Okay, I realize this might be a loaded question, but here's my problem.
I've received some quotes of diamonds which seem low on AGS scale (3A, etc.) but rate very high on HCA (.9). Then I've seen diamonds which rate AGS triple ideal (including hearts and arrows) but low (3.7) on HCA.
I am doing this all online, so seeing the diamonds isn't an option (of course I can return, but would like to get it right the first time and won't have anything to compare it to anyway).
So my question, what the heck should I do? Should I go with AGS triple ideal? Or look for non-AGS ideal values that rate well on HCA? What is more reliable/accurate -- AGS or HCA? The jeweler I am dealing says HCA is not industry standard, and presumably he's right. But is it better, worse, or just different? Which is more accurate and reliable? I want a spectacular ring, obviously, with maximum sparkle, etc.
Thoughts?
