by Irishgrrrl » Dec 16, 2008 . . . I know eternity bands can''t be sized, but I''m wondering why that is? I can see how it would be very hard decrease the size, but what if you wanted to increase the size? If you''re not concerned about keeping the design going the whole way around the ring, couldn''t you have a jeweler kind of "insert" a plain piece of gold/platinum/whatever into the band to make it bigger? (Basically, you would be asking your jeweler to add a sizing bar into the ring, I guess.) Or would that not work for some reason?
