We were looking at loose diamonds - when we saw this one, we knew it was the right one -it just leapt out, and looked a million times better than the others. After we'd chosen it, a look at the cert confirmed that it had good table and depth, so our decision was confirmed.
All our research, help from the internet and slogging around gave us a good idea of what we were looking for - so when we found it, it was obvious.
Without sites like this, we basically wouldn't have had a clue.
So thanks again for all of your help.
