Physical properties
Hardness of 7 on the Mohs scale, colorless or white, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms from silica-rich hydrothermal veins and pegmatites, crystallizing as temperatures and pressures drop over millions of years.
Uses & applications
Used in electronics, oscillators, glassmaking, optical lenses, jewelry, and spiritual crystal collecting.
Geological facts
Clear quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its distinct hexagonal prism shape, striations, high hardness, and lack of cleavage; commonly found worldwide in igneous, metamorphic, and sedimentary rocks.
