Tumbled honey calcite (likely aragonite/calcite material)

Calcite, CaCO₃; possibly aragonite, a polymorph of CaCO₃

AI-generated identification · may be incorrect

Pale honey-yellow, translucent, waxy to vitreous luster, massive and visibly veined; calcite hardness Mohs 3, perfect rhombohedral cleavage, specific gravity ~2.71. It effervesces strongly with dilute hydrochloric acid or vinegar, though polished surfaces may react slowly.

Physical properties

Formation & geological history

Forms from carbonate-rich groundwater, hydrothermal veins, caves, or sedimentary limestone; the specimen is likely polished or tumbled. Carbonate deposits may range from recent to Paleozoic or older, but age cannot be determined from appearance.

Uses & applications

Used as an ornamental stone, carving material, cabochons, and metaphysical décor; calcite is also important industrially for cement, lime, aggregate, and glass.

Geological facts

Its honey color commonly comes from iron or other trace impurities. Calcite can be distinguished from quartz by its much lower hardness and acid reaction.

Field identification & locations

Common in Mexico, the United States, Iceland, Brazil, and China; identify by softness, rhombohedral cleavage, and acid fizz. Avoid harsh chemicals and scratching during cleaning.
