Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. It typically appears white, transparent, or milky with potential grey impurities.
Formation & geological history
Forms in wide varieties of igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich fluids.
Uses & applications
Used extensively in glassmaking, electronics, oscillators, abrasives, and ornamental carvings or jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and conchoidal fracture. It is found worldwide in virtually all geological settings.
