Physical properties
Hardness of 7 on the Mohs scale, white to clear coloration with iron-oxide staining (brown/orange), vitreous luster on crystal faces, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins or cavities within host rock where silica-rich fluids cooled and precipitated over millions of years.
Uses & applications
Used in mineral collecting, lapidary arts, decorative display, and industrial silica applications.
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 electric charge under mechanical stress.
Field identification & locations
Easily identified by its hardness (scratches glass) and crystal formation. Commonly found worldwide in pegmatites, hydrothermal veins, and sedimentary deposits.
