HI everyone!
IN a recent thread, Marty (adamasgem) has made disparaging remarks about GIA.
Although GIA did have a problem last year,involving bribery.
This was exposed, resulting in changes to procedures, as well as firings of some high level personnel.
My position is that the problem was extremely limited ( involved only a few extremely high dollar diamonds, and one company) and has been handled.
Furthermore, GIA''s grading and general business practices are accepted by all the major players here in the US. This is how I see it , as a wholesale dealer here in NYC.
Do others in the trade have a different experience?
Marty, in that previous thread, you made this statement
How many stones a year does AGS grade? How long did it take to compile a 200,000 stone sample?

Can you please show us this study?In the PS archives their are some interesting results as to the percentage of time GIA and AGS give a D color... On sample sizes exceeding 200,000 available graded stones, one is about three times as likely to get a D from GIA versus AGS. Now when it comes to secondary labs, we don''t have enough published data, but it appears you can guess how it will turn out....
