Physical properties

Hardness: 7 on Mohs scale; Color: Pink, pale rose, to reddish-brown (from iron/hematite staining); Luster: Vitreous to greasy; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & geological history

Forms in igneous pegmatites and hydrothermal veins. The pink color is generally attributed to microscopic inclusions of a fibrous pink mineral, likely a borosilicate, while the reddish surface stains are iron oxide deposits (Hematite/Limonite).

Uses & applications

Commonly used in lapidary work for cabochons, beads, and carvings. It is also a popular specimen for crystal healing practitioners and mineral collectors.

Geological facts

Unlike large crystals of clear quartz, rose quartz rarely forms well-defined crystal faces and usually occurs as massive chunks. It is the state rock of South Dakota in the United States.

Field identification & locations

Identify by its waxy-to-glassy luster, conchoidal (shell-like) fracture, and inability to be scratched by a steel knife. Look for it in pegmatite-rich regions like Brazil, Madagascar, or the Black Hills of South Dakota.
