White Quartz
Quartz var. Milky Quartz · Mineral Specimen and Semi-Precious Stone
Crystal System
Trigonal system, massive or crystalline habit
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2
Formation Process
Igneous, metamorphic, and hydrothermal processes. Crystallizes from silica-rich aqueous solutions at various temperatures and pressures.
About This Crystal
An opaque to translucent white, roughly tumbled or naturally broken chunk of quartz. It exhibits a vitreous to greasy luster, milky white coloration due to microscopic fluid inclusions, and irregular fracture surfaces.
Physical Characteristics
White body color, white streak, conchoidal to uneven fracture, no true cleavage, specific gravity of approximately 2.65, brittle tenacity, and piezoelectric properties.
Optical Properties
Uniaxial positive optical character, refractive index of 1.544 to 1.553, birefringence of 0.009, generally non-pleochroic due to its white/milky appearance.
Hardness & Durability
Origin Region
Found worldwide; notable deposits in Brazil, Madagascar, USA, and the Alps. Forms in diverse geological environments.
Hardness & Durability
Mohs hardness of 7, good durability and wearability for jewelry use, though massive specimens can fracture upon heavy impact.
Care & Maintenance
Can be cleaned safely with warm soapy water. Avoid harsh chemicals and sudden thermal shock. Safe from fading in normal sunlight.
Rarity & Value
Extremely common worldwide, very affordable and accessible as mineral specimens or tumbled stones.
Special Characteristics
Displays microscopic fluid and gas inclusions that cause the characteristic milky white turbidity (milkiness). Exhibits piezoelectricity under mechanical stress.
Lore & History
Historically used by ancient civilizations for tools, ornaments, and ritual objects. In modern metaphysical practices, white quartz is regarded as a master healer stone associated with clarity, purification, and the crown chakra.
