I purchased a customized diamond semi mount from this eBay seller. After approving the CAD design, the ring arrived in the wrong proportions. I sent it back in July and it's now November and I still haven't received my $400 refund. They are in China and claim not to have received the return. I have exhausted all eBay and PayPal resolution options, to no avail. I would advise potential buyers of diamondjewelry8 to beware of this seller. My experience with them has been terrible.
