I bought my gf a 1.65 round diamond, her finger size is a 4. I have it set in a Platinum 2.5mm Comfort-Fit Solitaire Setting. My question is is that a good size width, is it too small, shoudl I have gone to a 3mm. Not sure, it looks thin but again I am new to this, my jeweler says 2.5 is teh right choice....any suggestions???
Thanks.
Thanks.
