Jade has always been the favorite of China people. Buying and wearing jade articles is something that many people in China like to do. Of course, it is precisely because of people's love for jade that there are many fake jade in the market, and the most direct way for people to identify the authenticity of jade is to look at the jade appraisal certificate. However, there are many kinds of jade appraisal certificates now, so everyone wants to ask if all jade appraisal certificates can be trusted.

For the question you asked, I want to tell you clearly here that not all jade appraisal certificates can be trusted. Some testing institutions in the market just hang a brand but don't have the testing qualification. It belongs to informal testing institutions, so the jade appraisal certificates issued by these informal testing institutions are not authoritative and have no credibility.

In China, NGTC and GIC are authoritative testing institutions. The full name of NGTC is National Jewelry and Jade Quality Supervision and Inspection Center, which is an appraisal institution authorized by the relevant state departments according to law, and is the authoritative institution for jewelry and jade testing in China. GIC is the earliest and largest professional institution for gem education and research in China Geo University. 1993, GIC set up a jewelry testing center to provide entrusted testing services for jewelry and jade to the whole society.

The jade appraisal certificate issued by the above two institutions is very authoritative, so when you buy jade, if you see that the merchant shows you the appraisal certificate issued by either of these two institutions, then you can rest assured that this appraisal certificate is credible.

Ok, that's all the jade appraisal certificates. Let's say so much. If you want to know more about jewelry, pay attention to the famous jade carving fish. There is a wealth of jewelry knowledge and massive jade carving products for everyone to read and appreciate.
