Formation & geological history

Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich magma or precipitation from hydrothermal fluids. Quartz is one of the most common minerals in the Earth's crust.

Uses & applications

Extensively used in electronics for its piezoelectric properties, glass manufacturing, abrasives, jewelry, and as a popular metaphysical or decorative collector's item.

Geological facts

Quartz is one of the most abundant minerals on Earth. It is famous for its piezoelectric property, meaning it generates an electric charge in response to applied mechanical stress, which is why it is used in watches.

Field identification & locations

Look for a hexagonal prism shape terminating in a six-sided pyramid. Quartz will scratch glass and lacks cleavage planes. Common locations include Brazil, USA (Arkansas), and the Alps.
