Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, hexagonal crystal system, and transparent to translucent appearance with no cleavage.
Formation & geological history
Formed through the precipitation of silica-rich hydrothermal fluids cooling within rock cavities and fissures over millions of years.
Uses & applications
Widely utilized in jewelry, electronics for oscillation, decorative items, and metaphysical crystal collecting.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its distinct hexagonal prism habit, high hardness that scratches glass, and conchoidal fracture.
