Physical properties
Hardness of 7 on the Mohs scale, clear to white or yellowish color, vitreous luster, hexagonal crystal system, conchoidal fracture.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of magma or precipitation from silica-rich hydrothermal solutions.
Uses & applications
Used in electronics, glassmaking, abrasives, and as a semi-precious gemstone in jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
