Physical properties
Hardness of 7 on the Mohs scale, clear to translucent color, vitreous luster, hexagonal crystal system, conchoidal fracture, specific gravity of 2.65
Formation & geological history
Formed through hydrothermal processes, where silica-rich fluids cool and crystallize in cavities or fractures within host rocks over millions of years
Uses & applications
Used in electronics, oscillators, gemstones, 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, meaning it can generate an electrical charge under mechanical stress
Field identification & locations
Easily identified by its distinct crystal faces, high hardness (scratches glass), and conchoidal fracture; found worldwide in pegmatites, hydrothermal veins, and sedimentary rocks
