Physical properties
Hardness of 7 on Mohs scale, white to translucent color, vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the mechanical weathering and prolonged aqueous transportation of parent igneous or metamorphic rocks, typically found in riverbeds and beaches.
Uses & applications
Used in landscaping, decorative items, glass manufacturing, and as a durable aggregate in construction.
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 smooth water-worn shape. Found worldwide.
