Rose Quartz

Physical Properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (usually found in massive form); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & Geological History

Usually forms in magmatic pegmatites through the cooling of silica-rich hydrothermal fluids. The pink color is generally attributed to microscopic inclusions of pink borosilicate fibers (similar to dumortierite).

Uses & Applications

Used primarily in jewelry (cabochons, beads), luxury interior decoration, ornamental carvings, and historical use in 'healing crystals' or lapidary arts.

Geological Facts

Unlike other varieties of quartz, rose quartz rarely forms well-defined crystal faces; it is almost always found in large, 'massive' chunks. It is the state mineral of South Dakota, USA.

Field Identification & Locations

Identify in the field by its distinctive pink hue, lack of cleavage, and ability to scratch glass. Commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota and New England).
