As soon as you see the certificate, search the name of the testing organization online to see if there is any negative news on the internet, because such negative news may lead to distrust of the quality and price of the product itself. Check the certificate to pay attention to:

1, the so-called national jewelry testing agency is a kind of propaganda language, without any affiliation, just like the place where the company is registered, some can be listed companies in Dongguan, and some can be street shops in Beijing.

2, jewelry testing institutions have several signs of authority, which are indispensable:

CMA measurement certification mark is an access mark, and it is illegal not to access it. Some people advocate that it is national, but in fact it is nothing more than a registered institution, the State Bureau of Quality and Technical Supervision. In fact, this is the most basic condition for testing institutions.

CNAS: Similar to ISO, it is a voluntary behavior of enterprises, and qualified enterprises can apply for and obtain it. Because it is a standardized rule of international organizations, it has also been promoted to international mutual recognition.

CAL: Government behavior, a market supervision and management function that can only be owned by the government.

3. The above qualifications are either obtained or must be authoritative. Whether the company has the ability to engage in related work has a great relationship with the management level of the organization. This mainly depends on the personnel, equipment and establishment time of the unit. Intuitively, it depends on the website construction of the unit. If a company's website is not very rich in content, updated in time, and the number of visits is low or even not opened at all, it is only established for verification, so its investment in other aspects can be imagined and saved.

Smart consumers should know whether their certificates are authoritative when buying goods, because the prices of certificates vary greatly from several yuan to at least several hundred yuan for different testing units, and the fees are different. But if the test is wrong, the goods will be 100% in the hands of consumers. Especially online shopping, the trust is very low, and the certificate is very important.

5. If merchants choose certificates with incomplete certificates (CMA, CNAS, CAL), it shows that their strength is average, and the cost of certificates can also be saved. At this time, the risk of consumers is very great.
