All rough diamonds certified by international authorities have a unique certificate and corresponding code, just like a person's ID card. The certificate has the American diamond code, 4C quality grade, and if it is a carat diamond, there is also a clarity sketch, just like the photo on the ID card, which can be searched in official website. If the certificate, the actual internal characteristics of the diamond and the online inquiry match, there is no problem with American diamonds.
