Strawberry Quartz
Quartz with Hematite inclusions (Silicon Dioxide) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal; typically found as hexagonal prisms or massive forms; the pictured specimen is carved into a butterfly shape.
Mineral Group
Silicates (Tectosilicate)
Chemical Formula
SiO2 + Fe2O3 (Iron oxide inclusions)
Formation Process
Hydrothermal; forms as quartz crystallizes while trapping tiny flakes or needles of hematite, goethite, or lepidocrocite during growth.
About This Crystal
Translucent pink to reddish-pink quartz with distinct red flecks or 'seeds.' Pictured is a polished butterfly carving with a vitreous luster and visible internal speckling.
Physical Characteristics
Color: Pink to reddish; Streak: White; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Generally none, though inclusions may occasionally react.
Optical Properties
Refractive Index: 1.544–1.553; Birefringence: 0.009; Uniaxial (+); demonstrates aventurescence or a 'sparkle' from plate-like iron inclusions.
Hardness & Durability
Origin Region
Primarily Russia (Kazakhstan), Brazil, and South Africa; found in pegmatites and hydrothermal environments.
Hardness & Durability
Mohs Hardness: 7; tough and durable; resistant to most household chemicals and excellent for daily-wear jewelry.
Care & Maintenance
Clean with warm soapy water; safe for ultrasonic cleaners unless heavily fractured. Avoid long-term exposure to intense direct sunlight which may fade some pink quartz.
Rarity & Value
Uncommon compared to Rose Quartz; value is determined by the density and evenness of 'strawberry' speckling and translucency. Often imitated by glass.
Special Characteristics
Characterized by internal red dots or needle-like inclusions of iron minerals that create a unique reddish-pink speckled aesthetic.
Lore & History
Traditionally associated with the Heart Chakra; believed in spiritual lore to amplify love and gratitude. Historically used for ornamental talismans and decorative carvings.
