So here is my CAD from ERD. Center diamond is 1.521 carats. Because I am pretty clueless, I'm just looking at what's aesthetically pleasing. It looks pretty good to me, with the exception of the pave diamonds on the shank. I think that they go down to far on the band (I think I initially told them to end the diamonds at about the 5 and 7 O'clock positions, but maybe I should suggest 4 and 8 instead?)
