1. Look at the color The different luster and color of the gold can be generally distinguished from pure gold, K gold, real gold, fake gold. The old -fashioned old -fashioned "Qiqing Eight Yellow Nine Five Red and yellow leucorrhea gray pairs of gold" circulating is the purity of the gold.
2. Seeing the mark The domestic gold jewelry is to be used as a kill. It indicates that 24K means that the purity is more than 99.6%, and the 18K indicates that the purity is above 75%.
3, see hardness The gold with high color, can leave traces with large head needles or nails. More than 97%of gold jewelry, after twisting two or three times, wrinkles appear at the bending, also called fish scales; about 95%of gold jewelry, it feels hard when bending, and the fish scales are not obvious; about 90%of the golden gold golden gold; The jewelry is very hard when the bending is bent, without fish scales; gold jewelry containing more impurities, bend twice or three times to break; if it is made for raw gold, the bend is broken.
4, listening to the sound The real gold with a color of more than 99%to throw it on the hard ground, it will make a tap sound, there is no rhyme or elasticity. The fake or low golden sound is crispy but no dullness. Generally, the sound of "Dangdang" is emitted, and there are surplus sounds.
5, 掂 weight The proportion of gold is 19.3g/cm3, which has a large relationship with the proportion. When the proportion is close to 19.3, the higher the pure gold. Looking at whether it is commensurate with the size of the size, the shape is large and lighter may be adulterated. But generally in the hands, if you feel slightly sinking, you can perceive the real gold jewelry, which shows that the gold body is small and heavy. You should be vigilant for the stupid and light jewelry, and carefully discern whether for fakes or semi -fakes.
6. Test soft The higher the color of the gold jewelry, the softer, the more elastic. Low -colored steel is hard; those with heavy mixes are elastic, crispy and easy to break. The pure gold is soft, and it is generally not used to make embedded jewelry. Therefore, all inlaid gold jewelry claims to be 24K and there must be fraud.
7, scraping porcelain plate In a glazed porcelain plate. If not, you can buy a porcelain in the home improvement store. Scrape the porcelain plate with a golden device. If the black scratch is left on the porcelain plate, your gold ware is not a real gold. If the scratch is golden, it is true gold.
This this method can make the fake gold original, but your gold ware may be scratched.
8, nitric acid testing method This put the goldware into a small stainless steel container, drop a drop of nitric acid on the goldware, and observe the reaction. If the acid is green, then this golden device is either made of ordinary metals or gold plated. If it is golden, it is gold -plated copper. If it presents milk, it is gold -plated silver. If there is no reaction, then this golden device is true.
This nitric acid test is a good way to distinguish the authenticity of gold, but because nitric acid is not easy to obtain, and it is more dangerous to operate at home, it is recommended that you give it to the jewelry dealer to do it.

The color of the surface on the surface after being burned will not change. Due to the texture of the fake gold, the color of the surface will gradually turn black and affect the texture. 2. The hardness of the hardness at home can see the hardness of the gold and falseness at home. The real gold texture is soft, the hardness is low, and it is easily bent. The fake gold texture is hard, the hardness is high, it is not easy to be bent, and it will be broken too hard. 3. The identification can be seen at home to identify the authenticity of gold. The real gold needs to comply with national regulations during the production process, so it is required to print the identification of the purity of 999, 990. Fake gold usually does not have a purity logo due to material and craftsmanship.nMagnet testing gold is not a magnetic metal, you can test it with magnets. If your gold is attracted by magnets, it proves that it is not true gold. If your gold is not attracted by magnets, it may be real gold, but there are many non -magnetic metals. This method can only exclude poor quality of gold. Look at the surface of the surface gold jewelry must be bright and clean. There are no marks of obvious processing, no obvious sharp corners, and the feel is smooth. On the surface, the color gold cannot be seen on the surface of the pores, impurities, etc. This means that the higher the purity of gold, the deeper the color will be. Showing a dark yellow color gold with a purity of more than 95%; presentation of light red yellow gold, a purity of 90-95%; showing pale yellow gold; 80-85%of the purity; presentation of blue and yellow gold The purity is 65-70%; the purity of gold with excellent white light is only 50-60%of the purity; and the gold is slightly yellow and white, and the purity is less than 50%. Listening to the sound of more than 99 % of the real gold to throw the ground on the ground, it will make a "tap" sound, there is no rhyme or elasticity. The fake or low golden sound is crispy but no dull, and generally makes a "Dangdang" sound, the sound is bright and crispy
