Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and no cleavage. Colors range from colorless to white or yellowish due to iron staining.
Formation & geological history
Formed through the mechanical weathering and water transport of primary quartz veins or silica-rich rocks, accumulating in riverbeds and beaches over geological timescales.
Uses & applications
Used in glassmaking, abrasives, electronics, and as decorative landscape gravel or lapidary material.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and resistance to acid. Common worldwide in alluvial deposits and sedimentary formations.
