Hi-
I am a scientist (brain not gems), so I am a data person. Now my head is spinning a bit because of all of the cut grading systems. I am getting disparate answers from HCA, AGA, and AGS on a specific stone. I am getting close to buying so please help.
2.84 H VS1
9.01*9.07*5.68 mm
Depth 62.8 %
Table 56.7%
Crown: 35.5 degrees 15.3%
Pavil: 41.3 degrees 43.6%
Culet: 0.8%
Girdle medium to sl. thick
VG/VG
By AGS this is essentially 1 on Pavilion depth, 0 for crown angle, 0 for table, 0 on girdle thickness, 0 on culet ..... so pretty good
By AGA Atlas'' system puts this at 2A (table 1A, crown angle 2A, Crown height 1A, pavillion 2A, girdle 1B, depth 1B..... pretty good
But by HCA this is one of the worst stones I have checked at 4.4 (only if price is the main concern)...
Please help what gives? I guess I am starting to split hairs maybe..... Or am I seeing further down the rabbit hole
?
Thanks for any input on this stone.
