Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, hexagonal crystal system, and colorless to yellowish-brown coloration due to iron oxide inclusions.
Formation & geological history
Formed through the precipitation of silica-rich hydrothermal solutions cooling within cavities of host rocks over millions of years.
Uses & applications
Used in electronics, oscillator frequency control, decorative display, and gemstone carving.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its high hardness, lack of cleavage, and distinct hexagonal crystal terminations; commonly found worldwide in pegmatites and hydrothermal veins.
