I found a princess stone certified by EGL that describes the cut as "very good". Is the rating for cut a standard one, or do different certifiers (e.g., GIA, AGL) have different standards such that a "very good" cut by EGL would only be a "good" cut by GIA?
ok - thanks. I've heard that EGL certifies stones much more "aggressively" than GIA or AGL. Is this true? Am I better off buying a diamond with a GIA cert?
Aggressively Or less accurately?...As Oldminer (David Atlas) wrote a while ago, if other labs would be as strict as GIA, who will send them the diamonds for grading?The point is, GIA reports are considered as the strictest in the trade. As a result diamonds with GIA reports cost more on the market.However, you always have a chance that GIA grader made a mistake or EGL report is absolutely correct...That's why it's recommended checking the stone with independent appraiser/gemologist.
