'''Quartz''' is the most common mineral found on earth. More accurately, Silicon Dioxide, quartz has a chemical composition of SiO<sub>2</sub> arranged in a repeating latice forming [[crystal|crystals]]. If the quartz is pure it would be clear, but the colored variations are created because of impurities in the crystal. | '''Quartz''' is the most common mineral found on earth.
