Happy Mother's Day!
No....it does not help. Uncertified diamonds are like fake designer handbags. They may pass to ordinary people as something nice, but they are not worth what you paid for them. Ask yourself why the diamonds are not certified? It's because they will come back as poor cut quality and they will have to adjust the price down accordingly. If they were well cut diamonds and the company thought so then they would offer to send them to GIA or AGS and certify them....not an independent appraiser. That's worthless. Trust me. Good old gold cuts ideal cut diamonds. They know what they look like. I'm not trying to bash good old gold. I have an AMAZING August vintage cushion from them and love it. It's also certified because they know it's a beautifully cut stone and worth the extra few hundred dollars to certify it. Clearly these diamonds are not worth their money to certify them. So personally, I would not want them.
I have bought diamonds from whiteflash, good old gold, Brian Gavin, and Victor Canera. I really like all 4 companies. However, I will not buy a diamond over a quarter carat uncertified. Ever. Out of these 4 companies, I think whiteflash is the best for studs due to there large inventory and amazing upgrade policy.
