industries; attractive honey-colored clusters are mainly sold as décor or collector specimens rather than jewelry because calcite is soft and easily cleaved.

Geological facts

Calcite effervesces vigorously in dilute hydrochloric acid and shows strong double refraction in clear pieces. Honey coloration commonly results from iron or other trace impurities.

Field identification & locations

Look for rhombohedral cleavage, low hardness, and acid reaction; it can scratch with a steel knife but not glass. Common sources include Mexico, Brazil, China, Morocco, and the United States.
