Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling and precipitation of silica-rich solutions over millions of years.
Uses & applications
Widely used in electronics, oscillator clocks, glass manufacturing, and as a popular gemstone or mineral specimen for collectors.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, meaning it generates an electrical charge when compressed.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and characteristic hexagonal crystal forms or irregular shards.
