Physical properties
Hardness of 7 on the Mohs scale, typically colorless or grey, vitreous luster, hexagonal crystal system, and no cleavage.
Formation & geological history
Forms hydrothermally from silica-rich fluids cooling in cavities or veins within Earth's crust over millions of years.
Uses & applications
Used in electronics, oscillators, glassmaking, and valued globally as a collector and decorative specimen.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its distinct hexagonal crystal habit and high scratch resistance, commonly found worldwide in pegmatites and hydrothermal veins.
