I recently purchased a previously owned ring from Kay. Description said Neil lane previously owned 1-1/2carat ring. When I got it there was no Neil Lane stamp visible to me on the ring. Do these wear off? So I took it to a Kay store where they verified the diamond was certified and also that there was a “Magic Glo” inscription on inside of ring. The his report says Neil Lane bridal and describes the ring and has a pic. When I got home and was looking it seems Magic Glo was another ring manufacturer. Not sure if what I got is legit or not
