Physical properties

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

Formation & geological history

Formed in high-temperature silica-rich magmatic environments, primarily in pegmatites. The pink color is attributed to microscopic inclusions of fibrous dumortierite or similar borosilicate minerals.

Uses & applications

Commonly used in jewelry, ornamental carvings, lapidary arts, and as a popular specimen for gemstone collectors and crystal healing enthusiasts.

Geological facts

Rose quartz rarely forms visible large crystals; it is almost always found in massive form. The first rose quartz beads were found in the area once known as Mesopotamia, dating back to 7000 BC.

Field identification & locations

Identify in the field by its distinct pink color, lack of cleavage (conchoidal fracture), and ability to scratch glass. Widely found in Brazil, Madagascar, South Africa, and the United States (South Dakota).
