I am working on an eternity band and had settled on .30 carat stones prong set in boxes. I originally wanted a band that was wide--5 to 7mm for finger coverage as much as anything--but also to show off the shape of the boxes--octagonal or hexagonal. I figured .3 carat stones (4.34 ish diameter) plus a couple mm''s for the metal and that was get me to about 6. However , I also want the band shallow and low to the finger. I am wondering at what point the up and down thickness will make it uncomfortable between the fingers even though it wont be prong set. Any comments or insights are appreciated?
