quartz
Silicon dioxide crystal
Quartz is a hard, crystalline mineral composed of silicon and oxygen—one of the most abundant minerals in Earth's crust.
It occurs in many varieties, from clear rock crystal to colored forms like amethyst and citrine.
Quartz is prized in jewelry, used in electronics for its piezoelectric properties, and appears in everyday materials like glass and concrete.
A quartz watch or clock uses a vibrating crystal to keep precise time.
