Honey Calcite

Physical Properties

Hardness: 3 on Mohs scale; Color: Golden yellow to amber; Luster: Vitreous to waxy; Crystal structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral in three directions; Specific gravity: 2.71

Formation & Geological History

Formed through sedimentary processes, typically in marine environments as chemical precipitates or from the shells of marine organisms. It can also form in hydrothermal veins and caves as stalactites.

Uses & Applications

Primary source of lime for cement and mortar; used in the chemical industry, as a soil conditioner in agriculture, and as decorative gemstones and carvings in the metaphysical market.

Geological Facts

Honey Calcite is often associated with the 'Golden Ray' in metaphysical circles. It is famous for its optical properties, specifically double refraction, where light passing through a clear crystal splits into two rays.

Field Identification & Locations

Identify in the field by its distinctive golden color and its reaction to dilute hydrochloric acid (it will effervesce/fizz). It is much softer than quartz and can be scratched by a copper penny. Commonly found in Mexico, Brazil, and the USA.
