HRD also has H&A grading.
It seems like they don''t like shallow combos.
If I understand everything, HRD doesn''t like longer lower halves, especially in diamonds with a deep pavilion.
I think they are missing a lot of beautiful combinations.

yea they are.
There is a discussion around here somewhere about it.
Its about a pretty heart picture not performance.
That is the biggest problem with h&a sometimes the highest performance and best looking diamond is at the ends or over the end of the h&a pretty heart picture spectrum with some c/p angle combinations.
