The code of gold is AU. The national standard GB11887-89 stipulates that each opening (abbreviation of English Carat and German Karat, often writing "K") has a gold content of 4.166%. 8k = 8*4.166%= 33.328%(333 ‰) 10k = 10*4.166%= 41.660%(417 ‰) 14k = 14*4.166%= 58.324%(583 ‰) 20K = 20*4.166%= 83.320%(833 ‰) 24k = 24*4.166%= 99.984%(999 ‰) 24k Kim is considered to be pure gold and became "1000 ‰", but in fact The gold content is 99.99%, and it is 23.988K. The purity of gold is expressed in text. Some gold jewelry has text marks, which are: The gold-containing gold content ‰ The expansion information: The natural pure gold in nature, often contains biochemical elements such as silver, copper, iron, tadpoles, platinum, nickel, tadpoles, selenium, 锇The above are called silver gold ore, more than 20%of copper-containing copper, and 5-11%of those with 5-11%are called 钯 矿 矿 钯 钯 以 以 以 以 以 以 以 以 铋 铋 铋 铋 铋 铋 矿 矿 以 以 以 以 以 以 以 以 以 以.

Gold jewelry refers to jewelry made of gold as the main raw material. The golden chemical symbol is AU, the gravity is 17.4, and the hardness of Mobi is 2.5. Gold jewelry can be divided into two categories: pure gold and gold. The gold content of pure gold jewelry is more than 99 %, up to 99.99 %. Therefore, it is also known as the ninety -nine gold / full gold and red gold. The gold jewelry is a jewelry made of other metals (such as silver and copper) to the golden materials, also known as gold and color gold. Due to the number of other golden careers, different K kills of gold jewelry are formed. In gold jewelry, the pure gold jewelry texture is soft, the teeth are bite, and it is easy to bend. The color is golden, pure, soft, heavy, and feels heavy. K gold jewelery is hard, the teeth are bitter, and the color is yellow in yellow, and it is reduced according to the golden numbers. The white is gradually increased and the yellow is gradually shallow. The feel of gold jewelry is not as heavy as pure gold jewelry. In addition, whether it is pure gold or K has seals, the seals on gold jewelry, useful gold, and an English letter. The corresponding K number is marked. In addition, the jewelry also marks the seal of the origin of different manufacturers. Clated jewelry is plated on the surface of other metal jewelry on the surface of the electroplating method. The color is similar to the real gold jewelry. However, the gold jewelry feels similar, the texture is harder, the teeth are bitten by the yuan, and it is easy to fade with a long time. Some of the poor buildings are not red or white, or they are white or blooming. Bacchus gold jewelry refers to 24 or 22K gold foil on other gold eagle surfaces, such as the voltage of the golden box, which is very low, and its softness is poor. Bao Jinshuo is similar to that of real gold jewelry. The golden light is sparkling and it is not easy to fade, making it difficult for people to distinguish. However, if you carefully observe the depression, angle, back, etc. of the jewelry, you can find that there are uneven gold foil and the phenomenon of tilting edges. Li Bai. In addition, the feel of the gold jewelry is also lighter, the texture is harder than the pure gold jewelry, the teeth are bitten by the meta marks, and it is not easy to bend. Whether it is gold jewelry, gold jewelry, or copper jewelry, it is generally not printed with gold jewelry. Or it is different from gold jewelry. Some jewelry is engraved with English letters GK. Or the signature is vague and crooked. Consumers should identify whether there are printing on the jewelry, whether the printing is in compliance with the above provisions, whether the printing is clear, etc., to determine the authenticity of gold jewelry.
