If someone says to buy a piece of gold jewelry with a gold content of up to 99.99%, there is theoretically such a possibility, but the greater possibility is that it is fooled. Yesterday, the annual meeting of the National Jewelry Standardization Technical Committee was held at the Shenzhen Gold Jewelry Concentration Base. The biggest achievement of this meeting was that from the perspective of consumers, to meet the needs of economic and social development, GB / T 18043 "Precious Metals" was revised and approved "Non-destructive testing method for jewelry content X-ray fluorescence spectrometry", this revised new national standard will be implemented after reporting to the relevant national authorities for approval. The direction of the deputy director of the National Standardization Management Committee revealed that at present, China's gold processing and annual sales volume are as high as hundreds of tons, forming a huge consumer market. Due to the high price of gold jewellery and the recent fluctuations in gold prices in the international market, the revision of the testing standards for precious metal content in jewellery is of great significance to manufacturers, testing institutions and consumers. The reporter learned that a piece of jewelry with a gold content of 99.95%, after only one molding process, its gold content dropped to about 99.93%, and the processing of gold jewelry generally has to go through more than 10 processes, so consumers should not believe the so-called thousand gold jewelry. The revision of GB / T 18043 will also have a far-reaching impact on Shenzhen, which is a leader in the national gold and jewelry industry. Wu Fenghua, chairman of Shenzhen's local jewelry brand TTF, believes that the new standard will guide companies to compare the purity of raw materials in the past to the creative design of products, that is, "cultural gold content." Ni Zewang, Secretary of the Luohu District Committee, and He Haitao, the head of the district, who made a special trip to the meeting, said that technical standards are the core elements of high-end industry and market competition, and an important means to promote technological progress and independent innovation. As the location of Shenzhen's gold jewelry gathering base, Luohu District Government will spare no effort to promote Shenzhen's jewelry industry from brand strategy to standardization strategy, and promote the transformation and upgrading of this traditional superior industry.
