Hi: I brought a diamond, which had been my mother's, to a jeweler to have it reset and polished. When I went to pick it up, they showed me the diamond had been returned and said there was a problem when it was polished and it was now very cloudy and they were going to send it back to be re-polished. I asked another jeweler and they said that a diamond like that cannot be ever be repaired. Is this true and what options do I have with the jeweler. Thanks for any help!
