Hi, we are in process of buying an Emerald diamond. We asked the seller to get this diamond GIA certified. My question for you experts is that how do I verify that the GIA certificate is for the stone I am buying in case the certificate number is not scribed on the diamond. Since the seller is not an accredited store and he requests cash, what are some of the ways he could screw me and what do I have to be cautious about??
Thanks
Thanks
