Physical properties
Hardness of 7 on the Mohs scale, typically clear or white, vitreous luster, hexagonal crystal system, and conchoidal fracture.
Formation & geological history
Formed through the precipitation from silica-rich hydrothermal solutions or cooling of magma, spanning across various geological ages.
Uses & applications
Widely used in electronics, oscillators, glassmaking, gemstone jewelry, and decorative mineral specimens.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness, lack of cleavage, and distinct hexagonal prism habit; found globally in igneous, metamorphic, and sedimentary rocks.
