Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Forms in virtually all geological environments through crystallization from silicate melts or hydrothermal solutions, often rounded by water action in streams and beaches.
Uses & applications
Used in glassmaking, electronics, abrasives, and as a decorative landscaping stone.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and resistance to chemical weathering, commonly found worldwide in gravel bars and shorelines.
