Hi, Mlh!
GCAL doesn't use the AGS ASET, but their scope does reveal quite a bit, as well.
This diamond likely has some pavilion painting, around 6°?
Very hard to try and translate the GCAL scope to ASET scope.

no it doesn't look at the leakage pattern.
Then look at the lack of black in the 6 degree pavilion painting aset.
With the gcal images you have to look at both the leakage image(optical brilliance) and the symmetry image.

@Mlh - this was before we reported a few additional measurements
LGF is 76.57%
Star is 48.72%
There is crown painting of 1.75 (average)
@DejaWiz was correct that there is pavilion painting of 0.57 (average) and a max of 1.34
and below is the slide we showed during the webinar of the painting and digging we allow on 8X

finally, just for reference, because we hadnt taken hearts and arrows images for this stone, this is the ray-traced generated image of the hearts of GCAL Cert 300380065
to be clear - if we show hearts and arrows on our cert or web page, it is always actual
but this is the ray trace from the scan (in lieu of the actual)
