Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous to greasy; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Usually found in the cores of pegmatites and late-stage hydrothermal veins. It forms at high temperatures and pressures deep within the Earth's crust.

Uses & applications

Primarily used in jewelry (rings, necklaces, carvings), decorative ornaments, and by collectors. Often used in metaphysical practices.

Geological facts

Rose quartz is famous for its distinct pink hue, which is thought to be caused by microscopic inclusions of fibrous dumortierite-like minerals. It is traditionally known as the stone of unconditional love.

Field identification & locations

Identify by its characteristic pink color and lack of clearly defined crystal faces (it usually occurs in massive form). Found commonly in Brazil, Madagascar, South Africa, and the United States (South Dakota).
