Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from cooling magma in hydrothermal veins and pegmatites across diverse geological environments globally.
Uses & applications
Used extensively in electronics for oscillators, precision optics, glass manufacturing, and as a popular gemstone and metaphysical specimen.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its distinct hexagonal crystal habit, lack of cleavage, and ability to scratch glass easily.
