Quartz (Silica var. Milky/Clear Quartz with Inclusions) · Mineral Specimen / Semi-Precious
Crystal System
Trigonal system, massive to blocky unformed crystal habit
Mineral Group
Silicates (Tectosilicates)
Chemical Formula
SiO2
Formation Process
Hydrothermal and pegmatitic crystallization from silica-rich aqueous solutions at moderate to high temperatures and pressures
About This Crystal
Small, angular rough mineral specimen resting on an open palm, exhibiting a milky-white body color with translucent to semi-transparent sections and minor darker surface mineral inclusions
Physical Characteristics
White streak, no true cleavage, conchoidal fracture, specific gravity of approximately 2.65, brittle tenacity, vitreous luster
Optical Properties
Singly refractive or uniaxial positive with low birefringence, no pleochroism
Hardness & Durability
Origin Region
Worldwide distribution; commonly found in pegmatites, hydrothermal veins, and metamorphic rocks
Hardness & Durability
Mohs hardness of 7, good durability and toughness, suitable for daily jewelry wear with proper setting
Care & Maintenance
Clean with warm soapy water and a soft brush, store separately to avoid scratching softer stones, highly resistant to common household chemicals
Rarity & Value
Very common mineral, low monetary value for rough small specimens, widely available globally
Special Characteristics
May exhibit piezoelectric and pyroelectric properties under mechanical stress or temperature changes
Lore & History
Quartz has been used since antiquity for tools, ornaments, and in traditional crystal healing practices to promote clarity, energy amplification, and spiritual balance, though these are cultural beliefs rather than scientific facts
