Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, hexagonal crystal system, specific gravity of 2.65.
Formation & geological history
Formed in a wide range of geological environments, frequently in hydrothermal veins, pegmatites, and as a primary component of sedimentary and igneous rocks over millions of years.
Uses & applications
Used in electronics, glassware, jewelry, and as decorative landscape or ornamental stones.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust, surpassed only by feldspar.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture. Commonly found worldwide in almost all rock types.
