Hello! Can I get some opinions on the specs of this stone? Given its GIA XXX rating and considering it's angles and proportions, do you think it will perform well?

Thank you.

GIA XXX RB Specs:
Total depth.........62.0%
Table size...........57%
Crown angle........36.0 deg.
Crown height.......15.5%
Pavilion angle......40.8 deg.
Pavilion depth .....43.0%
Star length..........50%
Lower half...........80%
Girdle................Med. to slightly thick, faceted (3.5%)
Culet.................None
Polish................Excellent
Symmetry...........Excellent
Fluorescence.......None
 
Crown angle........36.0 deg.

You are going to see some of the pro's chime in on this. Ideal range is 34-35, but they will know best if this will affect the performance
 
I put the specs in David Atlas' cut class grading tool and received a 1A on everything but the crown angle - which scored 2B - which made the total score a 1B which seems like a pretty good grade any way. Going to try the HCA tool next...
 
Bump...
 
Numbers could work depending on the rounding by GIA. Needs an idealscope image to verify.
