    Sorry to be so late in replying but I've just joined here and I'm
    catching up. 

    One possibility is that the rhodium is not fully reaching into tiny
    recesses around the beadwork. It looks good new but with time the
    gold tarnishes where it hasn't been covered well. A higher voltage
    may help with getting better throw into these areas. 

    if the discoloration is more generalized, affecting the whole piece
    you might consider switching to a different rhodium formulation. If
    you're using acid based now, try a sulfate base. 

Good luck
