Some quartz contains various minerals inside. There are rutile needles, tourmaline, amphibole, or chlorite flakes.
Rock Crystal is the most common mineral on Earth. In the world, the most beautiful quartz crystals come from Madagascar, Brasil (Minas Gerais) and the USA (Arkansas). The coloration of some minerals is due to the presence of iron oxide traces, of manganese or because of the inclusion of foreign minerals.
