Physical properties
Hardness of 7 on Mohs scale, typically white or colorless, vitreous luster, hexagonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich solutions or cooling magmas.
Uses & applications
Widely used in electronics, glassmaking, abrasives, and as a semi-precious gemstone in jewelry.
Geological facts
Quartz is one of the most abundant and ubiquitous minerals found in the Earth's continental crust.
