Quartz is a crystalline mineral of silicon dioxide, also referred to as Crystalline Silica. Quartz is the most abundant mineral on the earth's surface and the second most abundant mineral in the earth's crust. Beach and desert sand is primarily composed of quartz crystals due to quartz's high resistance to mechanical and chemical weathering.
