Most of the gold jewelry sold on the market is equipped with the inspection mark of the quality inspection agency, which clearly indicates the gold content and weight of the jewelry. 999 gold is also called thousands of gold, the gold content is not less than 999‰; 990 gold is called gold, the gold content is not less than 990‰; 22K gold is not less than 916‰; 18K gold is not less than 750‰ ; The gold content of 14K gold is not less than 585‰; the gold content of 9K gold is not less than 375‰.

The mark of gold jewelry includes the manufacturer code, material and purity, soos: X gold 990, XAu990, X pure gold, ens. Onder hulle, the letter X is the manufacturer code. When jewelry is made of precious metals of different materials or different purity, the materials and purity should be expressed separately. When the jewelry cannot be printed because it is too thin or too small, it should be accompanied by a logo containing the content of the stamp.
According to an inspector from the City Gold Jewelry Testing Center, each piece of gold jewelry is marked to indicate whether the product is "full gold" of "thousand gold". Nietemin, in reality, most people do not know the real difference between the two. According to personal feelings, thousands of gold must be of high purity, soveel verbruikers jaag nou duisende goud na, "Hierdie situasie het daartoe gelei dat sommige besighede hul bes doen. , Vervang die kunsmatige goud met duisende goud, en verwar die twee begrippe." Die personeel van die Munisipale Verbruikersbeskermingskomitee het die handelaars daaraan herinner om bloot die goue juweliersware met soldeerverbindings te merk as "thousand gold", indien daar geen verbruik by verkoop is nie Dit is onwettig vir die persoon om vooraf te verduidelik, en sodra dit bevestig is, verbruikers moet vergoed word.
