Physical properties
Hardness: 3 (Mohs scale), Color: Amber to pale golden yellow, Luster: Vitreous to resinous, Crystal Structure: Trigonal (rhombohedral), Cleavage: Perfect rhombohedral in three directions, Specific Gravity: 2.71
Formation & geological history
Forms in sedimentary environments through chemical precipitation from calcium-rich solutions or as a secondary mineral in igneous hydrothermal veins. It can be found in limestone caves and hot springs.
Uses & applications
Used primarily for ornamental carvings, decorative stones, beads in jewelry, and as a popular specimen for mineral collectors and metaphysical practitioners.
Geological facts
Honey calcite is known for its distinct rhombohedral cleavage, meaning it naturally breaks into slanted box-like shapes. If you place a drop of cold dilute hydrochloric acid on it, it will effervesce (fizz) vigorously.
Field identification & locations
Identify in the field by its softness (can be scratched by a copper penny but not a fingernail) and its waxy or 'soapy' feel. Common locations include Mexico, Utah (USA), and Brazil.
