Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, where trace elements and microscopic inclusions create its color; some color is associated with phosphate or iron-bearing inclusions. Deposits are generally Precambrian to younger, depending on locality.

Uses & applications

Used for beads, carvings, cabochons, decorative objects, and inexpensive jewelry; massive material is also collected as an ornamental stone.

Geological facts

Unlike many quartz varieties, rose quartz commonly occurs massive rather than as well-formed crystals. Its pink color may fade with prolonged strong sunlight or heating.

Field identification & locations

Identify it by its pink color, quartz-like hardness, glassy polish, lack of obvious cleavage, and ability to scratch ordinary glass. Common sources include Brazil, Madagascar, India, South Africa, and the United States; definitive identification may require hardness or gemological testing.
