Physical properties
Hardness of 7 on Mohs scale, colorless to transparent, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms primarily from hydrothermal veins, pegmatites, and igneous or metamorphic rocks as silica-rich fluids cool and crystallize over millions of years.
Uses & applications
Widely used in electronics for oscillators, precision optics, glassmaking, gemstone carving, and metaphysical crystal collecting.
Geological facts
Clear quartz is the most abundant mineral found at Earth's continental surface and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its hardness of 7, lack of cleavage, and vitreous luster; found globally with major deposits in Brazil, the USA, and Madagascar.
