I have been reading everything I can about the crown/pavilion angle tolerances in addition to how to understand the rest of the numbers and I wanted to get some opinion from the forums on the stats for this diamond.

Here are the AGS values
The diamond itself is a 1ct AGS 000 ideal cut diamond.
Table %: 56.6
Depth %: 61.5
Crown %: 15.0
Crown Angle: 34.9 --> Sarin says 34.6-35.3
Star %: 54.0
Pav Angle: 40.9 --> Sarin says 40.6-41.0
Pavillion %: 43.1
Lower Girdle %: 76.0
Girdle Min-Max %: 1.5-3.7

from reading everything I think the Pav angle is okay, but is the crown angle tolerance of 0.7 something to be concerned about?

All the images look good. Wider ranges simply suggest it's more likely for the stone to have symmetry issues. But since it's an AGS0 and the IS/ASET checks out, I don't see much to be concerned about. Don't put as much weight on the computer generated map when you have actual IS/ASET images.

Okay thanks...guess I was starting to over think all the values/stats of the diamond on the associated Sarin and AGSL generated map.

There are too many variables in cutting to make a decision based on Sarin data. If AGSL says the stone is a top end stone, then in all liklihood, it will be a lovely looking diamond. The numbers you provided look completely acceptable. The nuance differences in ASET or I-S images cannot really determine what you might choose when you examine a few diamonds in identical lighting, side-by-side. Personal preference cannot be predicted to that degree.

Thanks for all the responses. I think I was getting a bit paranoid looking at all the images, numbers etc. because I am picking this stone as a surprise e-ring and really wanted to find the best stone within my budget. Like the poster said above though, as good as it looks through all the online images provided, I won't really know if I like it till I see it. Either way I have already made the move to purchase this stone.

Congrats :))

Just as oldminer says. The scan really should list machine uncertainty - it does not, which is misleading.
