Rose Quartz
Quartz variety Rose Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically occurs in massive form, rarely as individual crystals
Mineral Group
Silicates (Tectosilicate)
Chemical Formula
SiO2 (Silicon Dioxide) with trace amounts of Titanium, Iron, or Manganese
Formation Process
Primary crystallization from late-stage cooling of granitic pegmatites and hydrothermal veins
About This Crystal
A translucent to nearly opaque variety of quartz with a pale pink to rose-red hue. It features a vitreous to waxy luster and often contains microscopic fibrous inclusions which produce a cloudy appearance.
Physical Characteristics
Pink body color with a white streak; no cleavage; conchoidal fracture; specific gravity 2.65; brittle tenacity; non-magnetic; may show weak fluorescence.
Optical Properties
Refractive index of 1.544-1.553; uniaxial positive; weak pleochroism; some specimens exhibit asterism (star effect) due to rutile inclusions.
Hardness & Durability
Origin Region
Notable sources include Brazil (Minas Gerais), Madagascar, South Africa, and the United States (South Dakota)
Hardness & Durability
7 on the Mohs scale; good toughness; stable under normal conditions but color can fade if exposed to extreme heat or prolonged direct sunlight.
Care & Maintenance
Clean with warm soapy water; avoid ultrasonic or steam cleaners if the specimen has significant internal fractures; store away from direct sunlight and harder gemstones.
Rarity & Value
Abundant and common; value is determined by color intensity and transparency; higher quality specimens from Madagascar often command higher prices.
Special Characteristics
Notable for its hazy transparency and potential for asterism (six-rayed star effect) when cut into cabochons.
Lore & History
Known historically as the 'Stone of Love'; used in ancient Egyptian and Roman civilizations for talismans. Traditionally associated with the Heart Chakra and emotional healing.
