Hi all,
I wonder if graining is something mentioned on HRD and IGI certificates?
Thank you!

* minor graining

Hello Robbe,
I have seen your old answer, and probably you could also answer to my question, that is:
"graining is present" in the comments side of a IGI certificate, can change the price of a D IF triple excellent 1,56 carat ?
I should buy this diamond and I am wondering if I must ask for a double discount (based on rapaport prices) or if I should not consider this statement to try to lower the price.
Thank you very much
Regards
Mario
