    I haven't tried those discs so I looked them up in the Rio book.
    They describe the abrasive as "cubitron mineral abrasive much harder
    than most metals". Dunno for sure but that sounds pretty aggressive. 

    If the damage you note is to the stones, then I would say the discs
    are the problem. Use pumice if you have to have a firmish wheel. Use
    china bristle brush with compound if you need to get into crevices. 

    A word about polishing with any kind of brush(some cloth wheels
    too)...you must keep the wheel in sideways motion as relates to
    object or you will most likely cut grooves into the metal. And if
    feasible alter your angle of attack frequently. Drag lines. hrumph! 

    It would be nice if tools suppliers listed the hardness of abrasives
    and suitability for various stones. 

    Prepolishing is fine when its appropriate. I don't know that I'd get
    too fanatical about removing every imperfection at each step. Your
    surface is going to be affected by subsequent handing anyway. 

    Yes, I agree with..umm now I forgot who said it...only light
    polishing after setting. If for some reason you absolutely HAD TO
    heavy polish around set stones with an aggressive abrasive, you
    might try crazy gluing small domed discs over the stones but you'd
    want to cover the bezel edge too I should think.
