Physical properties
Mohs hardness of 7, white to milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich solutions or magma.
Uses & applications
Used in glassmaking, electronics, oscillators, abrasives, and as a popular lapidary and collector mineral.
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 conchoidal fracture. Found worldwide in veins, pegmatites, and sands.
