My husband and I just recently purchased a new stone and setting from James Allen. But now I am second guessing the table and depth. I want the spread to look good and want the most bang for my buck. Did we make a mistake based on gia report? Our budget was 11000 for setting and stone, I need platinum because I develop an allergy to the alloys in gold after time. We spent 8450 on the diamond. we also wanted to get setting and stone from same place to make things easier. I'm wondering if there are better choices out there
