Chinese jewelry and gold bracelets have no brand steel seal, only pure gold steel seal is true. According to the new national jewelry naming standard for gold jewelry, gold jewelry sold on shelves needs to be stamped with gold content. Common gold bracelets are pure gold, AU999, AU999.9 and so on. In addition to the gold seal, there are also brand seals (usually letters) for gold jewelry, which are available in general jewelry brands, but may not be available in small gold shops.
