Physical properties
Hardness of 7 on the Mohs scale. White to translucent color with a vitreous luster and conchoidal fracture.
Formation & geological history
Formed from hydrothermal solutions precipitating silica within fractures of host rock over various geological timescales.
Uses & applications
Used in glassmaking, electronics, abrasives, and decorative lapidary work.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its high hardness, lack of cleavage, and conchoidal fracture; commonly found worldwide in hydrothermal veins.
