Physical properties
Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy) to greasy; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Formed in late-stage crystallization of granitic pegmatites or in hydrothermal veins. Often found in massive forms rather than distinct crystals. Geologically linked to the cooling of magma over millions of years.
Uses & applications
Extensively used in lapidary work for jewelry (cabochons, beads), decorative carvings, spheres, and as a popular specimen for collectors and metaphysical enthusiasts.
Geological facts
The pink color is thought to be caused by microscopic inclusions of fibrous dumortierite. Unlike other varieties of quartz, rose quartz rarely forms well-terminated crystals; it is usually found in large, shapeless masses.
Field identification & locations
Identify by its translucent pink color and inability to be scratched by a steel knife. Common locations include Brazil, Madagascar, South Africa, and the Black Hills of South Dakota, USA. Look for milky translucency and a lack of clear planes.
