Physical properties
Hardness: 7 on Mohs scale; Color: pale pink to rose red; Luster: Vitreous to greasy; Crystal structure: Hexagonal (Trigonal); Cleavage: Indistinct; Specific Gravity: 2.65
Formation & geological history
Formed at high temperatures in late-stage igneous pegmatites. The pink color is believed to be caused by microscopic inclusions of a pink fibrous mineral related to dumortierite.
Uses & applications
Used extensively in jewelry (beads, cabochons), ornamental carvings, figurines, and as a popular specimen for metaphysical and mineral collectors.
Geological facts
Unlike اکثر other varieties of macro-crystalline quartz, rose quartz rarely forms well-defined crystal faces and usually occurs in massive form. The first known specimens were found in Rumford, Maine, but most supply today comes from Brazil.
Field identification & locations
Identify by its distinctive pink hue, conchoidal fracture (curved breakages), and inability to be scratched by a steel pocket knife. Found commonly in Brazil, South Africa, Madagascar, and the USA (South Dakota).
