I am trying to verify am EGI International certificate. The online website says that this certificate does not exist. I have tried to contact them directly but no response. Does anyone know how else I can authenticate the certificate? The cert. number is 2311828530, 1.52 ct ,radiant, SI1, E color stone. I am dealing with a jeweler that I have known for years and don't want to believe that this is a fake certificate. I would appreciate any help tha ypu can give me. I dont want to go back to the jeweler until I know for sure about the certificate. Thanks
