Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments, often shaped by water transport over millions of years.
Uses & applications
Used in glassmaking, electronics, abrasive materials, and as an ornamental or lapidary specimen.
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
Easily identified by its high hardness, lack of cleavage, and resistance to scratching by steel. Common worldwide in riverbeds, beaches, and soil.
