Raw honey calcite

Calcite (calcium carbonate, CaCO₃)

AI-generated identification · may be incorrect

Typically pale honey-yellow to cream, translucent, with a vitreous to pearly luster and prominent rhombohedral cleavage; Mohs hardness 3, specific gravity about 2.71. The irregular blocky shape and cleavage surfaces are consistent with calcite, though aragonite or pale gypsum are possible without testing.

Physical properties

Formation & geological history

Forms in limestone, hydrothermal veins, caves, and evaporite settings through precipitation from carbonate-rich fluids; specimens may range from recent to Paleozoic or older depending on host rock.

Uses & applications

Used industrially for cement, lime, aggregate, soil treatment, and chemical production; attractive transparent crystals are collected, but this rough specimen has modest market value.

Geological facts

Calcite effervesces vigorously with dilute hydrochloric acid or strong vinegar, unlike most look-alikes. It shows strong birefringence, producing doubled images when viewed through a clear fragment.

Field identification & locations

Common worldwide, including Mexico, the United States, Iceland, Brazil, and Morocco; identify with a hardness test, cleavage, and acid reaction. Avoid scratching collectible surfaces.
