Physical properties
Hardness of 7 on the Mohs scale, clear or white color, vitreous luster, hexagonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of magma or precipitation from silica-rich hydrothermal solutions.
Uses & applications
Widely used in electronics, oscillators, glassmaking, abrasive products, and gemstone jewelry.
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 (scratches glass), lack of cleavage, and conchoidal fracture; found globally in various geological settings.
