How to send a short message to the gem identification center?

Due to the confusion of short messages, most testing institutions do not support short message query at present.

Pay attention to when checking the certificate:

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 of them can be listed companies in Dongguan, and some can be street shops in Beijing.

2, jewelry testing institutions must have several signs to reflect the authority, they are indispensable:

CMA measurement certification mark is an access mark, and if it is not, it is illegal. Some people claim that it is state-owned, and it is nothing more than a registered institution or 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 is also 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 speaking, it depends on the website construction of the unit. If an organization's website is not very rich in content, not updated in time, or even not opened at all, but it is only established to check the certificate, then 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 in different testing units, and the fees are also different. However, if the detection 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 they can also save the certificate fee. At this time, the risk of consumers is very great.
