Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy); Crystal structure: Hexagonal/Trigonal (usually found in massive form rather than distinct crystals); Cleavage: None (conchoidal fracture); Specific gravity: 2.65.

Formation & geological history

Formed in late-stage cooling of granitic pegmatites or hydrothermal veins. The pink color is generally attributed to microscopic inclusions of a fibrous pink borosilicate mineral similar to dumortierite.

Uses & applications

Commonly used in jewelry (cabochons, beads), decorative carvings, spheres, and as a popular specimen for crystal collecting and metaphysical purposes.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms well-terminated crystals; it is almost always found in large, shapeless lumps called 'masses.' It is known as the 'stone of unconditional love' in folklore.

Field identification & locations

Identify in the field by its characteristic cloudy pink color and high hardness (it will scratch glass). Commonly found in Brazil, Madagascar, South Africa, and the Black Hills of South Dakota, USA.
