Ask an expert to explain. What if I can't find the number on the diamond certificate? Besides, ask someone for advice. Am I being cheated?
You can check it again carefully, because the number is based on the certificate, so let's see which certificate it is, and then check it again, just like GIA will say next to it, just enter the number, so check it carefully, if it is a loose diamond, see if there is the same number at the waist. Actually, what I want to say is that the diamonds you bought should be real.
