Physical properties
Hardness: 7 on the Mohs scale; Color: Pink to rose red; Luster: Vitreous/Glassy; Crystal structure: Trigonal/Hexagonal system; Cleavage: None (conchoidal fracture); Specific gravity: 2.65.
Formation & geological history
Formed in pegmatites and hydrothermal veins through the crystallization of magma. Common in various geological ages ranging from Precambrian to more recent igneous formations.
Uses & applications
Used extensively in jewelry (beads, cabochons), ornamental carvings, crystal healing practices, and as a collector's specimen.
Geological facts
Legend has it that Rose Quartz was used by ancient Egyptians and Romans in facial masks to clear complexions and reduce wrinkles. Unlike most quartz varieties, it rarely forms distinct large crystals, usually occurring in massive aggregates.
Field identification & locations
Identify in the field by its distinct pink color, lack of cleavage, and ability to scratch glass. Found globally, with major deposits in Brazil, Madagascar, South Africa, and the United States (South Dakota).
