Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, trigonal crystal system, specific gravity of 2.65.
Formation & geological history
Formed in a wide variety of geological environments, commonly in hydrothermal veins, pegmatites, and as a primary constituent of igneous, metamorphic, and sedimentary rocks.
Uses & applications
Used in electronics, glassware, precision instruments, gemstones, and mineral collections.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electrical charge under mechanical stress.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide in almost every geological setting.
