Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone
Crystal System
Trigonal; typically occurs in massive form, rarely as individual crystals
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2 (Silicon Dioxide) with trace amounts of titanium, iron, or manganese
Formation Process
Igneous formation within granitic pegmatites at high temperatures and pressures through slow cooling of silica-rich magma
About This Crystal
Translucent to semi-opaque with a soft pink to rose-red hue; possesses a vitreous (glass-like) to slightly greasy luster and often contains internal veining or cloudy inclusions
Physical Characteristics
Color: Pale pink to deep rose; Streak: White; Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Usually inert but can show weak purple under LWUV
Optical Properties
Refractive Index: 1.544-1.553; Birefringence: 0.009; Uniaxial (+); may exhibit asterism (six-rayed star) if tiny rutile inclusions are present
Hardness & Durability
Origin Region
Madagascar, Brazil, South Africa, and South Dakota (USA); commonly found in pegmatite cores
Hardness & Durability
Mohs hardness: 7; Toughness: Good (due to lack of cleavage); Stable for daily jewelry wear
