Physical properties
Hardness: 3 on Mohs scale; Color: Orange to pale honey; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: Perfect rhombohedral; Specific gravity: 2.71
Formation & geological history
Formed in sedimentary environments through chemical precipitation from calcium-rich solutions, or in metamorphic marble. It is found in massive form and in hydrothermal veins.
Uses & applications
Used as a decorative stone, in jewelry (though soft), as an acid neutralizer in the chemical industry, and as a popular specimen for crystal healing collectors.
Geological facts
Orange calcite is often called the 'stone of creativity.' It reacts violently with even weak acids like vinegar, producing carbon dioxide bubbles.
Field identification & locations
Identified in the field by its softness (can be scratched by a copper coin) and its rhombohedral cleavage. It is commonly found in Mexico, Brazil, and the USA.
