Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone
Crystal System
Trigonal; typically found in massive form, though rare prismatic crystals exist
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2 (Silicon Dioxide) with trace amounts of titanium, iron, or manganese causing the pink color
Formation Process
Magmatic crystallization in pegmatites, also found in hydrothermal veins; forms under relatively high temperatures as granitic magma cools
About This Crystal
Translucent to transparent pink hue ranging from pale blush to deep rose; vitreous luster with a cloudy or 'milky' appearance due to microscopic needle-like inclusions of dumortierite
Physical Characteristics
Color: soft pink; Streak: white; Cleavage: none; Fracture: conchoidal; Specific Gravity: 2.65; Fluorescence: weak to non-existent
Optical Properties
Refractive Index: 1.544-1.553; Double refraction (uniaqual positive); Birefringence: 0.009; Weak pleochroism in deeply colored specimens
Hardness & Durability
Origin Region
Notable sources include Brazil, Madagascar, South Africa, and the United States (South Dakota)
Hardness & Durability
Mohs Hardness: 7; excellent durability for jewelry; brittle tenacity with no cleavage planes making it resistant to chipping
Care & Maintenance
Clean with warm soapy water; avoid prolonged exposure to direct sunlight as colors may fade; safe for most jewelry use but sensitive to hydrofluoric acid
Rarity & Value
Common and readily available; value is dictated by color saturation and transparency; rare transparent specimens command higher prices
Special Characteristics
Can exhibit asterism (a six-rayed star effect) when cut into cabochons due to aligned rutile or dumortierite inclusions; usually semi-translucent due to microscopic fibers
Lore & History
Known historically as the 'Stone of Love'; long used as a talisman for relationships. In Egyptian and Roman cultures, it was believed to clear the complexion and prevent wrinkles.
