This Friday is the season finale of "Game of Stones" (airing April 4 at 10:00 p.m. on Discovery), and it's good news (maybe) for our intrepid miners. After getting duped during a deal for Blue Turk, Don and the Gem Guys salvage their botched mission by trekking into the foothills of Turkey. While the bad news is that they face an abandoned mine that could collapse at any time, the good news is that it may totally be worth it. In this exclusive clip, sees what happens when they stumble upon what looks (at  least, to the untrained eye) like a bunch of shiny rock. 

If you haven't been watching, Don Kogen, America's most extreme gem hunter and the CEO of Gem Guys, Inc., is a legend in the business, and I guess finds like this one are part of the reason. He specializes in rare stones from the most dangerous and lawless places on earth, racing the clock to be the first to each new find. To make matters worse (or at least riskier), he and his crew carry large amounts of cash, so they are at constant risk of being robbed, car jacked and ambushed. But they are prepared, at all times, to protect their rocks and their lives. 

Are you ready for the finale of "Game of Stones"?
