I have purchased this stone from since1910 but can still change it in the next few weeks if I really wanted to since the setting takes 4 weeks to get. Price is just over $4400 for the stone. I have been reading about the variations between the GIA and other grading systems and am worried that this "very good" GIA rated cut may not be as good as they are saying. Is the low crown height and angle something I should be concerned about? Am I overpaying? If it is still going to be a beautiful stone and I am not getting ripped off then Ill be happy. Thanks for your help!
