Imperial Topaz and Aquamarine: Brazil

Overview

Ron LeBlanc and his team of gem hunters travel to Brazil, home to more gemstones than just about anywhere on the planet. Ron's mission is to find imperial topaz - a stone so rare it is only produced by a single mine in Ouro Preto, Brazil. He's looking for a monster stone: a rock that will cut a 20-carat gem … and he's willing to spend big money to get it.
