Physical properties
Hardness: 7 on Mohs scale; Color: Pale pink to tan/white; Luster: Vitreous to waxy; Crystal Structure: Hexagonal (trigonal); Conchoidal fracture.
Formation & geological history
Formed in pegmatites and hydrothermal veins. The pink color is generally attributed to trace amounts of titanium, iron, or manganese, or microscopic mineral inclusions of a pink variety of dumortierite.
Uses & applications
Mainly used for lapidary work, jewelry (beads, cabochons), meditation stones, and metaphysical collecting.
Geological facts
Unlike other quartz varieties, rose quartz rarely forms well-defined crystal faces and usually occurs in massive crystal aggregates. It is the state mineral of South Dakota.
Field identification & locations
Identify by its characteristic hardness (will scratch glass), greasy/vitreous luster, and conchoidal (shell-like) fracture. Commonly found in Brazil, South Africa, and Madagascar.
