Engagement marriage season has come, the market followed the booming sales of jewelry up. Recently, several members of the public reached the party newspaper hotline "88869996" questions: buy jewelry in many styles often encountered in the identification certificate, then how to distinguish between these certificates? Certificate of those have national and local level it? "Foreign certificate" is not more reliable? Certificate "squandering" the phenomenon of a charming eye: the people Mr. Wang intended to "51" during the engagement, he was a long-established urban jewelry store buying a pair of small diamond on the ring. This diamond ring is selected, the shop owner out of the 4 drawer jewelry certificate of authenticity asked: "We are here 'Guo Zihao' certificate, the certificate of Wenzhou have, what do you want? "Boss also laughed and said:" You have to Guozi Hao's also a state-level results of the inspection agency more authority. "Mr. Wang a look and feel strange: its a ring and how it has two identification certificate, the certificate also has national and local levels of the points? Phenomenon 2: Last year, the public Xiao Yang delegation to South Africa with some friends to travel. A local jewelry market, Xiao Yang has its eyes on a diamond ring, clarity grade for the VVS, total weight is 2.25 grams, price is equivalent to more than 7000 yuan. At that time, the jeweler has come up with a world-class identification certificate issued by accreditation bodies. Xiao Yang felt that the certificate is out of the international authoritative institutions, the price of similar products cheaper than national more than 1,000 yuan. So he bought back. Thawed, Xiao Yang While this diamond ring to get a local identification of bodies have been identified, the results of its clarity but for the VS level, that is one level lower. This time, Xiao Yang only eat boring loss of copies of the. Certificate where no national distinction for the public face of the confusion Wang, Detection of hospital quality and technical supervision and inspection station stone jewelry, said Xu-Guang Wang, Senior Engineer, usually, the physical identification of the certificate and identification is one to one relationship, that is a diamond ring corresponds to a certificate; In addition, the certificate has not divided into national and local levels, and no more authoritative level of distinction. Agencies on how to distinguish between the problems identified, Xu-Guang Wang introduced, consumers may be noted that there will be a general diamond certificate of authenticity CMA, CNAS, CAL English flag. CMA refers to the national measurement accreditation, with this sign shows this third-party testing organizations engaged in the external qualification. CNAS means the Chinese National Laboratory Accreditation, the logo shows the detection of stronger institutions, the test results good authority. CAL refers to authorize the certification of Quality Supervision, the logo shows that there is quality supervision institution of the market authorization status checks. Xu-Guang Wang introduced, as long as CMA logo, regardless of the name of your unit marked "State" or "some provinces and cities", can be identified as a third party engaged in the external services, its level is not divided, "National & rdquo ; and the "local level." In addition, CNAS and CAL logo, not the identification of institutions necessary for the identification, such identification with only the strength of these bodies may be more certain. Can not blindly believe that "foreign certificate" "'foreign certificate' is an international certificate, are authoritative. "Some businesses will be so stated. "Foreign certificate" really well? Xu-Guang Wang introduced the last two years from the actual situation, "foreign certificate" identification standard seems to be increasingly relaxed the signs, so that domestic Chuxian the Yi Xie, "Yang certificate" annotation level than the actual problem of high such as the net degree of labeling VS VVS, color label I J-class level, while a level difference, the price difference of about 10%. He is also an example: Last year, the State Administration for Industry and organizations in the circulation of the National Jewelry detection of product quality sampling found that the use of foreign inspection certificates of quality diamond product sample was deemed to have failed a high proportion of the product not meet the actual quality level certificates are marked. This also shows that "foreign certificate" did not think the authority, because the accreditation body too much, the average consumer does not speak foreign languages is very difficult to identify them. The national accreditation body of certification, consumers can often be online searching for their true and false identification certificate.
