    The advantages are manifold, but it really depends on what you are
    doing. 

    Before you solder the piece must be clean. If you're making from
    scratch your material is probably already clean enough. If you are
    repairing or making additional solders after polishing you must clean
    completely. Buffing compound can get jammed into tiny recesses, life
    gunk builds up behind stones. Heat a dirty diamond and see what
    happens. It turns stubbornly black. Sometimes you can clean it by
    heating in a heavy coating of Handi-Flux and pickling...sometimes. 

    An ultrasonic will clean without scratching your laboriously
    achieved final finish. 

    Its also a time saver, dunk the piece and go work on something else
    while it cleans. 

    Need to demount a glued pearl? Zap it in a sealed container with
    acetone, in the ultrasonic. 

    Leverage gauge sticky? same trick but with mineral spirits.

    BUT. They cost money. Even a small one is a few hundred bucks. Make
    the investment when you can't do without it.
