Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, hexagonal crystal system, and lack of cleavage.
Formation & geological history
Formed from hydrothermal solutions in rock cavities and veins across a wide range of geological ages.
Uses & applications
Widely used in electronics, oscillator circuits, gemstone carving, and mineral collecting.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness, characteristic crystal shape, and conchoidal fracture, found globally in pegmatites and sedimentary rocks.
