Question of AGSL ligth performance map

[woodfishes]

Hi,

The AGSL ligth performance map as below:


Does the center green (less bright) zone affact a lot? I even find some ACA diamond has this issue.

I believe it's got to with the pavillion angle. If its more or less than 40.7 you'll get either red or green. I'm a bit of a noob so keep checking for better answers but 40.7 or 40.8 can be the difference and both are ACA worthy.

My major concern is does this green zone imply an obviously visible dark area when looking at the stone?

Hi,
I'm a bit of a noob myself, but from what I understand, you do not need to be concerned about it.
