White Quartz
Quartz var. Milky Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically hexogonal prismatic habit, though presented here as a tumbled, massive form
Mineral Group
Silicates (Tectosilicates)
Chemical Formula
SiO2 (Silicon Dioxide) with microscopic fluid or gas inclusions
Formation Process
Primary formation via magmatic crystallization in pegmatites or more commonly through hydrothermal vein deposition
About This Crystal
A translucent to opaque white specimen with a smooth, tumbled finish. It exhibits a greasy to vitreous luster and contains internal fractures and 'milkiness' caused by minute inclusions of gas or liquid trapped during crystal growth.
Physical Characteristics
Color: White to cloudy; Streak: White; Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Usually none; Tenacity: Brittle.
Optical Properties
Refractive Index: 1.544-1.553; Birefringence: 0.009; Optical character: Uniaxial positive; No pleochroism or dispersion is visible in this opaque variety.
Hardness & Durability
Origin Region
Found globally; notable sources include Brazil, USA (Arkansas), Madagascar, and the Alps
Hardness & Durability
Mohs Hardness: 7; Toughness: Good; Highly stable and resistant to most acids and environmental factors, making it excellent for jewelry.
Care & Maintenance
Clean with warm soapy water and a soft brush. Safe for ultrasonic cleaners generally, but avoid extreme thermal shock. Store away from softer stones like fluorite or calcite to prevent scratching them.
Rarity & Value
Common rarity; high availability globally. Value is generally low, based on size and aesthetic appeal. Usually untreated, though sometimes dyed or irradiated for other varieties.
Special Characteristics
Features 'milky' appearance due to fluid inclusions; may exhibit weak piezoelectricity when under mechanical stress.
Lore & History
Historically used for tools and ceremonial objects by nearly every ancient culture. In metaphysical traditions, it is often associated with the Crown Chakra and believed to represent clarity, purity, and the amplification of energy.
