Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from cooling magma in hydrothermal veins and pegmatites, found across a wide range of geological ages worldwide.
Uses & applications
Used widely in electronics, glassmaking, engineered countertops, and as lapidary specimens for carving and jewelry.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its lack of cleavage, high hardness that scratches glass, and distinct conchoidal fracture.
