Hi, Please help, need to make a decision fast. I''m deciding between a G 1.39 carat diamond or an I 1.52 carat diamond. I know that a 1.39 is very close in size to a 1.52 but there is a visible difference. The 1.39 is 7.24 diameter & the 1.52 is 7.50 diameter. Should I go down in color for the larger I stone or would that be a mistake? I know that color is a personal thing but has anyone had to make a decision such as this? Size or color? Help!
