Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and trigonal crystal system with various colors including clear, white, yellow, and brown.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich fluids at various temperatures and pressures.
Uses & applications
Used in electronics, glassmaking, abrasives, gemstones, and ornamental carvings.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties, making it essential for accurate timekeeping in watches.
Field identification & locations
Identified easily by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture; commonly found worldwide in pegmatites, veins, and sandstones.
