Hello, the certificate number of each piece of jewelry is not uniform. There are many authentication institutions, and the certificates issued are different, so the certificate number you mentioned is meaningless. Secondly, even if it can be found out, the value of this jewelry is unknown. It only has content, weight and composition, which means it can judge the authenticity of jewelry, but it can't confirm the price. I hope I can help you, and I hope to adopt it! !
