I won't name any names yet.
I purchased a 3.6 ct round diamond about 2 months ago from a sponsor of this site. It was sold as an AGS I SI1 ideal. We went to have the diamond set today and the jeweler who cast the ring says there is a GIA number on the girdle. A GIA number on an AGS stone? Sure enough, GIA 2171725278. He pulled the certificate. GIA grades it I, SI2. The AGS report is dated June 2016 and the GIA report July 2016. They differ slightly on the measurements but I'm pretty sure it's the same diamond. The weight is the same on both certs.
Is this common? Did I get scammed? The jeweler who set the stone was angry to see this. My guess is they had the AGS grading then went for GIA, but when GIA came back lower they sold it with the AGS certificate. But why get the inscription?
Do you think there's any chance the seller didn't know about the GIA inscription? And the big question, all other things being equal, would someone typically pay more for a GIA SI2 or an AGS SI1?
