Physical properties
Hardness of 7 on the Mohs scale, white to translucent color with a dark fracture line, vitreous luster, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed via hydrothermal precipitation in cracks and fissures within the Earth's crust under high pressure and temperature over millions of years.
Uses & applications
Used in decorative landscaping, specimen collecting, and occasionally crafted into ornamental items or carvings.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness, which easily scratches glass, and its smooth water-worn surface typical of river pebbles.
