Physical properties

Hardness of 7 on the Mohs scale; pale pink to rose color; vitreous to greasy luster; hexagonal crystal system; conchoidal fracture with no true cleavage; specific gravity of 2.65.

Formation & geological history

Forms primarily in pegmatites, hydrothermal veins, and metamorphic environments through the cooling of silica-rich solutions or regional metamorphism over millions of years.

Uses & applications

Used in gemstone and lapidary arts for decorative carvings, tumbled stones, jewelry, and occasional industrial applications.

Geological facts

Pink coloration is typically attributed to microscopic inclusions of pink dumortierite fibers or titanium, iron, and manganese impurities within the quartz matrix.

Field identification & locations

Can be identified in the field by its distinctive pink hue, lack of cleavage, glass-like luster, and a hardness capable of scratching glass. Found globally, especially in Brazil, Madagascar, and the USA.
