The National Committee of Jewelry Standards and Technology passed the mandatory revision of the Law on Purity and Naming of Precious Metals in Jewelry, stipulating that jewelry products with sufficient content (gold, platinum, palladium and silver) have the highest purity. This standard was formally implemented on May 4, 20 16. It was cancelled after entering the international stage 14 years.

Why do you want to cancel the statement of "thousands of dollars"? Why is it difficult to stipulate that all gold is the highest purity of gold jewelry?

In this regard, the National Standardization Administration Committee explained that the gold content of jewelry is not less than 999‰, and the gold content of jewelry is not less than 990‰.

Gold ornaments, mainly used for decoration. However, gold ornaments with high gold content also have some shortcomings, such as low hardness and easy deformation. In order to ensure that the gold content meets the requirements, solder cannot be used in the production process, and the modeling style of gold jewelry is limited. There is no difference between products with 990‰ content and products with high appearance content. Solder can be used in production, which can make the shapes and styles of gold ornaments more diversified and have more choices. The cancellation of "Qianjin" statement does not mean the lowering of industry standards. The formulation of standards is more in line with the characteristics of gold jewelry products, and also reflects the responsibility of protecting consumers' rights and interests and promoting market fairness.

In particular, the raw materials of 65,438+0,000 pieces of gold ornaments generally adopt the national standard 1, and the gold content is 999.9‰, which is only 0.9‰ higher than that of gold.

Take 10g gold bracelet as an example. The raw material is 999.9‰ GB 1 gold, and the impurity content shall not exceed 0.009g

The highest gold color of solder is only 98%. The more solder joints and flux, the lower the gold purity of jewelry.
