Classification of gold jewelry materials

'Pure gold' is usually divided into pure gold and thousand pure gold. Red-yellow in color, soft in texture and dazzling luster. But absolute pure gold does not exist. As the saying goes, 'gold has no pure gold'. With the modern science and technology level, reagent gold with a purity of 99.9999% can be extracted specifically for use as standard chemical reagents. Due to the high production cost of reagent gold, only from the use value of jewelry, the use of reagent gold to make jewelry is of little significance.　Today, the author will introduce to you the classification of gold jewelry. 1. 'Pure gold' jewelry 　　 'pure gold' is usually divided into pure gold and thousand pure gold. Red-yellow in color, soft in texture and dazzling luster. But absolute pure gold does not exist. As the saying goes, 'gold has no pure gold'. With the modern science and technology level, reagent gold with a purity of 99.9999% can be extracted specifically for use as standard chemical reagents. Due to the high production cost of reagent gold, only from the use value of jewelry, the use of reagent gold to make jewelry is of little significance. At present, there are three kinds of pure gold fineness in the Chinese market: '49 goldCommonly known as pure gold. 2. K gold jewelry 　　 K gold is an alloy made by adding some other metals to pure gold to increase the hardness, change the color tone and lower the melting point. Due to the different proportions of other metals added, the color, hue, hardness, ductility and melting point of K gold are all different. The characteristics of K gold jewelry are that it uses less gold, has a low cost, and can be formulated into various colors, and is not easy to deform and wear. Especially after the gems are inlaid, they are firm and beautiful, showing the precious beauty of the gems. Therefore, it is widely popular in many cities in our country. The color of K gold jewelry is relatively rich. At present, the successful researches include red K gold, orange K gold, yellow K gold, green K gold, blue K gold, cyan K gold, purple K gold, gray K gold, black K gold, White K gold, white K gold, because of its color and luster similar to platinum, especially with a layer of rhodium, is more elegant and can be fake, but the price is much lower than platinum, so it is favored by many people. There are three main series of white K gold formulas, namely: gold and palladium, gold and nickel, gold and silver, or a combination of alloys, which can form white gold.
