Physical properties
Hardness of 7 on the Mohs scale, white to clear color, vitreous luster, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed through the mechanical weathering and prolonged aqueous transport of quartz veins or igneous rocks.
Uses & applications
Used in landscaping, decorative stone, abrasive manufacturing, and polished lapidary specimens.
Geological facts
Quartz is one of the most abundant and resistant minerals on Earth's surface, allowing it to survive extensive transport.
Field identification & locations
Found in stream beds and beaches worldwide; identified by its high hardness, inability to be scratched by steel, and lack of cleavage.
