Physical properties

Formation & geological history

Forms mainly in silica-rich pegmatites and hydrothermal veins, with pink color usually caused by microscopic inclusions of dumortierite-like minerals or other trace elements. Quartz is common from Precambrian to recent geological settings.

Uses & applications

Used for carvings, ornamental objects, tumbled stones, cabochons, and inexpensive jewelry; also popular as a collection and metaphysical specimen.

Geological facts

Rose quartz commonly occurs massive rather than as sharply formed crystals; transparent, well-crystallized pink quartz is comparatively rare. Color can fade with prolonged heat or intense ultraviolet exposure.

Field identification & locations

Identify by its pink hue, glassy luster, hardness, and ability to scratch ordinary glass; it should not fizz in dilute acid. Common localities include Brazil, Madagascar, South Africa, India, and the United States.
