Physical properties
Hardness of 7 on the Mohs scale, yellow to brown color due to iron staining, vitreous luster, trigonal crystal system, and conchoidal fracture with no cleavage.
Formation & geological history
Formed through weathering and prolonged water transport of primary quartz veins or pegmatites, smoothing the edges into a rounded pebble.
Uses & applications
Used in landscaping, decorative gravel, tumbling, and as a raw material for silicon extraction.
Geological facts
Quartz is one of the most abundant minerals on Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Identified by its high hardness which scratches glass and lack of reaction to acid. Common in riverbeds, beaches, and glacial deposits worldwide.
