Physical properties

Hardness: 3 on Mohs scale. Color: Honey-yellow to amber. Luster: Vitreous to pearly. Crystal system: Trigonal/Hexagonal. Cleavage: Perfect rhombohedral in three directions. Specific gravity: 2.71.

Formation & geological history

Formed through sedimentary processes, often as a chemical precipitate in marine environments or through hydrothermal deposition in veins. It is a major constituent of limestone and marble.

Uses & applications

Used primarily as a decorative stone, in jewelry (though soft), as a metaphysical healing crystal, and in the production of cement and lime for construction.

Geological facts

Honey Calcite is known for its property of double refraction, where a single ray of light entering the crystal is split into two. It is also often fluorescent under UV light.

Field identification & locations

Identify in the field by its rhombohedral cleavage, 3-hardness (can be scratched by a copper coin), and strong effervescence when exposed to cold dilute hydrochloric acid. Commonly found in Mexico, Brazil, and the USA.
