Physical properties
Hardness of 7 on the Mohs scale, typically white, gray, or colorless with a vitreous (glassy) luster. It has a hexagonal crystal system, conchoidal fracture, and no true cleavage.
Formation & geological history
Formed in a wide variety of geological environments, including igneous, metamorphic, and sedimentary rocks, often crystallizing from silica-rich hydrothermal veins or magma.
Uses & applications
Used in electronics, oscillators, glassmaking, abrasive materials, gemstone carving, and decorative specimens.
Geological facts
Quartz is one of the most abundant and widely distributed minerals on Earth's continental crust, known for its piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass), conchoidal fracture, and lack of cleavage. Found worldwide in nearly every geological setting.
