Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, hexagonal crystal system, concoidal fracture, and specific gravity of 2.65.
Formation & geological history
Formed in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich solutions and magmas.
Uses & applications
Widely used in electronics, glassmaking, construction aggregates, countertops, and gemstone jewelry.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, exhibiting piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture.
