Physical properties
Hardness of 7 on the Mohs scale, white to milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, and specific gravity of 2.65.
Formation & geological history
Formed through crystallization from silica-rich hydrothermal solutions or magmas, subsequently weathered, transported, and rounded by water action in riverbeds or marine environments.
Uses & applications
Used in landscaping, aggregate for construction, abrasive manufacturing, and as a raw material for glass and silicon production.
Geological facts
Quartz is one of the most abundant and durable minerals in the Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage, commonly found in streambeds, beaches, and alluvial deposits worldwide.
