Hi -
It has been said on this board (poster Gypsy's advice) to use HCA as a rejection tool and then use ideal scope as a selection tool. Or, alternatively, skip all of that and find an AGS 0 stone.
I have been following this advice in my shopping process, and only recently started encountering AGS graded stones - and some of them end up with AGS 000 gradings, but have specs that result in the HCA giving a rating above 2.0, even as high as 3.9. If AGS rates light performance at 0, but the HCA tool gives a 3.9 rating – does AGS win? I’m not sure how to treat these stones, so for the time being, I have to reject them.
Thanks!
