First, the difference between gold -plated and 18K gold is different.
Cin plating jewelry is a layer of gold on the surface of the jewelry. The purpose is to make its surface have a good luster, antioxidant, gold plating is divided into two categories, one is plated in homogeneous materials, and the other is different. Greed quality. Homogeneous material gold plating refers to the surface of the gold jewelry, and heterogeneous materials are plated in heterogeneous materials.
and 18K gold are alloys with a gold content of at least 75%, that is, alloys with a gold content of 18/24, and the remaining 25%are other precious metals, including platinum, nickel, silver, and gold.
, the identification method of gold -plated and 18K gold:
1, only by weight without damage to the surface of the jewelry, it is to use the hand. Because the density of the gold -plated internal materials and the density of real gold are different, 18K gold jewelry is much heavier than gold -plated jewelry. Therefore, you only need to use your hands. If you feel slightly sinking and a folding feeling, then it is 18K gold jewelry. This method requires comparison. If there is no contrast, professional jewelry appraisers are required.
2, look at the product label steel print, the real 18K gold product is engraved with the steel printing of G18K, 18K or AU750, G750, and the tag name is 18K gold; Some of these accessories are only 18K gold plating.
3, from the point of view of the purchase, the true 18K gold is real gold, and it must be sold by the golden sales unit approved by the People's Bank of China, but the electroplating is not required.
4, look at the after -sales service, the 18K gold of the electroplating cannot be repaired, and once the color is broken, it can be thrown away. You can sell it as a gold.

The advantages of pure 18K gold:
18k gold jewelry not only has the precious value of gold, but also because of its perfect proportion, strong ductility, high hardness, and variable color. Used in jewelry design, you can fully play complex and exquisite creative performance.
18k gold's hardness and toughness are higher than platinum. It can maintain a stable nature in various environments, not easy to wear or deform, and can give diamond solid protection. Complex and fashionable styles can also inlaid diamonds well, so they are often used to match diamond inlaid.

The two are different in terms of gold content, density and price.
1. Different gold content:
plating 18K gold refers to the surface of the jewelry is 18K gold, and under the surface layer of 18K gold is other metals; and 18K gold refers to 18K gold itself, that is, 75% gold content 75% The alloy.
2, different weight:
18k gold is large than the density of gold plating. Because the density of gold is larger than the density of the electroplated metal, the density of pure gold is large.
3, the price is different:
Under the same accessories: 18K gold is high in the price of 18K gold.
The identification methods of the two are as follows:
1, hardness:
Thenicity of K gold and foot gold is mainly hardness and elasticity. The hardness of K gold is harder than the foot gold, the more pure the foot gold, the soft, and the teeth can bite the traces, while the K gold does not work. The K gold ring falls on the ground and has a strong rebellion, and the foot gold ring falls on the ground without this effect.
2, color:
jewelery made of brass materials, and a thin layer of gold on the surface. Its value is very low, because its material is hard, it is difficult to impersonate gold, but some people take down It is sold as 18K gold, and the seal of the jewelry is still "18KGP". The color of this gold -plated jewelry is different from the color of real gold, which is obviously reddish and lacks golden colors.
3. See the product label steel print:
The 18K gold products are engraved with steel prints G18K, 18K or AU750, G750, labels are 18K gold; Or 18K casting gold, etc. Some of these accessories are only plated 18K gold on the surface.
3, from the place of purchase:
true 18K gold is real gold. It must be sold by a golden sales unit approved by the People's Bank of China, and the electroplating is not required.

18K refers to the purity of the gold in jewelry in jewelry of jewelry is 18K. 18K is not a weight, but a proportion. Theoretically, 100%gold content is 24K. In fact, it is impossible to have 100%purity gold. Our country stipulates that the gold with a purity above 99.6%(inclusive) is 24K. 18K is the golden ratio of 18, 18/24 = 0.75, which is 750 thousandths. Therefore, the mark of 18K gold is AU750, 18K or G750.
