Physical properties
Hardness of 7 on the Mohs scale, white to clear color with brownish iron-oxide staining, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed through hydrothermal processes where silica-rich fluids precipitate quartz within fractures and faults of pre-existing rocks under high pressure and temperature.
Uses & applications
Used in glass manufacturing, electronics, gemstones, ornamental objects, and abrasive products.
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 high hardness (scratches glass) and conchoidal fracture. Commonly found globally in pegmatites, hydrothermal veins, and metamorphic rocks.
