Physical properties
Hardness: 7 on Mohs scale. Color: Pale pink to milky light pink. Luster: Vitreous to greasy. Crystal structure: Hexagonal (trigonal). Fracture: Conchoidal. Translucent to semi-translucent.
Formation & geological history
Formed in pegmatites and hydrothermal veins under high temperatures and pressure. The pink color is caused by microscopic inclusions of a fibrous pink aluminum-borosilicate mineral related to dumortierite.
Uses & applications
Mainly used as gemstones, beads, and cabochons for jewelry making, fashion accessories, ornamental carvings, and lapidary crafts.
Geological facts
Rose quartz has been used in jewelry since as early as 700 BC in Assyria. Unlike regular quartz, rose quartz rarely forms distinct, well-defined single crystal faces.
Field identification & locations
Identified by its characteristic soft pink shade, hardness of 7 (scratches glass), glass-like luster, and absence of cleavage. Found abundantly in Brazil, Madagascar, South Africa, and the United States (South Dakota).
