Look at the color: the higher the purity of the gold jewelry, the deeper the color. If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so-called green gold contains only silver ingredients in gold); dark red yellow color is more than 95 %, light red yellow 90-95 % The pale yellow is 80-85 %, the cyan is 65-70 %, and the white light is only 50--60 % white light. The slightly yellow and white are less than 50 %. Generally, Qiqing, Eight Huang, and Jiu Chi can be used as a reference. ： weight: The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40 % heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, and the fake gold jewelry feels lightly. This method is not suitable for gold jewelry inlaid. Itt the hardness: pure gold is soft and low. It can draw light marks with nails. Teeth bite can leave tooth marks. High -quality gold jewelry is low in color. The method can also test the hardness, the pure gold is soft, it is easy to bend, the lower the purity, the less likely to bend. Listening to the sound: The real gold with a color of more than 99 % is thrown to the hard ground, which 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. In fire burning: The jewelry of the deformation of the jewelry will be used to use the fire (do not melt the jewelry), and observe the color change after cooling. Is not pure gold. Generally, the lower the color, the stronger the color, and the darkens are all, indicating that it is a fake gold jewelry. Themids: Domestic gold jewelry is all prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; Those who are lower than LOK can not play the K -printed number according to regulations. At present, illegal elements are commonly used to manufacture fake cards and imitation stamps in the society. They use rare gold, Asian gold, and even brass to impersonate real gold. Therefore, the identification of gold jewelry must be comprehensively determined according to the sample to determine the true and false and the quality of the real. This information 18K gold identification method: Ogly 18K gold proportion is far lower than real gold, and it is obviously lacking weight with the hand; The luster is not bright, the connection is large, and the golden skin that seems to be seen in a closer look at it. There are traces of retreating color when the old goods are visible. The really 18K gold craftsmanship is delicate and shiny; The steel print is G18K, 18K or AU750, G750, and the label is named 18K gold; the fake 18K gold steel print is 18kgp or 18kgf, etc. The label is called alloy or 18K casting gold. From the point of view of the purchase, the true 18K gold is real gold, which must be sold by the golden sales unit approved by the People's Bank of China; The after -sales service, fake 18K gold cannot be welded, once the color is broken, it can be thrown away; The true 18K gold can be repaired and clean and polished. If it is accidentally broken, it can be repaired. Other styles can be processed. The 14K, 18K platinum, white 18K gold, etc. on the market are not platinum accessories, but alloys of gold, silver, nickel, copper and other elements, that is, white K gold, and platinum is two concepts. Platinum is called platinum. The chemical nature is more stable than gold, and the price is more expensive than gold. It is used to make high -end jewelry. The "PT900" or "PT950" seen on the products of jewelry stores represents 90%and 95%of the platinum content in the jewelry. Baidu Encyclopedia-18K gold
18k gold is far lower than the real gold. If we weigh 18K gold with our hands, we can find that 18K gold has no sense of weight. The structure is slightly rough, the luster is not bright, and the connection is large. If you look closely, you can see the golden skin that wants to fall off. The texture of 18K gold is simply identified to the authenticity of 18K gold, mainly to see the weight and workmanship of 18K gold. 2, look at the logo and after -sales
I we can see the label seal of 18K gold. It is 18kgp or 18kgf, etc., and the label is called alloy or 18K casting. Secondly, we can also watch after -sales service. Fake 18K gold cannot be welded. Once the color is broken, it can be thrown away; and the real 18K gold can be repaired and polished. You can also sell it as a gold. It can be seen that the logo of the true and false 18K gold is still very different from the after -sales. 3. Look at the steel seal to see the steel print of the 18K gold necklace, because as long as it is a regular and qualified gold jewelry, there are steel prints, such as 18K or 750, G18K, etc. of 18K gold jewelry. The second is that the fake 18K gold is carefully observed with the naked eye, because the really 18K gold jewelry is shiny and exquisite in the luster. If you look closely, you can see the golden skin that is about to fall. Even if you accidentally dirt or damage the 18K gold, you can also repair the cleaning and polishing. If you accidentally break it, you can also repair it. You can even process it into other styles.
