Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, transparent to translucent, hexagonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Formed through crystallization from silicate-rich hydrothermal solutions or magmas in diverse geological environments worldwide.
Uses & applications
Widely used in jewelry, electronics, optical components, glass manufacturing, and as a popular collector specimen.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Identified by its distinct crystal habit, high hardness that scratches glass, and lack of cleavage; commonly found globally in pegmatites, hydrothermal veins, and sedimentary rocks.
