Physical properties
Hardness: 7 on Mohs scale; Color: pale pink to rose red; Luster: Vitreous; Crystal Structure: Hexagonal (trigonal); Cleavage: None; Specific Gravity: 2.65.
Formation & geological history
Formed at high temperatures in magma (igneous) or in hydrothermal veins. Large crystals are rare; it most commonly occurs in massive form within pegmatites.
Uses & applications
Predominantly used for jewelry (cabochons, beads, faceted), ornamental carvings, and as a popular healing stone in metaphysical communities.
Geological facts
Unlike most other varieties of quartz, rose quartz does not form macroscopic crystals but occurs in large masses. The color is thought to be caused by microscopic inclusions of a pink variety of the mineral dumortierite.
Field identification & locations
Identified by its signature pink hue and conchoidal fracture. For collectors, look for translucency and depth of color. Common in Brazil, Madagascar, South Africa, and the United States (South Dakota).
