“Thousands of gold is the national inspection standard, and Wanjujin is the registered trademark of the companyâ€
According to the national standard GB11887 "Purchase precious metal purity regulations and naming methods" clearly stated: "24K theoretical purity is 100%". In other words, "24K" goods do not exist in actual life, just a theoretical value. According to the definition of national standard, gold is divided into the following types, and the minimum values ​​of purity and fraction are expressed as 375, 585, 750, 916, 990, and 999, respectively. Other representations of the corresponding purity are: 9K, 14K, 18K, 22K, full gold, and thousands of gold. For jewelry, the national standard is only defined to thousands of gold. At present, the Chinese market is full of gold: "three nine gold", the color is 99.9%, commonly known as thousands of gold; "two nine gold", the color is 99%, commonly known as full gold. Therefore, according to the current national inspection standards, gold has only a thousand gold and gold standards.
There is no national standard at all. In fact, the reason for “full gold†is the trademark registered by a company for its own gold jewelry. The so-called gold jewelry with a gold content of 99.99% is not covered by the national standard. Name, in the gold consumer market in 2013, there are “wanting goldâ€, “Wanchunjinâ€, “wanting pure goldâ€, “Wanchun supremeâ€, “Wanchun real goldâ€, etc., which are different from those of Jinjin and Qianjinjin. Consumers, it is worth reminding that the country does not name Chinese products with a gold content of 99.99%. Therefore, the Chinese name “万*金†does not have legal effect.
