Brazil has supplied collectors with wonderful mineral specimens for decades.  The gem material such as tourmaline, aquamarines, and topaz receive most of the acclaim, however there are a great diversity of Brazilian minerals worth noting.  Because we purchase older collections we often have fine examples of Brazilian minerals that are not common in today's contemporary mineral market.
