Physical properties
Hardness of 7 on the Mohs scale, white to off-white color, vitreous luster, cryptocrystalline or microcrystalline structure, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through prolonged water erosion and tumbling of parent quartz or quartzite rocks in riverbeds or marine environments.
Uses & applications
Used primarily in landscaping, decorative garden features, pathway paving, and occasionally in tumbling crafts.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Easily identified by its high hardness which scratches glass and its smooth, rounded shape acquired from aquatic transport. Commonly found in riverbeds worldwide.
