White Quartz
Quartz (Silicon Dioxide) · Semi-Precious Gemstone and Mineral Specimen
Crystal System
Trigonal, commonly occurs as tumbled pebble or massive habit
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2
Formation Process
Forms primarily through igneous processes in pegmatites, hydrothermal veins, and metamorphic and sedimentary environments
About This Crystal
A tumbled, milky-white to translucent quartz pebble showing internal fracturing, vitreous to waxy luster, and localized earthy matrix inclusions at the base
Physical Characteristics
White to clear body color, white streak, conchoidal fracture, no true cleavage, specific gravity of approximately 2.65, brittle tenacity
Optical Properties
Singly refractive or uniaxial positive with a refractive index around 1.544-1.553, typically transparent to translucent with vitreous luster
Hardness & Durability
Origin Region
Worldwide distribution, notably Brazil, Madagascar, United States, and the Alps; found in various geological settings
Hardness & Durability
Mohs hardness of 7, good durability and resistance to scratching, making it suitable for general jewelry use despite internal fractures
Care & Maintenance
Easy to care for; clean with warm soapy water and a soft brush, avoid harsh chemical acids (hydrofluoric acid) and extreme thermal shock
Rarity & Value
Extremely common mineral with very low commercial value for tumbled specimens, primarily valued for metaphysical uses or decorative purposes
Special Characteristics
May exhibit piezoelectric and pyroelectric properties under mechanical stress or temperature changes
Lore & History
Widely associated in modern crystal healing with clarity, amplification of energy, and the crown chakra, though these are traditional beliefs rather than scientific claims
