Im having a major problem with my rings-especially my wedding set. The engagement ring slides inside of the wedding band, so its 3 layers thick..which is fine but for the last month or two on many days the whole thing is literally falling off my hand! I cant get it re-sized because with my kidney problem some days it feels tight already....does anyone know of a temporary sizer I could take off and on? Im getting afraid to even wear it for fear of losing it...
