Clear Quartz
Silicon Dioxide var. Clear Quartz · Semi-Precious Gemstone and Mineral Specimen
Crystal System
Trigonal system, typically forming hexagonal prisms terminated by hexagonal pyramids
Mineral Group
Silicates, specifically Tectosilicates
Chemical Formula
SiO2
Formation Process
Hydrothermal and igneous crystallization, precipitating from silica-rich aqueous solutions at various temperatures and pressures
About This Crystal
A faceted pendulum made of transparent to translucent clear quartz, featuring internal fractures or inclusions near the top and a polished, cut facet structure culminating in a sharp point. Attached to a decorative silver-toned metal cap featuring a pentagram and crescent moon symbols
Physical Characteristics
Colorless, white streak, conchoidal fracture, no true cleavage, specific gravity of approximately 2.65, brittle tenacity, piezoelectric and pyroelectric properties, generally inert under UV light
Optical Properties
Singly refractive optically uniaxial positive, refractive index of 1.544 to 1.553, low birefringence of 0.009, vitreous luster
Hardness & Durability
Origin Region
Global distribution with major commercial sources in Brazil, Madagascar, the United States, and the Himalayan region; forms in diverse geological settings
Hardness & Durability
Mohs hardness of 7, making it durable for daily wear, resistant to scratching by most common materials except harder minerals like topaz and corundum
Care & Maintenance
Can be safely cleaned with warm soapy water and a soft brush; avoid harsh acids, extreme thermal shock, and prolonged direct sunlight if dyed or treated
Rarity & Value
Common, widely accessible and affordable, with value determined by clarity, size, cut, and any special inclusion types
Special Characteristics
Displays natural piezoelectricity, and cut specimens may exhibit internal inclusions, veils, or rainbows (iris quartz) when exposed to light
Lore & History
Historically revered across ancient civilizations as a stone of power, clarity, and spiritual awakening; widely utilized in modern metaphysical practices as a master healer stone associated with all chakras and amplification of energy
