by ladyluck » Mar 26, 2002 I was just noticing a dossier on the GIA's website which includes what is called a laser inscription registry number. It appears as if this number is inscribed on the girdle of the diamond itself. In my experience I have not seen many certs with this feature. Is the inscription something that needs to be requested when you submit the diamond to GIA for certification? I was just curious as this may be another way to identify your stone.
