Physical properties
Hardness of 7 on the Mohs scale, typically white or clear, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms in virtually all geological environments through the crystallization of silica-rich fluids in hydrothermal veins, igneous pegmatites, and sedimentary rocks.
Uses & applications
Widely used in electronics, glassmaking, abrasive powders, and ornamental jewelry or crystal collecting.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Easily identified by its hardness (scratches glass), lack of cleavage, and six-sided crystal habits when well-formed. Commonly found worldwide.
