Looking at several diamonds, I noticed that the AGS Ideal light rated diamonds are often scoring fairly poor on the HCA scale. Is the HCA just an estimate? One I looked at had a 2.8 score, another a 3.7. Does that mean the AGS Ideal light performance rating is weaker than the HCA elimination tool? Or that the HCA is just an estimate, a good way to weed out poor performers, but also a tool that lets strong performers get eliminated unnecessarily?
Of course, there are still plenty of AGS ideal diamonds that score under a 2, but being the AGS ideal rating is fairly strict, I would have guessed it was pretty much 100% scoring at or under 2. Please explain, it is a bit confusing!
