Whether it is pure gold or not has nothing to do with the brand. It is necessary to judge whether it is pure gold by observing the imprint of metal material and content on jewelry. The symbol of pure gold is XAu990 and so on. If it is pure gold jewelry, it will also be marked with pure gold.

Thousands of gold with a gold content of not less than 999 is called thousands of gold, which is the highest value in jewelry color naming. The stamps are thousands of gold, 999 gold, 999 gold or g999 gold. The imprint of gold jewelry includes manufacturer's code, material and purity, such as X Gold 990, XAu990 and X Pure Gold. Where the letter X is the manufacturer's code. When jewelry is made of precious metals with different materials or purities, the materials and purities should be indicated separately. When jewelry is too thin or too small to print, it should be accompanied by a logo containing the contents of the imprint.
