Physical properties
Hardness of 7 on the Mohs scale, clear to white color, vitreous luster, hexagonal crystal system, and conchoidal fracture.
Formation & geological history
Formed from hydrothermal solutions rich in silica, precipitating in cavities or fractures within rocks over millions of years.
Uses & applications
Used in electronics, watchmaking, glassware, and as a popular mineral specimen for collectors and jewelry.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Easily identified by its distinct hexagonal crystal termination and high scratch resistance against glass, commonly found worldwide.
