This site is really great!!! (5 stars!) for VerifiedBuy.com

I tried to buy loose diamonds and looking for a very specific stones just a couple of weeks ago (i.e- size, color, price, certification etc...) and it was easy to navigate in it. I found what I want in no time (especially comparing other sites).
they also suggest low & atractive price quote of their goods.
Moreover, when I needed help I've got fast and professional reply. It was a very good costumer service.

i contacted theirs live chat .
it was at 0200 am
and got human support
it was very nice and easy to complete buying my loose diamonds (round diamond)
