Physical properties
Hardness: 3 on Mohs scale; Color: Pale to vibrant orange/peach; Luster: Vitreous to waxy; Crystal Structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71
Formation & geological history
Formed through sedimentary processes, often Precipitating in marine environments or through hydrothermal activity. Orange coloration is caused by iron oxide inclusions or other impurities. Commonly found in massive form rather than distinct crystals.
Uses & applications
Primarily used for ornamental purposes, decorative carvings, metaphysical 'healing' stones, and as a calcium source in chemical industries.
Geological facts
Orange calcite is often called the 'stone of creativity.' It reacts vigorously (effervesces) with dilute hydrochloric acid, which is a primary diagnostic test for carbonate minerals.
Field identification & locations
Identify in the field by its characteristic softness (can be scratched by a copper penny) and its waxy 'soapy' feel when polished. Commonly found in Mexico, USA, and Brazil.
