Physical properties

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

Formation & geological history

Formed through the cooling of silica-rich magma in pegmatites or hydrothermal veins. The pink color is generally attributed to microscopic inclusions of fibrous dumortierite or trace amounts of titanium and manganese.

Uses & applications

Used extensively in jewelry (cabochons, beads), decorative carvings, lapidary arts, and ornamental architecture. It is also highly popular in the metaphysical community as a 'stone of love.'

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms large, distinct crystals; it is almost always found in large, shapeless masses. It can exhibit asterism (a star-like light effect) when cut into spheres or cabochons if it contains fine rutile needles.

Field identification & locations

Identify in the field by its distinct translucent pink color and vitreous luster; it will scratch glass easily but cannot be scratched by a steel knife. Common locations include Brazil, Madagascar, South Africa, and the Black Hills of South Dakota.
