Physical properties

Hardness: 3 on Mohs scale; Color: Honey-yellow to amber-orange; Luster: Vitreous to resinous; Crystal structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral.

Formation & geological history

Formed through sedimentary processes, primarily from the chemical precipitation of calcium-rich water in caves or around hot springs, typically in Phanerozoic era environments.

Uses & applications

Primarily used for decorative purposes, metaphysical collecting, and as a source of lime in various industrial applications.

Geological facts

Commonly known as 'Honey Calcite,' it is one of the most common minerals on Earth and can double-refract light, a property known as birefringence.

Field identification & locations

Identified by its relatively soft surface (can be scratched by a copper coin) and its reactive bubbling when exposed to weak acids like vinegar. Common in Mexico and Brazil.
