I will be getting a solitaire for ering and an eternity band, and my finger size is between 4 and 4.5. The sales lady recommend 4.5 for the eternity band because it''s hard to resize later and 4.5 is safer in case my weight changes. How aobut the ering? i don''t want the diamond to be twisting around so tighter might be better, so when you guys chosen your rings did you go with bigger size or smaller? thanks
