Where can I go to buy a rough diamond?

I’m interested in uncut diamonds, for collection, not for business purposes. Where can I go, and how will I know that the diamonds are legitimate?

You are not going to find one cheap. Here is one web source: http://roughdiamondworld.com/ another, that is cheaper, is for the stones found in Arkansas Crater of Diamonds State Park: http://www.diamondsinar.com/ Hope they help.
