Physical properties
Hardness of 7 on Mohs scale. Colors vary widely including clear, white, yellow, and brown. Exhibits vitreous luster and trigonal crystal structure with conchoidal fracture.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through precipitation from silica-rich solutions or crystallization from magma.
Uses & applications
Used extensively in electronics, glassmaking, oscillators, and as a popular gemstone or collector mineral.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust. It exhibits piezoelectric properties, making it vital for modern timekeeping and electronics.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and distinct conchoidal fracture. Found worldwide in nearly every geological environment.
