I've been digging into 'diamondology' for a while and what I have noticed is that different gem labs have different credibility. I found a topic at this forum from 2002 about low quality of IGI reports. Has something changed in recent years in you opinion? The same goes to HRD which I heard is the best grading laboratory in the world, but some say it is not. On the other hand GIA reports seem to cover less information as to the cut quality (e.g. they do not grade H&A). I want to buy a stone with IGI cert as the most 'common' here where I live. What are your thought about this?
