Physical properties
Hardness of 7 on the Mohs scale, clear to white color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich fluids or cooling magma.
Uses & applications
Widely used in electronics, glassmaking, precision instruments, abrasive materials, and gemstone jewelry.
Geological facts
Quartz is one of the most abundant and varied minerals in Earth's continental crust, existing in numerous crystalline and microcrystalline varieties.
