Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, colorless to greyish with dark mineral inclusions, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins and pegmatites, cooling from silica-rich solutions over millions of years.
Uses & applications
Used in electronics, gemstone carving, decorative items, and mineral collecting.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and conchoidal fracture; found worldwide in various geological settings.
