Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, colorless to white with dark matrix inclusions, conchoidal fracture, hexagonal crystal system, specific gravity of 2.65.
Formation & geological history
Formed through hydrothermal processes or crystallization from silica-rich solutions within igneous, metamorphic, and sedimentary environments.
Uses & applications
Used in electronics, watchmaking, glass manufacturing, ornamental objects, and as a mineral specimen for collectors.
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 lack of cleavage. Common worldwide in almost all geological environments.
