You can never go wrong following Gypsy's advice. Whiteflash ACA's are a great choice - AGS0 stones that you don't have to think much more about other than size/color/clarity - they will all (almost certainly) be stellar performers. Same concept with Brian Gavin Signature diamonds - he is also great to deal with. Another option is contacting Good Old Gold and giving them your budget and asking them to search for an ideal princess for you - they carry the Solesfera line of princess cuts in that size - they have a distinct look that you have to be a fan of, but are gorgeous. I have had great luck with GOG but there is some work involved, i.e., choosing, looking at videos/pics/ASETs etc. With the BGD signature or Whiteflash ACA you can make a quick and easy decision.
