1 thought on “Quality inspection and spot check of jewelry products”

  1. Zhang Jun and Dong Jing

    1. Supervision and random inspection is an important means to regulate the market

    national supervision and random inspection is an activity that the product quality supervision department of the State Council organizes relevant provincial quality and technical supervision departments and product quality inspection institutions to sample and inspect the products produced and sold according to relevant regulations, and publicize and handle the results of random inspection according to law. It is one of the main ways for the state to supervise and inspect the product quality

    as a special kind of valuable consumer goods, the quality of jewelry has always been the focus of consumers' attention. The means of supervision and spot check not only reflects the current development situation and overall development trend of China's jewelry market, but also reflects some problems that need to be solved. It plays an important role in supervising the product quality in the jewelry market, popularizing the national, industrial and local standards and relevant regulations of jewelry, and regulating the business activities of jewelry enterprises. Through many supervision and spot checks on jewelry, the jewelry market has been gradually improved, the market competition mechanism of survival of the fittest has been initially realized, and the fair and orderly jewelry market competition environment has been realized. The overall product quality of the jewelry industry has been greatly improved. However, there are still quality hidden dangers such as nonstandard name of jewelry and jade jewelry products, wrong name, inaccurate classification and grading of diamonds, and it also reflects that jewelry enterprises and some quality inspection institutions have problems such as lax product quality control, insufficient understanding of standards, and insufficient technical level

    2. Sampling inspection of industrial and commercial jewelry monitoring in 2009

    the national jewelry and jade quality supervision and inspection center inspected the jewelry commodities in the circulation field in 6 key cities (including Tianjin, Shenyang, Shanxi, Wuhan, Chongqing and Hangzhou) according to the provisions of the letter of authorization for sampling inspection of jewelry commodity quality monitoring in the circulation field of the State Administration for Industry and Commerce (2009) No. 007 of the State Administration for Industry and commerce

    a total of 41 enterprises were sampled for monitoring and sampling inspection, of which 21 were qualified, and the qualification rate of sampling enterprises was 51.2%

    a total of 2478 jewelry commodities were inspected, including 75 samples. There were 1948 pieces of diamonds (including naked diamonds and diamond jewelry), 400 pieces of colored gems (including pearls, aquamarine, topaz, synthetic cubic zirconia, dyed quartzite, glass, etc.), and 130 pieces of pure precious metal jewelry

    among the 75 samples sampled for inspection, 49 samples passed the inspection, accounting for 65.3% of the sampled samples; There were 26 unqualified samples, accounting for 34.7% of the sampled samples. The overall qualified rate of this monitoring is 98.95%, and the unqualified rate is 1.05%

    among the 75 samples sampled, including 60 diamond grading samples, 11 jewelry and jade identification samples, and 4 pure precious metal jewelry. Among the 60 diamond grading samples, 44 were qualified, accounting for 73.3% of the diamond quantity, and 16 were unqualified, accounting for 26.7% of the diamond quantity; Among the 11 jewelry and jade identification samples, 4 were qualified, accounting for 36.4% of the jewelry and jade quantity, and 7 were unqualified, accounting for 63.6% of the jewelry and jade quantity; Among the 4 pure precious metal ornaments, 1 is qualified, accounting for 25.0% of the pure precious metal quantity, and 3 are unqualified, accounting for 75.0% of the pure precious metal quantity

    in the process of testing, the unqualified diamond grading samples mainly show that the marked color level and cleanliness level are not in conformity with the national standards; the unqualified jewelry and jade identification samples mainly show the wrong name; the unqualified precious metal samples mainly show the lack of material name and manufacturer code marks

    3 comprehensive analysis

    the inspection results show that the overall quality of commodities in the domestic jewelry market is relatively good. Well known brand enterprises attach great importance to the quality of commodities and the image of enterprises. Most of the enterprises have orderly internal quality management and carefully selected third-party quality assurance institutions, so the quality of the commodities can be better controlled. However, some jewelry enterprises still have potential quality problems

    3.1 problems of commodities sold by jewelry enterprises

    (1) wrong naming of jewelry. For example, "topA stone" is marked as "crystal"

