Physical properties

Hardness: 7 (Mohs scale), Color: Pale pink to rose red, Luster: Vitreous, Crystal structure: Trigonal (hexagonal), Cleavage: None (conchoidal fracture), Specific Gravity: 2.65

Formation & geological history

Formed in coarse-grained igneous rocks called pegmatites. The pink color is generally attributed to trace amounts of titanium, iron, or manganese, or microscopic inclusions of didumortierite.

Uses & applications

Primarily used for ornamental purposes, carvings, jewelry (cabochons and beads), and as a popular collector's mineral. Occasionally used in the production of glass and abrasives if industrial grade.

Geological facts

Unlike most other varieties of macrocrystalline quartz, rose quartz is rarely found as well-formed individual crystals and usually occurs in massive form. It is often associated with unconditional love in various cultural beliefs.

Field identification & locations

Identify in the field by its distinct pink hue and lack of crystal faces (usually massive). Common locations include Brazil, South Africa, India, and Madagascar. In the US, it is famously found in the Black Hills of South Dakota.
