Physical properties
Hardness of 7 on the Mohs scale, colorless or transparent, vitreous (glassy) luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed predominantly from hydrothermal veins, pegmatites, and as a primary constituent of igneous, metamorphic, and sedimentary rocks over millions of years.
Uses & applications
Widely used in electronics (oscillators), optical equipment, gemstone carving, jewelry, and crystal healing.
Geological facts
Clear quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electrical charge when compressed.
Field identification & locations
Identified by its hexagonal crystal form, high hardness (scratches glass), and vitreous luster. Found globally, with notable deposits in Brazil, Arkansas (USA), and Madagascar.
