Quartz is the second most common mineral in the world. It comes mainly from the earth's continental crust. There are many varieties of quartz, including Amethyst and Citrine. Quartz can come in many different colors. For an example, red quartz is red because there is a large amount of iron in the mineral. This is true for many other rocks. Quartz is not just found in crystal form it is also formed in veins.
