Raw honey calcite
Calcite (calcium carbonate, CaCO₃)
AI-generated identification · may be incorrectTypically 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
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.
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.
