Physical properties
Hardness: 7 (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
Forms primarily in late-stage crystallization of granitic pegmatites and hydrothermal veins, typically at high temperatures. The pink hue is attributed to microscopic inclusions of fibrous dumortierite or similar minerals.
Uses & applications
Used extensively in jewelry, ornamental carvings, lapidary arts, and metaphysical practices. Historically used for seals and beads.
Geological facts
Unlike other varieties of quartz, rose quartz rarely forms large, well-defined crystals; it is usually found in massive, chunky habits. Large deposits are found in Brazil, South Africa, and Madagascar.
Field identification & locations
Identifiable by its distinct pink hue and lack of crystal faces (massive form). Can be found in pegmatite outcrops. Often shows 'asterism' (a star effect) when cut as a cabochon.
