The ring I got for my mother's 90th birthday has a 'diamond' which is very very cloudy - dull with no sparkle to it. Diamond? The gold looks much thinner than shown here. The gold also has dark brown stains on it on the inside. I had informed them why I wanted the ring beforehand and this is what they sent me. Needless to say, I want a refund. I hate buying valuable items blind. To make this work companies have to be clear and open about the items they sell.
Edit: the company did make a full refund without quibble.
