Physical properties
Hardness: 7 (Mohs scale), Color: Pale pink to rose red, Luster: Vitreous (glassy), Crystal structure: Hexagonal (trigonal), Cleavage: None (conchoidal fracture), Specific Gravity: 2.65
Formation & geological history
Formed in hydrothermal veins and pegmatites through the slow cooling of silica-rich magma or hot solutions. Most major deposits occur in Precambrian or Paleozoic rock formations.
Uses & applications
Widely used in jewelry (cabochons and beads), ornamental carvings, crystal healing practices, and aggregate in decorative landscaping.
Geological facts
Unlike other varieties of quartz that form large crystals, rose quartz usually occurs in massive form. The pink color is believed to be caused by microscopic inclusions of dumortierite filaments. It is known as the 'Stone of Love' in many cultures.
Field identification & locations
Identify by its characteristic pink hue, high hardness (can scratch glass), and lack of cleavage. Common sources include Brazil, Madagascar, South Africa, and the Black Hills of South Dakota, USA.
