الاحتياطات الواجب اتخاذها عند شراء خاتم ألماس مستعمل

Thank you for your quick response,

But let say if later on, he reported to the police that I stole the ring from him, do I need write a paper between me and him that I bought it from him and write the certificate number of the diamond and his ID number and mine as well?

Thanks in advance.
