Most professional, certified jewelers would not downsize a ring of this quality because it degrades the integrity of the outer coating of pure silver. Can it be done, yes. But it will decrease the value of the ring. An alternative is to have the bottom of the band layered with silver (to tighten the fit) and then recoat the ring. But again, your ring will lose value as any trained professional will be able to tell. Again, most reputable, certified jewelers will not do it.
