Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, hexagonal crystal system with no cleavage.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments, highly resistant to weathering allowing it to survive as rounded stream pebbles.
Uses & applications
Used in glassmaking, electronics, abrasives, and as decorative landscape stone or lapidary material.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its high hardness which scratches glass and lack of reaction to acid; found globally in rivers, beaches, and soils.
