General jewelry seals should contain the manufacturer's code, the name and contents of precious metal materials, and must have contents. Thousands of gold refers to thousands of gold with a gold content of not less than 999, 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.
