[Jewelry making - Article 00456] - [Orchid] Rhodium Plating and diamonds black reflection

    What causes the diamonds to have a black reflection on some of the
    pieces we rhodium plate? The peice is cleaned and checked under 60
    power to be certain it is clean. This has happened a couple of times
    in the past few months. There does not seem to be any way to remove
    the "shadow" once it is there. How do we avoid this? 

    We try to buff off any plating on the outside of the ring, but
    obviously can not get into the seats or channels of the stones. 

    This "shadow" will not come off from steam, ultra sonic, amonia,
    acetone, or anything we can think of. 

Any suggestions?
