Hello, I am about to spend USD60k for a 2.8 F VS1 3Ex diamond online, sight unseen except for GIA report and the attached picture, which shows the slight crystal blemish on the table at the 10 o'clock position. That's the only aspect concerning me. Vital stats are table 58%, depth 60.9%, crown height 14.5%, crown angle 34.5, pavilion depth 43%, pavilion angle 40.6, girdle medium to slightly thick, 0 culet, 0 flourescence. It comes up 0.9 on Holloway Cut Adviser (3 Ex with Spread Very Good), and all grade 1A on the AGA/NAJA screening tool. I want maximum clarity and sparkle. Do you beleive this is worth buying? Money back guarantee if not satisfied. Views appreciated based upon the stats given, many thanks!
