Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, white to translucent color, and conchoidal fracture.
Formation & geological history
Formed through mechanical weathering and aqueous transport of primary igneous or metamorphic quartz veins.
Uses & applications
Used in landscaping, decorative gravel, glassmaking, and abrasive manufacturing.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust, surviving multiple cycles of erosion.
Field identification & locations
Easily identified by its high hardness, lack of cleavage, and resistance to weathering in stream beds worldwide.
