Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and white to yellowish coloration.
Formation & geological history
Formed via the weathering and aqueous transport of quartz veins or igneous rocks over millions of years.
Uses & applications
Used in landscaping, decorative items, and occasionally polished for simple jewelry.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust.
Field identification & locations
Identified by its high hardness (scratches glass) and lack of cleavage; found globally in rivers and beaches.
