I am looking at a Royal Asscher diamond and it looks pretty good. But I noticed that the GIA report date is 2001. I believe it is a new (unused) diamond so does it matter? I know that the availability of these types of stones are more limited, but will it give me any room to negotiate on the price (which would be great!)? Will there be the same type of markup as a more recently dated GIA stone? Thanks in advance.
