The qualifications of this institution are as follows:

China Business Federation Jewelry Quality Supervision and Testing Center is the only jewelry and jade jewelry quality supervision and testing unit approved by China Business Federation (former Ministry of Commerce) in the field of commercial circulation. The center's jewelry testing laboratory is a third-party testing institution that has passed the metrological certification of Beijing Municipal Bureau of Quality and Technical Supervision and the national accreditation committee for conformity assessment in China.

It can be said that the jade jewelry tested by this mechanism is enough to be worn with complete confidence.

I hope the answer can help you.
