Pucting information:
The identification method of jewelry quality:
1. For foot gold jewelry, you can identify from two aspects, one is the weight, and the other is to see the color. Compared with brass, gold has a strong sense of gold. It is placed in the palm of the hand and has a sense of oppression, because the proportion of gold is 19.32g/cm3, and the proportion of brass is only 8.9g/cm3. The former is the latter of the latter More than twice. The yellower the color of the gold, the better the color. If it is red, the copper impurities are high. If it is white, the silver impurities are high, and the golden color of gold is low.
2, K gold are alloys of gold and other metals, such as silver, copper, zinc, nickel, etc. The gold content of 18K gold is 75%, and the total metal content is 25%. The manufacturer can make K gold into various colors according to the different proportion of other metals, such as yellow -green, black, green and white, etc. Some mermaids are mixed with beads, and the red -green 18K gold pretend to be full gold, and the white 18K gold pretend to be platinum. There are two simple methods for identifying K gold and foot gold, one is hardness, and the other is flexibility. 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, with strong rebellion, and the foot gold ring falls on the ground without such a manifestation.
3. Using gold -plated jewelry to impersonate gold jewelry, this is another way to counterfeit. The jewelry made of brass materials, plated a thin layer of gold on the surface, is very low in value, because its material is hard and it is difficult to impersonate gold. Also under "18kgp". The color of this gold -plated jewelry is different from the color of the real gold, which is obviously reddish, lacks golden colors, and the appearance can be different.
4. Jewelry made of metal nickel materials pretend to be platinum jewelry. Metal nickel is a material for making one yuan coin. It is white, does not oxidize, and looks like platinum material. However, the proportion of the two is different. The proportion of platinum is 21.4g/cm3, while the proportion of nickel is only 8.85g/cm3, which is obviously different.
5, silver and platinum, although the appearance color is similar, it is easier to identify. The proportion of silver is 10.5g/cm3, only 1/2 of platinum. In addition, the sterling silver is soft and easy to oxidize, which will turn black after a period of time, while the platinum is different, which is harder and does not oxidize.
