Physical properties

Hardness: 7 on the Mohs scale. Color: Pale pink to rose red. Luster: Vitreous (glassy). Crystal Structure: Hexagonal (trigonal), though it usually occurs in massive form. Cleavage: None (conchoidal fracture). Specific Gravity: 2.65.

Formation & geological history

Formed in high-temperature silica-rich pegmatites as magma cools slowly. The distinct pink color is attributed to microscopic inclusions of dumortierite or similar fibrous minerals. They can be found in geological formations ranging from Precambrian to more recent igneous intrusions.

Uses & applications

Used extensively in jewelry for beads, cabochons, and carvings. Also popular in the lapidary arts for ornamental objects, spheres, and as a collector's item in metaphysical communities. Lower grade material is used in home decor and landscaping.

Geological facts

Known as the 'Stone of Love.' While most rose quartz is translucent/massive, rare specimens from Brazil can exhibit asterism (a star-like light effect) due to aligned needle-like inclusions. It is distinct from 'pink quartz,' which forms rare individual crystals.

Field identification & locations

Identify in the field by its distinct pink hue, lack of apparent crystal faces (in 'massive' form), and its ability to scratch glass. Commonly found in Brazil, Madagascar, South Africa, and the Black Hills of South Dakota (USA).
