Physical properties
Hardness of 7 on the Mohs scale, clear to white color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through crystallization from silica-rich fluids and magmas.
Uses & applications
Widely used in electronics, glassmaking, precision instruments, and as gemstones or mineral collector specimens.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness, lack of cleavage, and distinct conchoidal fracture; found globally in nearly all geological settings.
