To purchase gold jewelry, we must first recognize the quality inspection mark of gold jewelry. 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‰.
In particular, consumers need to be reminded that the colors of 18K gold jewelry are yellow, white and red. White 18K gold is an alloy of gold and nickel, zinc, 銀, copper and other elements, and white K gold jewelry is not platinum (白金) products.
The mark of gold jewelry includes the manufacturer code, material and purity, such as: X gold 990, XAu990, X pure gold, 等. その中で, 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” または “thousand gold”. しかし, 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, so many consumers are now chasing thousands of gold, “This situation has led some businesses to do their best. , Replace the artificial gold with thousands of gold, and confuse the two concepts.” The staff of the Municipal Consumer Protection Committee reminded the merchants to simply mark the gold jewelry with solder joints as “thousand gold”, if there is no consumption when selling It is illegal for the person to explain in advance, and once confirmed, consumers must be compensated.
