Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 siliconoxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Since antiquity, varieties of quartz have been the most commonly used
