Physical properties
Hardness of 7 on the Mohs scale, translucent white to pinkish color, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Formed through crystallization from silica-rich solutions or cooling magma, highly resistant to weathering allowing it to survive long transport as a water-worn pebble.
Uses & applications
Used in glassmaking, electronics, abrasives, and as a decorative stone in landscaping and rock tumbling.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electrical charge under mechanical stress.
Field identification & locations
Easily identified in the field by its high hardness which scratches glass and lack of reaction to acid. Commonly found in riverbeds, beaches, and sedimentary deposits worldwide.
