Thanks again. I originally thought that I wanted ideal cut, ideal polish, ideal symm, etc etc. etc. The stone I am looking at is 1.51, ideal id/id, h vs2. I just found a 1.51 ideal id/VG, h vs2 for approx 700$ less. I figure I am spending about $11K, I might as well spend the extra to have the very very best. Can some one out there tell me it doesn''t matter (yet again)
