Physical properties

Hardness: 7 on Mohs scale; Color: Pink, rose-red; Luster: Vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: Indistinct; Specific Gravity: 2.65.

Formation & geological history

Formed through the cooling and crystallization of magma in pegmatites. The pink color is generally attributed to microscopic inclusions of pink fibrous minerals like dumortierite.

Uses & applications

Primarily used for jewelry and decorative carvings. It is also a popular specimen for crystal collecting and metaphysical use.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms well-defined crystal faces and usually occurs in massive form. It is the unofficial state mineral of South Dakota.

Field identification & locations

Identify by its translucent pink color and high hardness (it will scratch glass). Commonly found in Brazil, South Africa, India, and Madagascar.
