Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, hexagonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through cooling magmas or precipitation from hydrothermal solutions over millions of years.
Uses & applications
Widely used in electronics, glassmaking, jewelry, and decorative carvings due to its piezoelectric properties and durability.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectricity, generating an electric charge under mechanical stress.
Field identification & locations
Identified by its high hardness, lack of cleavage, and distinct conchoidal fracture; commonly found globally in pegmatites, veins, and sandstones.
