im looking to buy an e-ring by the end of jan and was wondering do i buy the setting before the diamond or the other way around? also i want the diamond to be 1.5ct round, H color, SI1 eyeclean, EX cut, NONE fluroscence, at the least and was wondering if its ok to get Very Good for the polish and symmetry? im trying to make all this work with a 15k budget but i need to stay at the 1.5ct weight and was wondering what my best choices were. considering she wants a cushion halo with melee, im not quite sure how im gonna make all this happen. i want to make her happy cause this ring is forever but at the same time i absolutely cannot afford a nickel more. i feel like im already stretching but i want to make this work cause she is my world. please any help will be greatly appreciated
