Physical properties

Formation & geological history

Forms mainly in hydrothermal veins and pegmatites as granite cools, generally during Precambrian to younger geological events. The specimen is likely mechanically tumbled and polished.

Uses & applications

Used for ornamental carvings, cabochons, beads, décor, and metaphysical collecting; it has little industrial value as a small specimen.

Geological facts

Rose quartz commonly owes its pink color to microscopic inclusions or trace impurities; unlike some quartz varieties, it usually does not form visible crystal points.

Field identification & locations

Identify by its pink color, glassy/waxy surface, lack of cleavage, and resistance to scratching by steel; glass should not scratch it, but quartz can scratch glass. Common sources include Brazil, Madagascar, India, and South Africa.
