HCA1.3 but GIA cut "Good"

[SnakeEyes111]

I was doing a PS search of diamonds and came across the following GIA rated diamond from James Allen (http://www.jamesallen.com/diamond.asp?cid=131&item=860640). HCA rates it a terrific 1.3 but GIA''s cut rating is only "Good." What''s going on here?

its a shallow/shallow diamond.
ie: shallow crown / shallow pavilion
HCA passes some of them GIA knocks them down.
For a ring I agree with GIA for a pendant or earring I agree with the hca/Garry.

edit: ran it thru diamcalc: its about an AGS 5

Thx Storm.
Read the explanation about the position of the X on the chart at the link below the HCA result here http://diamonds.pricescope.com/ideal.asp

The stone is SI2 - check out if you are happy with that - if you can see SI2 inclusions you may not like the cut either.
