    I note that many here are saying the ring can be sized w/o removing
    stone. Maybe, maybe not. Depends on the ring itself and how much of a
    change is required. If there is a drastic change, the base shape of
    the ring will certainly change, pulling prongs away from stone if the
    ring is made smaller, or squashing the stone if its made bigger,
    possibly requiring new prongs altogether. And maybe distortion or
    damage of the filagree. Have your jeweler look very closely at the
    join of shank to top, a frequent troublespot. 

    On any old ring its important to scrutinize the piece for previous
    repairs. Sometimes they are difficult to see if they were done well.
    If there is white gold solder that was rhodiumed, the jeweler might
    have a real surprise if he tries to platinum weld new tips or prongs. 


    Retipping as I've seen it, is done with stone in place so that's out
    in the case of peridot. Tipping with stone out is not very good imho,
    a short extension that bears the force of bending over the stone.
    Solder does not like to bend. Better to replace prongs entirely as a
    matter of course, if, and its a big if with antiques, the mounting
    can handle the repair.
