Physical properties

Formation & geological history

Forms chiefly in granitic pegmatites and hydrothermal veins when silica-rich fluids crystallize; its pink color commonly results from microscopic inclusions. Quartz is geologically widespread and forms from Precambrian to modern deposits.

Uses & applications

Used as a decorative stone, beads, carvings, and inexpensive cabochons; massive rose quartz is also used for ornamental objects and collector specimens.

Geological facts

Rose quartz commonly occurs massive rather than as well-formed crystals. The pictured piece could also be pink glass or another quartz-rich material, since photographic identification cannot confirm composition.

Field identification & locations

Look for glassy luster, conchoidal edges, lack of cleavage, and resistance to scratching by steel; quartz should scratch ordinary glass. Common sources include Brazil, Madagascar, India, and the United States.
