My ering was purchased 6 years ago and has one .50c round center stone, 3 channel set princess cut on each side, but also has channel set round diamonds on the outside of the band. I have not seen another ring like it and wondering if thats a bad sign. I havn''t lost any stones yet(knock on wood), but wonder if this should be a concern. Does anyone know what kind of setting Im talking about?????? just curious
