Physical properties
Hardness: 3 on Mohs scale; Color: Honey-yellow to pale lemon; Luster: Vitreous to waxy; Crystal Structure: Trigonal/Hexagonal; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71
Formation & geological history
Forms in sedimentary environments through chemical precipitation from calcium-rich solutions, also found in hydrothermal veins and as a primary mineral in igneous carbonatites.
Uses & applications
Used as an acid neutralizer in chemical industries, a component in cement, for decorative carvings, and widely collected as a metaphysical or healing stone.
Geological facts
Calcite displays double refraction; if you place a clear crystal over a line, it will appear as two lines. It is also the main constituent of limestone and marble.
Field identification & locations
Identify by its 'soapy' or waxy feel and its vigorous reaction (effervescence) when touched with a drop of weak acid such as vinegar. Often found in limestone quarries worldwide.
