Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and typically white, clear, or stained with earthy impurities.
Formation & geological history
Formed through the cooling and crystallization of silica-rich hydrothermal solutions or magma in crustal fractures.
Uses & applications
Used in glassmaking, electronics, oscillator components, and as a decorative or lapidary specimen.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture; found worldwide in veins and pegmatites.
