Physical properties
Hardness: 7 on Mohs scale; Color: Pink, ranging from pale to deep rose; Luster: Vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Formed in igneous pegmatites and hydrothermal veins during the late stages of magma cooling. Found in various geological ages where felsic igneous rocks comprise the crust.
Uses & applications
Primarily used in jewelry, decorative carvings, lapidary arts, and 'healing' crystal retail industry. Also collected as mineral specimens.
Geological facts
Unlike other varieties of quartz, rose quartz rarely forms well-defined visible crystal faces; it is usually found as massive lumps. The color can fade over time if exposed to too much direct sunlight.
Field identification & locations
Identify by its characteristic pink hue, high hardness (will scratch glass), and lack of cleavage. Common in Brazil, Madagascar, South Africa, and the United States (South Dakota).
