PLEASE HELP/GIA report

Post#1 @ 10-31-11 , 12:05 PM

How is this an excellent cut? I used the Hollaway Cut Advisor tool and it is a 3.6 which is very good. Would you buy this stone for $14,000 or is it over priced?
GIA

7.84-7.86X4.68mm
round brilliant

Carat weight: 1.72

I get 2.9 0r 3.6 HCA depending on whether I enter the angles or percentages.
Florescence makes stone appear like a H. No milkiness or cloudiness in sunlight. Glows blue 3-inches from a blacklight but not 24 inches away.

GIA EX EX EX's can possibly not be cut that great. Even though I don't believe in the HCA as the last stone that I saw that his grading scale gave a 2.6 was awesome in light performance, and his only gave it a very good cut. This one was an AGS ideal hearts and arrows cut. So as you can see, his system doesn't always work.