    (2) jewelry naming is not standardized. For example, "dyed quartzite" is marked as "Malay jade"

    (3) incomplete precious metal imprint. For example, for some samples sampled this time, the precious metal is missing the material name stamp and the manufacturer code stamp

    (4) the diamond grade is unqualified. For example, the color level "H" is marked as "g" and the clarity level "Si" is marked as "vs"

    3.2 problems of quality inspection institutions

    most domestic jewelry quality inspection institutions have orderly internal quality management, and the test results are scientific, fair and accurate. However, there are some problems in the certification of foreign testing institutions. Among the 60 graded samples of diamonds sampled this time, 16 were unqualified, of which 14 were equipped with foreign certificates, accounting for 87.5% of the unqualified diamonds

    main reasons and their impact on the market:

    first, foreign testing institutions are basically commercial laboratories, and their testing standards are constantly changing with the changes of the market. With the in-depth development of China's economy and the increasing international trade, the inspection certificates issued by foreign inspection institutions have poured into the domestic jewelry market with a large number of diamonds. These diamonds sold in China do not comply with the national testing standards, and the technical rules of many foreign testing institutions are uneven, which is very different from the national standards. The inspection certificates issued by these foreign inspection institutions for diamonds less than 1 carat sold in China are generally false. This is a great impact on the gradual improvement of the national diamond grading system in China

    secondly, such foreign certificates with false high color level or purity level are especially welcomed by some enterprises. Sales enterprises take "international certificate" as the selling point and promotion means of sales. Such diamonds with false high color level or purity level also mean higher sales price, thus seriously damaging the interests of consumers

    thirdly, foreign testing institutions take the advantage of virtual high-level "International Certificates" to win some enterprises to cooperate with them. This kind of unfair competition has seriously damaged the legitimate interests of enterprises strictly implementing national standards and domestic testing institutions

    to sum up, the large circulation of these foreign certificates sold in China but not complying with China's national standards in the Chinese market will seriously affect and damage the healthy and orderly development of China's jewelry market

    4. Several suggestions

    4.1 strengthen the supervision of enterprises by the government and industry associations

    (1) focus on publicizing laws and regulations such as Metrology Law, product quality law, standardization law and consumer rights protection law to enterprises, so that enterprises can operate according to law

    (2) organize the management and technical personnel of the enterprise to seriously study the relevant standards of jewelry and jade jewelry, urge the enterprise to continue to strengthen the professional training of employees and constantly improve the quality of employees, so that the enterprise can strengthen the control of product quality, accurately mark the product labels and marks or other quality certification documents, avoid the phenomenon of non-standard, missing standard, wrong standard or even false standard, and ensure that the accurate product quality marks can enter the market, So as to avoid unnecessary product quality risks and disputes, effectively protect the rights and interests of consumers, and ensure and maintain the stable and healthy development of the jewelry market

    (3) strengthen the management of jewelry enterprises, strengthen the quality awareness of enterprises through regular supervision and inspection and selection of excellent enterprises, and constantly promote enterprises to improve product quality

    4.2 standardize the market

    step up the formulation and improvement of the management regulations on the identification of jewelry products, and prevent enterprises from wantonly relaxing the commodity technical standards through relevant management regulations, so as to further standardize and purify the jewelry market

    4.3 improve the quality of domestic jewelry quality inspection institutions

    improve the technical level and professional ethics of domestic jewelry quality inspection institutions, and escort the healthy and orderly development of China's jewelry industry

    4.4 give play to the advantages of the government and industry associations to clean up and rectify the domestic testing certificate market

    (1) it is suggested that the competent government departments formulate corresponding laws and regulations, and strictly require that the jewelry sold in the domestic market must be equipped with the testing certificate in accordance with the Chinese national standards

    (2) it is suggested that the competent government departments should strengthen the supervision of the jewelry market, clean up and rectify the domestic testing certificate market through regular supervision and inspection. So as to protect the fundamental interests of consumers and ensure and maintain the stable and healthy development of the jewelry market

    (3) make use of various media means (TV, Internet, etc.) to widely publicize national standards and domestic excellent laboratories to consumers, instead of blindly superstitious about foreign laboratories and foreign certificates
