According to Q/CLSS001-2007 corporate standards, we call the content of 99.99%of it. Wanzujin adopts the golden melting process, with a purity of 99.99%of the supreme gold products. Thousands of gold is pureer than Qianzujin. Wanzujin surpasses national jewelry standards. It guarantees 99.99%of the product color. It ensures the overall unity of the quality of gold jewelry. And because the purity of 24K theoretical is 100%, it cannot be achieved in actual life, so if you must use K to measure 10,000 enough gold, that person thinks that "less and infinitely close to" 24K.
24K, because the gold content of 10,000 pounds reaches 99.9%, and theoretically 100%gold can be called 24K gold, but in reality, it is impossible to have 100%gold. Therefore, China stipulates that the content reaches 99.6%( Gold containing 99.6%) can be called 24K gold. The gold content is not less than 999.9, which is called 10,000 -foot gold, which is the highest value named in market circulation in the market circulation. However, it is not among the national standards, and the mark is the printed, 999.9 gold, AU999.9, or G999.9. The mark of gold jewelry includes manufacturers' code, materials and purity, such as: X Gold 990, XAU990, X -foot gold, etc. Among them, letters X are the manufacturer code. When making jewelry with different materials or different purifications, materials and purity should be represented separately. When the jewelry cannot be printed due to too thin or too small, it should be attached to the logo containing the mark content.
