PGS?

[JB71]

Has anybody heard of Professional Gem Sciences? They are a independent lab for grading diamonds. They have offices in Chicago and LA
If anyone has delt with them, how to they compare to the other well known companies? I am seeing a lot more stones with their certificates lately.
Thanks

Very reliable lab with good ethical standards.

They probably could give you the angles of any stones they graded because they run a Sarin report on each stone.

Good people, great lab. No problems and reliable. I am doing everything I can to duplicate their excellent reputation in my area. I have never seen a report from PGS that I found inaccurate. That is a high standard to meet.

Thanks for the reply

They are the ones who certified the 2.07 old european cut diamond I just purchased. At least I know the report is accutate. Thanks again for all of your input.

You were asking about enhancements?
Call them and ask about the fracture filling.
