by kateek » Apr 15, 2002 Experts, please weigh-in on this one: I have a platinum engagement ring that is currently size 7.5. I need it re-sized to 5.75 or 6.0. One jeweler said I should have the ring re-cast to the proper size and the stones remounted (he claims the re-size would loosen the side stone mounts). Others have said to simply go witha re-size. Still another said to use "ball" sizers. Your expert opinions are appreciated. Thank you!
