Physical properties
Hardness 3 on Mohs scale, yellowish-orange color, vitreous to waxy luster, trigonal crystal system, perfect rhombohedral cleavage, specific gravity around 2.71.
Formation & geological history
Formed through chemical precipitation in sedimentary environments, hot springs, or hydrothermal veins where calcium carbonate solutions crystallize.
Uses & applications
Popular as a decorative polished stone, lapidary material, metaphysical healing crystal, and mineral specimen for collectors.
Geological facts
Orange calcite gets its vibrant shade from trace amounts of iron inclusion during its crystallization process. It reacts strongly (effervesces) when exposed to weak acids such as vinegar.
Field identification & locations
Commonly found in places like Mexico, Brazil, Canada, and Madagascar. Identified by its softness (can be scratched by a copper coin or steel nail), waxy texture when tumbled/polished, and orange coloration.
