Physical properties

Hardness of 7 on the Mohs scale, pink to rose-red color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture with no true cleavage.

Formation & geological history

Forms primarily in pegmatites and hydrothermal veins through the cooling of magma rich in silica, often with trace amounts of titanium, iron, or manganese.

Uses & applications

Widely used in ornamental carvings, gemstone jewelry, holistic crystal healing, and decorative tumbled stones.

Geological facts

The distinct pink color is attributed to microscopic fibers of dumortierite or microscopic inclusions of pink spinel within the quartz matrix.

Field identification & locations

Easily identified by its distinct pink hue, lack of cleavage, and quartz hardness that scratches glass; commonly sourced from Brazil, Madagascar, and the USA.
