Imperial Topaz and Aquamarine: Brazil

Gem Hunt – Season 1

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.
