White Quartz
Quartz var. Milky Quartz · Semi-Precious Gemstone / Jewelry Component
Crystal System
Trigonal, shaped into a cut and polished hexagonal prismatic pendant with a terminated point
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2
Formation Process
Hydrothermal and magmatic crystallization from silica-rich fluids at varying temperatures and pressures
About This Crystal
A polished pendant of milky white quartz, featuring a hexagonal prismatic shape with a terminated pyramidal tip, capped with a silver-colored metal bail. The stone is translucent to opaque with a milky white coloration due to microscopic fluid inclusions
Physical Characteristics
Color is milky white with a white streak. It exhibits a conchoidal fracture, lacks distinct cleavage, has a specific gravity of approximately 2.65, and possesses a vitreous to waxy luster when polished. It is brittle and displays piezoelectric properties
Optical Properties
Uniaxial positive with a refractive index of 1.544 to 1.553, showing weak birefringence of 0.009 and no significant pleochroism
Hardness & Durability
Origin Region
Worldwide, extensively sourced from Brazil, Madagascar, USA, and the Alps, typically forming in pegmatites, hydrothermal veins, and igneous environments
Hardness & Durability
Mohs hardness of 7, excellent durability making it suitable for daily jewelry wear, though it can be scratched by harder minerals like topaz or corundum
Care & Maintenance
Can be safely cleaned with warm soapy water and a soft brush; avoid harsh chemicals, ultrasonic cleaners if inclusions are heavily fractured, and prolonged direct sunlight
Rarity & Value
Common, widely accessible, with very affordable pricing for mass-produced carved jewelry pendants, typically requiring no artificial enhancements
Special Characteristics
Contains microscopic fluid or gas inclusions that cause the milky, cloudy appearance, and exhibits strong piezoelectric and pyroelectric properties
Lore & History
Historically used in various ancient cultures for talismans and tools. In modern crystal healing, it is often associated with the crown chakra, purity, clarity of mind, and amplification of energy, though these are traditional beliefs and not scientific claims
