A GIA lab report can take a few days to a couple of weeks. The time varies as the Fall season approaches and things get busier.
Some sellers will give you a report and others will make you pay for it. A lot depends if their profit margin is large enough to support the added expense. Also, a seller who knows the grading you have been told is incorrect will not want to give you a report that will kill the sale when the truth becomes known....
The GIA paper is a good thing to have when shopping for a diamond. If you love a diamond without a paper, find an appraiser to check it out. You will save money and it will make short work of the process.
Of course, if you need a GIA report in order to decide, insist on it.
BTW, I think you can call them and make an appointment, if the lab is near you... You leave them the stone, go shopping for an hour of two, and return to the lab and take the stone already graded. I'm not too sure about this, but several persons told this. You can give them a call.

It used to be that the stone had to be a minimum of 3 carats to be able to get this same day local service, Giangi. I haven't checked recently to see if that policy has changed or not.
