Physical properties

Formation & geological history

Forms chiefly in granitic pegmatites and hydrothermal veins, crystallizing from silica-rich fluids during Precambrian to younger geological events. The pink color commonly results from microscopic dumortierite-like inclusions or irradiation-related color centers.

Uses & applications

Used for beads, cabochons, carvings, decorative objects, and inexpensive tumbled stones; it is also popular in metaphysical collections. It has little industrial value compared with clear quartz.

Geological facts

Rose quartz commonly occurs as massive material rather than well-formed crystals. Its color can fade with prolonged strong sunlight or heating.

Field identification & locations

Identify it by its uniform soft pink color, translucent edges, glassy luster, hardness sufficient to scratch glass, and lack of cleavage; beware pink glass or dyed quartz. Common sources include Brazil, Madagascar, South Africa, India, and the United States.
