Physical properties

Mohs hardness 7; pale translucent pink, vitreous-to-waxy luster, typically massive rather than visibly crystalline, with indistinct cleavage and conchoidal fracture. Specific gravity is about 2.65.

Formation & geological history

Forms mainly in granitic pegmatites and hydrothermal quartz veins when trace elements and microscopic inclusions produce its pink color; specimens may be Precambrian to younger. The rounded shape indicates human tumbling and polishing.

Uses & applications

Used for inexpensive cabochons, beads, carvings, polished stones, and mineral collections; it has little industrial value compared with clear quartz.

Geological facts

Rose quartz commonly owes its color to microscopic fibrous inclusions, often associated with dumortierite-like material, rather than simple iron staining. Transparent, well-formed crystals are rare.

Field identification & locations

Identify it by its uniform pink color, translucent edges, hardness sufficient to scratch glass, and lack of obvious cleavage; avoid confusing it with pink calcite, which is softer and effervesces in acid. Common sources include Brazil, Madagascar, India, and South Africa.
