Physical properties
Hardness of 7 on Mohs scale, transparent to white color, vitreous luster, hexagonal crystal system, and conchoidal fracture.
Formation & geological history
Formed through the deposition of silica-rich groundwater within gas cavities in volcanic or sedimentary rocks over millions of years.
Uses & applications
Used in gemstone collection, decorative displays, jewelry, and industrial silica applications.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness, distinctive crystal druse on the interior surface, and lack of cleavage; found globally.
