Physical properties
Hardness of 7 on the Mohs scale, yellowish-orange to brownish color, vitreous to waxy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65
Formation & geological history
Forms from silica-rich solutions precipitating in cavities or voids within rocks over millions of years, often found in sedimentary or volcanic environments
Uses & applications
Used in lapidary arts, jewelry making, ornamental carvings, and as a mineral specimen for collectors
Geological facts
Quartz is one of the most abundant minerals on Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electrical charge when compressed
Field identification & locations
Can be identified in the field by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture. Commonly found in riverbeds, beaches, and gravel deposits
