Physical properties

Formation & geological history

Formed in hydrothermal veins, pegmatites, and various igneous, metamorphic, and sedimentary environments over millions of years.

Uses & applications

Used in electronics, frequency control, optics, ornamental carvings, and gemstone collection.

Geological facts

Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electrical charge under mechanical stress.

Field identification & locations

Easily identified by its high hardness (scratches glass), conchoidal fracture, and lack of cleavage. Found worldwide in nearly all geological environments.
