At present, there are several companies (including Zhaomou Yinlou, Seymour, Lanmou Wanjin, Jinmou Wanjin and Zhongmou Wanjin) that produce high-purity gold with 99.99% gold bars, which is euphemistically called Wanjin. Of course, this kind of gold is indeed purer than Wanjin and Qianjin, but the converted price is only within 3.5 yuan. That is to say, the difference between "pure gold" and "thousands of gold" is only 3.5 yuan per gram, and the difference between thousands of gold and thousands of gold is only 3.5 yuan per gram. In fact, 99% of the gold is pure, and the new national standard GB 1 1887-2008 further improves the purity of gold jewelry. This time, however, jewelers made consumers pay more money at the expense of raising the new national standard. In fact, it only improves the fineness of 3.5 yuan per gram (because the raw material price of gold 9999 is within 350 yuan), and the cost of Wanjinjin only increases that of 7 yuan, because there are only two differences in fineness, each of which is different from that of 3.5 yuan per gram. If a piece of pure gold jewelry is less than 7 yuan per gram, it will be more cost-effective. If it is tens of dollars higher, it will be uneconomical. Several major domestic gold jewelry manufacturers are OEM for other brands, including Baitai, Hao Yue, Jinlong (Mingfeng), Longjia and Xinjin. Here we should focus on our Hubei brand gold, which has always been famous for its best quality, most stable quality and excellent workmanship. August 10 was listed in the United States. However, in the tide of market economy, gold does not pay attention to brand building, and has long served as a substitute for other big brands, such as old tricks. As a result, brand development is now stagnant. Now I have switched to other industries. Of course, gold jewelry is still being produced.
