Many factors are involved in purchasing rough gems. I always suggest everyone to buy rough gemstones with the help of a Gem-Cutter or with a person who has the knowledge of buying rough gems. If you don’t have the knowledge do not take a chance, its too risky. you could end up loosing 100’s if not 1000’s of Dollars. You need to watch out for the Bad Dealers, They will try to sell you wrong rough gemstones. Always find out the selling price of faceted gems before making the purchase
