GIA vs AGS cut grade...using the AGS cut system

[Dancing Fire]

what is the lowest AGS cut grade inside the GIA EX cut chart? would it be possible for GIA EX cuts to score AGS 2 cut?

EO is good then? With a 60%table a 41.6 degree pav angle and a 31.5 degree crown angle? Most if not all tell me this is a no go. But AGS/GIA is a EO.

Could work, in terms of light return, it is good but might suffer from fire performance due to the shallow crown.
