Physical properties
Hardness: 7 on the Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (Trigonal); Cleavage: Indistinct/Conchoidal fracture; Specific Gravity: 2.65
Formation & geological history
Typically forms at high temperatures in late-stage igneous magmatic pegmatites or hydrothermal veins. Its pink hue is caused by microscopic inclusions of fibrous dumortierite or similar minerals.
Uses & applications
Extensively used in jewelry (faceting, cabochons, beads), ornamental carvings, crystal healing, and as a collector specimen. Minor industrial use in electronics, though synthetic quartz is preferred.
Geological facts
Unlike typical quartz, rose quartz rarely forms well-defined crystal faces and is usually found in massive lumps. It was used by ancient Egyptians for facial masks to prevent wrinkles and aging.
Field identification & locations
Identify by its translucent pink color and ability to scratch glass. Found in massive outcroppings in Brazil, Madagascar, South Africa, and the United States (South Dakota). Look for the lack of cleavage and glassy luster.
