Where is the GIA inscription located on princess cuts?

[bp]

I have a princess cut diamond which has a GIA inscription on it and was wondering where it''s located. Also, is a microscope the only way to view it?

It should be on the girdle. Inscriptions can sometimes be seen with a 10x loupe but oftentimes you need a stronger loupe or a microscope.

I have a princess, it is on the girdle more to the right. I can see it with my 10x in good light.
It is real real small!!!
