Help please on evaluating this AGS light performance

[meataxe]

Dear all,

Fantastic forum here, I've learned so much from you all!

I've managed to narrow down my decision to 3 diamonds, 2 GIA and 1 AGS. Fortunately the AGS has the light performance image.

Question 1
I'm a little bit concerned about the center of the image, the symmetry looks a bit wonky in the circle. Is this poor camera work or is the diamond defective?

Stats:
0.84ct
G
VS1
Table: 54.8%
Depth: 62.3%
Crown angle: 35
Pav angle: 40.8
Star length (AGS): 50
LG: 77
Girdle: Thin-med 3%
AGS 000
HCA: 1.7, Ex/Ex/Ex/VG on brilliance, fire, scintillation, spread

Question 2
Are the following Star/LG ratios acceptable?
1. 55/75 (GIA) - other stats are table 55/ depth 61.8/ CA 34.5/ PA 40.8
2. 50/80 (GIA) - 55 / 61.8 / 35 / 40.8

Many thanks in advance

Looks great, image wierdness is the image. AGS0 = no real thinking required It is the most strict lab for cut quality grading around.

If you WANT to think about it, then you need real life photos or to see it in person, and you can use an idealscope to confirm the ASET from the report.
