How do you guys feel about buying loose diamonds online? I've seen a lot of good deals out there online but I am very skeptical. Particularly on eBay, an add like this -->http://cgi.ebay.com/1-02-CARAT-D-COL...QQcmdZViewItem<-- seems unlikely for the price. What are your thoughts? I know a good place to look is pawn shops, but what can I expect to pay there?
