Where to buy
You can also try shopping online, although really you want to see the diamond before buying it (remember the four C’s). If you are being really brave, try going straight to the source: target the companies that usually sell direct to retailers. For example, Rex Mining Diamond Corporation (rexgerms.com) or you can always try Hatton Garden. Finding those sellers will be a bit harder, but if you are looking for cheap loose diamonds, it might be your best bet. You can contact the jewellery trade association and try to find them that way.
