Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous; Crystal Structure: Hexagonal (trigonal); Cleavage: Indistinct; Specific Gravity: 2.65

Formation & geological history

Formed through the crystallization of magma (igneous) or from hydrothermal veins, typically found in pegmatites. The color is usually attributed to microscopic inclusions of pink borosilicate fibers.

Uses & applications

Primarily used in jewelry, ornamental carvings, decorative home items, and as a popular specimen for gemstone collectors.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms macro-scale crystals and is generally found in massive form. Some specimens show asterism (a star-like effect) when cut into cabochons.

Field identification & locations

Identify by its characteristic pink hue and quartz-like fracture. It is commonly found in Brazil, South Africa, India, and Madagascar.
