Thanks very much for the info. I am looking at a 2.75 Royal Asscher and although it does have the crown and words Royal Asscher inscibed on the girdle, along with a specific number, I wanted to make sure the GIA report was not supposed to say Royal Asscher. After a little more research I now know GIA does not certify a brand name. Thanks again.
I suppose the mention of the Girdle inscription is an ID, because some non-branded stones are labeled the same - these are basically ''emerald cuts'' with some more steps.
