Quartz from Brazil deserves a book of its own, or even an entire library of its own! It is simply impossible to know of all the varieties that exist. There is such a diverse wealth of Quartz in Brazil that it would require lifetimes of study. Brazil is perhaps the most important places on Earth for Quartz, as there is more of it that comes from there than anywhere else, and not just in quantity but in diversity!
Brazil is the one country that has the largest network of specimen and gem mining in the world. It is well known for many of the world's best pegmatites, producing high class Gem Crystals. Brazil has the widest variety of multi-colored Tourmaline worldwide, and is semi-regularly producing new colors every few years. The vast array of Quartz varieties from Brazil deserve a book of their own.
