The GIA measures the crown and pavilion angles for every diamond that is submitted to them for grading, however they consider the information to be "proprietory" and they will not release it to anybody but the person or company who submitted the stone... This is NOT necessarily who owns the stone! Perhaps they do this to avoid legal complications with the cutters who submit diamonds to them because those people might be upset to lose a sale three years down the road to a client who just learned that the diamond they purchased isn't all that and a bag of chips...
Although it would be nice to get the SARIN info from GIA, the fact that they do not release it should not be of any concern to you as you involve yourself in the diamond buying process. An increasing number of educated consumers are asking for SARIN reports as CUT becomes more important. Be sure to ask for this information from the company you are buying your diamond from. In most cases, a reputable company will be able to supply the numbers for you.
Gosh everybody makes it sound so *impossible*...if you really want the info, open an account with the GIA and shell out the bucks (around $100 or so for the average stone) to get the report updated, and maybe an inscription while it's there. Problem solved.
Edited to add, if it's not obvious: you only get to do this after the stone is *yours*
Agreed, Giangi, just wanted to point out that if someone specifically wanted the GIA numbers they could simply ante up and pay for them. It is interesting to me when I see 3rd party Sarin reports where the %s and measurements are different from the GIA report by a significant amount. The closer the diameter, depth, and table are to the actual report, the more confidence I have that the angles are close to what the GIA saw.
BTW the update fee is only 75% of the original report fee.
