When buying jadeite, hetian jade and diamonds, can the merchant provide an appraisal certificate to explain the problem? In the interview, a senior jewelry appraiser bluntly said that the certificate issued by the authoritative national appraisal agency can prove the authenticity of jewelry, but it should be noted that there are many illegal appraisal certificates mixed in the jewelry market.

Fake goods are accompanied by fake certificates, and merchants make fake certificates in private.

The reporter visited a number of jade and Hetian jade merchants. Take jadeite as an example. When testing jadeite commodities, certificates of jadeite A and jadeite (treatment) can be issued. There are also many varieties of jadeite (processed), and the word (processed) is generally indicated on the national appraisal certificate. Take hetian jade as an example. Although there are many kinds of Hetian jade at present, there is no detailed classification in institutional testing. As long as it meets the composition standard of Hetian jade, generally only one certificate is issued.

"Authoritative certificate is the only criterion to identify jade." Liao, a member of the Jade Association and a senior jade jewelry wholesaler, admitted frankly that some informal businesses did confuse the whole industry market with false certificates.

According to industry sources, consumers are most likely to be planted on some "decent" false certificates. These fake certificates will be printed with the words "XXX Jewelry Product Inspection Station" and "XX Jewelry Inspection Center", and the red seal of the appraisal institution, the signature of the inspector, the sample photo, the inspection number and barcode, and the relevant standards for supervision and implementation will be specially marked on the back. According to the merchant, this certificate can only be identified by online inquiry or telephone inquiry. Fake goods with real certificates "civet cats for princes"

The case appraisal, only through the appraisal, the appraisal certificate issued is valid. One of CMA, CAL and cncal is valid on the jewelry and jade appraisal certificate issued by it, especially the first mark CMA, which is the certification mark required by the state. CMA is a metrological certification and evaluation institution composed of countries or provinces. CAL is the symbol of testing and inspection institutions recognized by AQSIQ. CNACL is a symbol of national laboratory, which is recognized internationally.

Second, look at the content of the exam. Including the name, color, purity, total mass, density, refractive index and other items of jewelry, these items are very strict in the nationally certified jewelry and jade testing institutions.

Third, look at the signature of the appraiser. The appraisal certificate must be signed by two appraisers before it is valid. One is an appraiser and the other is an auditor. Fake goods with real certificates "civet cats for princes"

In addition to some merchants sticking fake certificates on jadeite (processed) products, in recent years, some merchants have also thought of a better method of counterfeiting, that is, after jadeite (A goods) issued the certificate of an authoritative testing organization, they adopted the way of "exchanging civet cats for princes" and sold fakes with real certificates.

Consumer Ms. Chen spent 5000 yuan to buy a jade pendant with beautiful color and good water head. The owner of the jade said it was absolutely pure natural jade (product A), and attached the appraisal certificate of the authoritative organization with the pendant. The test photos on the certificate seem to be the same as the jade pendant purchased by Ms. Chen. "The photo on the certificate can only be said to be 90% similar to my pendant, because I can't see it clearly, so I'm not sure." Ms. Chen took the jade to the city gold jewelry testing center for re-inspection, and the test result was jade (processing). So, where is the problem? After consulting the certificate provided by the merchant, the staff of the testing center informed that the certificate provided by the merchant was true, but the jade pendant sold to Ms. Chen had been "replaced".

Don't believe the authenticity of jade. Look for the national professional jade appraisal institution.

Distinguish the authenticity of the appraisal certificate mainly depends on the following aspects:

First look at the inspection agency. The state has strict information on the quality appraisal institutions of jewelry and jade.

Fourth, the seal should be stamped and the font should be legible.

5. There is a serial number on the back of the appraisal certificate, which should be consistent with the serial number posted on the back of the physical object.

6. The certificate can be queried online or by SMS.

It is worth reminding consumers that the nationally recognized jade appraisal institutions are very strict in testing and can rule out the possibility of issuing false certificates. If consumers encounter problems with the certificates issued by authoritative appraisal institutions, they can complain to the Municipal Consumer Protection Committee or the industrial and commercial department. Once it is confirmed that a nationally recognized testing institution has issued a false certificate, it can be investigated for legal responsibility.
