Physical properties
Hardness of 7 on the Mohs scale, white to clear color, vitreous luster, trigonal crystal system, and conchoidal fracture.
Formation & geological history
Formed when silica-rich hydrothermal fluids precipitate quartz into fractures and faults within pre-existing host rock.
Uses & applications
Used in electronics, glassware, manufacturing, and as mineral specimens for rock and crystal collections.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness, inability to be scratched by a steel knife, and distinctive white vein contrast against darker host rock.
