Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, conchoidal fracture, and no cleavage.
Formation & geological history
Formed via crystallization in hydrothermal veins or igneous rocks, subsequently weathered and water-worn into a smooth pebble over geological timescales.
Uses & applications
Used in glassmaking, electronics, abrasives, and as decorative gravel or tumbled lapidary stones.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified in the field by its high hardness, lack of cleavage, and resistance to chemical weathering.
