Quartz - Wikipedia
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).The atoms are linked in a continuous framework of SiO 4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.. Quartz exists in two forms, the normal α-quartz,Quartz Value, Price, and Jewelry Information,,Milky Quartz The milkiness is due to myriad tiny cavities and bubbles filled with CO 2 or water.
