Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from cooling magma in igneous pegmatites or precipitating from hydrothermal solutions in various geological environments over millions of years.
Uses & applications
Widely used in electronics for oscillators, glass manufacturing, abrasives, and ornamental jewelry or crystal specimens.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties, generating electricity under mechanical stress.
Field identification & locations
Easily identified by its distinct hexagonal crystal habit and high hardness that scratches glass. Found worldwide in nearly all geological environments.
