DO NOT DO BUSINESS WITH THESE SCAM ARTISTS! I shipped a ring to sell, only because I received a decent buyback quote in writing. I was told my diamond would NOT be taken out of the setting. When I received a call back offer, I was given an offer of HALF the original quote. I told them I wanted my ring shipped back immediately. I had an agent call me back and berrade me for 10 minutes, yelling because I would not let him soak my diamond in acid, and sell him my ring for 1/4 the appraisal value. The ring was shipped and the BANDS WERE taken apart. My stomach sank! The diamond looks nothing like the diamond I shipped. I now have to file a police report and have my insurance investigate. I called him on the issue and how the diamond looks different and scratched. He said "ya ya, see you in court". IF YOU SEE A US GOLD BUYER AGENT..RUN!
