Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, colorless to brown due to iron staining.
Formation & geological history
Formed via intense weathering and water transport of igneous or metamorphic rocks over millions of years.
Uses & applications
Used in landscaping, decorative aggregates, and abrasive manufacturing.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust.
Field identification & locations
Identify by its high hardness, inability to be scratched by steel, and smooth, water-worn shape found in riverbeds and beaches.
