Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, with pink color from trace elements and microscopic inclusions. Deposits range from Precambrian to younger ages; exact age cannot be determined from the image.

Uses & applications

Used for ornamental objects, carvings, beads, cabochons, and inexpensive jewelry; massive rose quartz is also a popular teaching and collecting specimen.

Geological facts

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

Field identification & locations

Identify it by pink color, glassy/waxy appearance, rounded conchoidal surfaces, and hardness sufficient to scratch ordinary glass; it should not fizz in dilute acid. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
