There are many ways to identify jadeite, among which jadeite certificate is one of the simple and practical methods. To some extent, the certificate is like the identification of jadeite, and the unlicensed jadeite is like a "black household", which is not recognized.

But now the jade circle, even if there is a jade certificate, can't guarantee that the jade is true, because even the jade certificate is fake, so do you know what kinds of jade certificates there are? How should we identify their authenticity?

Jade certificate category:

Generally speaking, the common jadeite appraisal certificates can be divided into three types, namely, national inspection certificates, provincial inspection certificates and certificates issued by universities and third-party testing institutions.

The State Inspection is affiliated to the Jewelry and Jade Jewelry Management Center of the Ministry of Land and Resources. It is the maker of China's jewelry industry standards and the most authoritative testing institution, referred to as NGTC.

Provincial inspection refers to the jewelry and jade appraisal centers in various provinces. For example, Yunnan Jewelry and Jade Quality Supervision and Inspection Institute is a representative provincial inspection institution with jade detection ability and authority.

Universities and third-party testing institutions actually belong to universities that offer jewelry majors, or some private enterprises. Because the operation of these institutions will involve private reasons, the standards of jadeite detection certificates issued by these institutions will also be reduced in national or provincial inspections, but this does not hinder their authenticity and scientificity. At the same time, the inspection fees of these institutions are also cheaper than those of national and provincial inspections, and many businesses are willing to use such certificates.

Appraisal of jadeite appraisal certificate

1. The jadeite appraisal certificate issued by a formal authority must be marked with "CMA", "CAL" or "CNAL" to represent the qualification of the institution, in which "CMA" is necessary. If there is no sign or CMA, the proof is untrue;

2. Regular jadeite appraisal certificate, besides the fixed English logo, you can also see the picture of the sample, the certificate number and the steel seal of the testing institution.

3. In the certificate content of jadeite, we should pay attention to whether the shape and color of real jadeite are similar to the samples on the certificate.
