Physical properties
Hardness of 7 on the Mohs scale, pink to rose-red color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65
Formation & geological history
Formed mainly in pegmatites and hydrothermal veins, often associated with granitic magmas, or as a constituent of metamorphic and sedimentary rocks through regional metamorphism and weathering
Uses & applications
Used in ornamental carvings, gemstone jewelry, decorative items, and metaphysical practices
Geological facts
The pink coloration is generally attributed to microscopic traces of titanium, iron, or manganese, or possibly microscopic fibrous inclusions of dumortierite
Field identification & locations
Easily identified by its distinctive pink hue, high hardness which scratches glass easily, and lack of cleavage; found worldwide with notable deposits in Brazil, Madagascar, and South Dakota
