Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone
Crystal System
Trigonal; typically occurs in massive form, rarely as individual crystals (euhedral crystals are called Pink Quartz)
Mineral Group
Silicates (Tectosilicate)
Chemical Formula
SiO2 (Silicon Dioxide) with trace amounts of Titanium, Iron, or Manganese
Formation Process
Magmatic; forms during the final stages of cooling in granitic pegmatites or occasionally in hydrothermal veins
About This Crystal
Translucent to hazy pink teardrop-shaped cabochon with a vitreous luster. Shows internal fractures and a cloudy appearance due to microscopic fibrous inclusions.
Physical Characteristics
Color remains pale pink to rose red; streak is white; no cleavage; conchoidal fracture; specific gravity of 2.65; weak fluorescence under UV
Optical Properties
Refractive index: 1.544–1.553; double refraction (uniaxial positive); may exhibit asterism (star effect) when cut as a sphere or high cabochon
Hardness & Durability
Origin Region
Brazil (Minas Gerais), Madagascar, South Africa, and USA (South Dakota); found in granitic pegmatites
Hardness & Durability
Mohs hardness 7; high durability and toughness; no cleavage makes it excellent for jewelry use; stable but may fade under extreme heat
Care & Maintenance
Safe to clean with warm soapy water; ultrasonic cleaners are generally safe unless heavily fractured; keep away from prolonged direct sunlight to prevent fading
Rarity & Value
Common and abundant; value is determined by color saturation and transparency; usually untreated, though some may be dyed or irradiated
Special Characteristics
Can show a six-rayed star (asterism) due to rutile silk; exhibits 'tyndall scattering' which gives it the characteristic hazy appearance
Lore & History
Historically used in ancient Egypt and Rome as facial masks for beauty; traditionally known as the 'Stone of Unconditional Love' and associated with the Heart Chakra
