White Quartz (Snow Quartz)
Quartz var. Snow Quartz (Milky Quartz) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal; typically occurs in massive crystalline form when used for beads, though it naturally forms hexagonal prisms
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2 (Silicon Dioxide) with microscopic fluid and gas inclusions
Formation Process
Hydrothermal or Igneous: Crystallizes from silica-rich fluids in veins or pegmatites at various temperatures
About This Crystal
Translucent to semi-opaque white beads with a waxy to vitreous luster. The 'snowy' or milky appearance is caused by tiny water or gas bubbles trapped during crystal growth.
Physical Characteristics
Color: White to grayish-white; Streak: White; Fracture: Conchoidal; Specific Gravity: 2.65; No fluorescence typically observed under UV light
Optical Properties
Refractive Index: 1.544–1.553; Birefringence: 0.009 (weak); Uniaxial positive; Generally exhibits a soft, diffuse glow when backlit
Hardness & Durability
Origin Region
Brazil, Madagascar, USA, and India; found globally in diverse geological settings
Hardness & Durability
Mohs hardness of 7; high toughness and excellent stability; very durable for daily jewelry wear
Care & Maintenance
Clean with warm soapy water; safe for ultrasonic cleaners; avoid extreme thermal shock; store away from harder stones like sapphire or diamond
Rarity & Value
Common and abundant; low price range; usually natural and untreated, though occasionally dyed to mimic other minerals
Special Characteristics
Characterized by microscopic 'fluid inclusions' that scatter light, creating the characteristic milky or snowy white opacity
Lore & History
Historically used for carving and talismans across various cultures; traditionally associated with clarity, innocence, and the Crown Chakra in holistic practices
