White Quartz
Quartz var. Milky Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal, typically forming as tumbled or massive smooth stones in this presented state
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2
Formation Process
Hydrothermal and igneous pegmatitic crystallization from silica-rich solutions at varying temperatures and pressures
About This Crystal
A small, smoothly tumbled white to milky quartz stone featuring translucent to opaque areas, a waxy to vitreous luster, and smooth rounded edges from tumbling/polishing
Physical Characteristics
Color is milky white; white streak; no true cleavage; conchoidal fracture; specific gravity around 2.65; brittle tenacity; exhibits piezoelectricity
Optical Properties
Uniaxial positive, doubly refractive with a refractive index of approximately 1.544 to 1.553, low birefringence
Hardness & Durability
Origin Region
Global distribution; notable sources include Brazil, Madagascar, United States, and the Alps
Hardness & Durability
Mohs hardness of 7; good durability and toughness, making it highly wearable for jewelry despite lacking cleavage
Care & Maintenance
Safe to clean with warm soapy water; avoid harsh chemical acids (except hydrofluoric); store separately from harder stones like corundum or diamond to avoid scratching
Rarity & Value
Very common and widely accessible; inexpensive, usually sold as tumbled stones or low-cost mineral specimens with minimal or no treatments needed
Special Characteristics
Contains microscopic fluid or gas inclusions that cause the milky-white scattering of light (turbidity); piezoelectric and pyroelectric properties
Lore & History
Historically used across many ancient cultures for amulets and tools; in modern metaphysical practices, white quartz is associated with clarity, purification, and balancing all chakras, though these are traditional beliefs rather than scientific claims
