2. No organization can issue the certificate of origin, which is unrealistic. For example, gold alloy testing tells you that the purity of gold is the purpose, so how do you judge where the mine is? . Without this ability, the jade appraisal institution can not only give the place of origin, but also give the price judgment, which is impossible.
3. If you want to identify jadeite, you can go to the Jewelry and Jade Quality Inspection Center. Generally speaking, every provincial capital city will have a jewelry and jade quality supervision and testing center. The most authoritative institution of this kind is the National Jewelry and Jade Quality Supervision and Testing Center, because this institution was originally affiliated to the Jewelry and Jade Jewelry Management Center of the Ministry of Land and Resources.
4. There is a jade processing shop in Lianchi District, Baoding City, located at No.207, Ligao Haoyuan, Tianwei Middle Road, Lianchi South Street.
5. Identification of jadeite can go to the local jewelry and jade quality supervision and testing center, which is more authoritative. In addition, in some jade crystal wholesale distribution centers, such as Sihui, Donghai and other cities, there will also be gem testing institutions.
