Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. It typically appears translucent to opaque with variable coloration.
Formation & geological history
Forms in wide variety of environments including igneous, metamorphic, and sedimentary rocks via crystallization from silica-rich fluids.
Uses & applications
Used extensively in glassmaking, electronics, oscillators, abrasives, and as a semi-precious gemstone in jewelry.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified easily by its high hardness (scratches glass) and lack of cleavage; found globally in veins, pegmatites, and sandstones.
