Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent color, vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms globally in hydrothermal veins, pegmatites, and metamorphic environments over millions of years from silica-rich fluids.
Uses & applications
Carved into decorative items, luxury chess sets, and gemstones due to its optical clarity and durability.
Geological facts
Ancient civilizations believed rock crystal was permanently frozen celestial ice. Clear quartz exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Identified by its extreme hardness, cold touch, and lack of double refraction; crafted quartz pieces are often polished to accentuate transparency.