This expansion information: If discrimination 1, whether gold has white highlights If you see a white highlight, because gold and 铱 cannot be fused together, it means that the gold is mixed with 铱. 2, measured the proportion. In the weight of a pure gold bars with an balance, and then put the gold bars into a measuring cup and flood the gold bar. Then put the detected gold bars in a measuring cup, whether the scale of the water rises or decreases. As long as it changes, it means that the gold bar is not pure gold. But if it is gold jewelry, this method is not applicable because there is air in gold jewelry. 3, real gold is not afraid of fire. This gold bars or gold jewelry burned for a while to observe its changes. Because the oxidation reaction occurs with oxygen in the air, the gold bars with insufficient purity will become gray; and the color of the pure gold will be red after the fire is baked. However, this method may be destroyed to jewelry. Reference materials: Baidu Encyclopedia-18K gold
Hello: Gold can be made into 24K, 18K ... and other gold jewelry. The jewelry marked "18K" (or G750) refers to the pure gold content of 18 cents, that is, 75%gold plus 25%of other metal alloys (such as silver, tadpoles, zinc, nickel, etc.) A kind of jewelry. 18K gold jewelry not only has the valuable value of gold, but also has the advantages of strong proportion of components and has strong ductility, high hardness, and changeable color. It can be used in jewelry design and can fully play complex and exquisite creative performance. The amazing gold jewelry such as K-Gold, which is amazing in the market, is mostly made from special alloy like 18K gold. In the trend of world jewelry, K gold is the mainstream, and Western fashion people even use the unique and unique K gold jewelry to highlight their personal style; because K gold fashion can always meet the needs of contemporary young people, so it is in this way, so it is in this way, so it is in this way, so it is in this way. The status of the fashion industry is enduring, forming a popular style wearing K gold jewelry. 18K gold contains 75%gold, so it still has the characteristics of strong gold ductility, and it is easy to shape into various shapes. And due to the combined 25%of other metals, the hardness enhances the hardness, and it is not easy to deform or scratch. It can also create a brighter and rich color, so that the jewelry design can have a higher level of artistic performance, so it is widely suffered widely The jewelry industry is favored, and it is used in large quantities in the fine and fine gold jewelry design or gem inlaid. All kinds of complicated and delicate gold jewelry design in the market, such as preparing a mesh, slim -shaped fringed, lace -shaped design, a few chaotic snake patterns or elephant leather design, etc. Essence If identifying gold requires certain experience. Simply introduce some identification methods. but it is best to go to the gold shop! (1) See color: the higher the purity of the gold jewelry, the deeper the color. If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so-called green gold contains only silver ingredients in gold); dark red yellow color is more than 95 %, light red yellow 90-95 % The pale yellow is 80-85 %, the cyan is 65-70 %, and the white light is only 50--60 % white light.

(2) Type weight: The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40 % heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, and the fake gold jewelry feels lightly. This method is not suitable for gold jewelry inlaid. (3) Look at the hardness: pure gold is soft and low. It can draw light marks with nails. Teeth bite can leave tooth marks. High -colored gold jewelry is low in color. The bending method can also test the hardness, the pure gold is soft, it is easy to bend, the lower the purity, the less likely to bend. (4) Listening to the sound: Throwing the real gold with 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) Burning with fire: Burn the jewelry to burn red (do not melt the jewelry) with the fire (do not melt the jewelry), and observe the color change after cooling. The degree of darker is not pure gold. Generally, the lower the color, the stronger the color, and the darkens are all, indicating that it is a fake gold jewelry. (6) Seeing the mark: Domestic gold jewelry is all prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; 18K gold, "18K", indicate "18K" Words, those who are lower than LOK, can not play the K -printed number according to regulations. At present, illegal elements are commonly used to manufacture fake cards and imitation stamps in the society. They use rare gold, Asian gold, and even brass to impersonate real gold. Therefore, the identification of gold jewelry must be comprehensively determined according to the sample to determine the true and false and the quality of the real. The accuracy of gold jewelry has two common methods. (1) Testing gold stone method: Select the black test gold stone with delicate texture, use the standard gold medal (pair gold medal) with different gold content (on the gold medal), and then draw the gold jewelry sample you want to identify Sales, remove the impurities with concentrated nitric acid, and find out the traces left on the test gold stones compare with the traces of the tested slices that are drawn, and find the same color as the jewelry sample. The accurate gold content of the sample. (2) Chemical method: also known as reagent test method. Gold is insoluble in separate nitric acid, sulfuric acid, and hydrochloric acid, and silver and copper ingredients can be dissolved with nitric acid. Take gold decorative sample. Putting nitric acid on a certain part, if gold will not change color, if it is silver products, it will generate silver oxide and turn black; For gold jewelry with a gold content of more than 95 %, test with nitric acid, the surface changes very small.
18K gold is a alloy made of gold and other metals. Because 18K gold has high hardness, 18K gold's melting point is low, 18K gold is often used to make a variety of jewelry, but 18K gold and gold are often in many cases. People are not clearly distinguished, I don't know how to identify 18K gold.-"Quote from the Internet"
