Physical properties
Mohs hardness of 7, colorless to white, vitreous luster, hexagonal crystal system, conchoidal fracture with no cleavage.
Formation & geological history
Formed through the precipitation of silica-rich hydrothermal fluids in cavities or veins within host rocks over millions of years.
Uses & applications
Used in electronics, frequency control, optics, and decorative gemstone or collector specimens.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness, distinctive crystal shape, and lack of cleavage; commonly found globally in pegmatites and hydrothermal veins.
