Honey Calcite

Physical Properties

Hardness: 3 on Mohs scale; Color: Honey-yellow, amber, or pale golden; Luster: Vitreous to waxy; Crystal Structure: Trigonal; Cleavage: Perfect rhombohedral in three directions; Specific Gravity: 2.71

Formation & Geological History

Formed through sedimentary processes, primarily from the chemical precipitation of calcium-rich waters in caves or marine environments. It can also occur in hydrothermal veins.

Uses & Applications

Used primarily for lapidary work including carvings, beads, and metaphysical specimens. Industrial calcite is used in cement, antacids, and soil treatment.

Geological Facts

Honey Calcite is often carved into various shapes like this skull. It is a common mineral that can exhibit double refraction (birefringence) when clear, though this opaque variety is valued for its warm color.

Field Identification & Locations

Identify by its softness (can be scratched by a copper coin) and its energetic reaction (fizzing) to dilute hydrochloric acid. It is commonly found in Mexico, USA, and Brazil.
