Physical properties
Hardness of 7 on the Mohs scale, milky white color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from cooling magma in igneous pegmatites and hydrothermal veins, or through regional and contact metamorphism.
Uses & applications
Used widely in glassmaking, electronics, oscillators, and as a popular tumbled stone in jewelry and lapidary arts.
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 high hardness (scratches glass) and lack of cleavage; found globally in nearly all geological environments.
