For most people, it is difficult to distinguish the authenticity of diamonds by relying on the naked eye. How to distinguish the authenticity of diamonds? Here is a way to distinguish between true and false diamonds that are convenient and fast. Touch the diamonds with your hands to gently touch the crystal surface of the diamond with your fingers. It will have a sticky feeling. This sticky is unique to the real diamond, and the fake diamonds will not produce. Because diamonds have a kind of affinity for fat, and some trace hand oil will secrete the skin of the human finger. This kind of skin oil and the diamond crystal contact will have a sticky feeling. Use a pencil to distinguish the authenticity of diamonds. This method is invented by an expert from the former Soviet Union. Before the identification, the diamond should be wet with water, and then gently scratched the crystal surface of the real diamond with a pencil. There is no trace; but if it is a fake drill made of glass, crystal and other materials, marks will be left on the surface. The water drop test distinguishes the real drop of diamonds on the diamond. If the water droplets can keep the spherical shape for a long time, it is the real product, and the water droplets on the imitation product will spread relatively quickly. Harbin gas experimental diamonds have a breath on the diamond. If the water on the diamond disappears immediately, it is a real diamond. If the water and gas stay on the diamond for a few seconds before they disappear, it is a fake diamond. Sensory tests Diamonds to contact diamonds with tongue at room temperature at room temperature. You will obviously feel that real diamonds are much cooler than imitation products. Oil testing Diamonds The authenticity of the diamond uses a special pen or ballpoint pen with an oil -based ink, and drawing a line on the countertop of the diamond will leave an uninterrupted straight line. Other imitation products are not intimate, leaving intermittent points at the line.
Diamonds can be engraved with any other gem, but any other gemstone can be engraved with diamonds. It can also be carved with "standard hardness meter". The hardness is less than 9 degrees, and it is a fake diamond. Diamonds are also intimate. If a pen is drawn on the surface of the diamond, it becomes a continuous straight line, while other gems are intermittently intermittent. The above methods have a certain reference value in identifying diamonds. You can also observe through 10 times large mirror. Under 10 times the large mirror, most diamonds can see the flaws. There are triangular growth patterns. The surface of the diamond has "fire" light such as "red, orange, and blue". shining. The most accurate and reliable method is to use the "heat -guided meter" to measure heat -conducting data to distinguish between true and false diamonds, but the price of "thermal guide" is more expensive. Because diamonds are noble and luxurious jewelry, currently the market is used in the market to replace or call diamonds with cheap gems, artificial gemstones, and even glass. There are many commonly used fake diamonds: ① vermiculite: very similar to diamonds, is diamonds, diamonds Best supplies. The appraisal method is that because the vermiculite has polarization and a large double refractive index, when the vermiculite edge after 10 times the large mirror is used to observe the processing of the processing, it can be seen from its top surface. Shadow, and diamonds have no phenomenon. ② Glass: The discount rate of glass is very low, and there is no flashing color light of diamonds; especially sinking into the water, the glass products are glory at all, and immediately expose the horse's feet. ③ Soviet diamonds: Cube oxidation, the earliest was successfully developed by the Soviets, hence the name. Soviet diamonds are artificial compounds, but they are very close to natural diamonds in terms of scattered and folding. They also have the seductive appearance of "fire". But its hardness (8.5) can be distinguished from each other. And thermal conductivity is much lower than that of diamonds, which can be identified by the "hot guide" and accurately distinguish it. ④ Crystal: Although the crystal is a natural mineral transparent crystal, it looks like diamonds after processing, but the colorful light of diamonds lacks diamonds.

If the water is not dispersed for a long time, it can prove that it is a natural diamond. If the water droplets will spread soon, it indicates that it is an artificially synthetic diamond or a inferior diamond. Of course, this method of identification is mainly aimed at some relatively large bare diamonds. If you buy a diamond ring, the implementation of this method is not strong.n2.nFriction method. We all know that the hardness of natural diamonds is very high, and it also has very strong toughness. Therefore, if we use a relatively rough sandpaper to polish the surface of the diamond, there will be no scratches. Conversely, the surface of artificially synthesized diamonds is easier to leave scratches.n3..nProfessional identification. Except for the above simple ways of identification. We can also go to some professional diamond identification agencies to identify the direct pseudo of diamonds.nQuestion where there is a diamond identification agencynAnswer Hello, you can go to the local jewelry shop and you can identify itn6 morenBleak
Diamonds are long -lasting, a forever spread. Many people first choose diamond rings as rings when they are proposed or married, but they are worried about whether the diamonds they buy are fakes, and they don't know how to identify the authenticity of diamonds. The following editors have compiled some skills to identify diamonds.
The knowledge about diamonds before buying. When buying, the merchant will issue bills. If you have any questions about the quality of diamonds, you can choose a qualified gem testing agency for testing, and directly negotiate the test report with the bill with the bill.
In addition, we can identify diamonds in the following ways:
The first type is required to provide a diamond -related certificate. Each diamond product like Levis is equipped with a test certificate from a national testing agency.
The second type, dripping oil and dripping test, diamonds are close to oil. The first drop of oil on the diamond will be quickly dispersed and covered on the surface of the diamond. Clean diamonds, otherwise it will affect its luster. Diamonds are also water support. A drop of water on the diamond table will find that the droplets can roll on the surface of the diamond for a long time. If the water droplets are spread quickly, it indicates that this is not a diamond.
The third type, qi test method. Natural diamonds have a very large characteristic, that is, the heat transfer ability is very strong, and the heat spread is very fast. When we test, we can put the diamond near the mouth. Just blow it gently, and the diamond will have a layer of light mist. At this time, we need to observe the situation where the fog is volatile on the diamond. It takes a short period of time if the fog is on the diamond, indicating that the diamond is fake. If the fog is blown away, there is no stay, indicating that this is a natural diamond.
The fourth type, white paper drawing test method. We use a pen -frame line on a piece of white paper to put the diamonds that need to be determined online. When placing it, it faces the front, and then directly observe it with the naked eye on the back of the diamond. If you can't see the straight line pressed under the diamond, it proves that the diamond is true. The reason is that the diamond itself has a strong refractive index. When it is affected by the external light, its reflection force on the light is also very strong, resulting in very low perspective.
The fifth type, the proportion test method. We can buy a proper liquid on the market. It measures the proportion of gemstones and tests the true and false diamonds. The test is simple, because the proportion of the natural diamond is fixed at 3.52, and the proper liquid is 3.32, so if the natural diamond is placed in a 3.32 specific liquid, it will sink into the water. Conversely, if the diamond floats on the water, it is determined that the diamond is fake.
The method of identification of diamonds. The above is just the five of them. This can only be used as our usual ordinary test. The domestic jewelry industry is mixed, and the diamond ring brand is endless. Do not want to buy counterfeit products and counterfeit products. It is better to know how to identify the authentic diamonds and reduce the chance of being deceived. Of course, when buying diamonds, it is better to buy a brand jewelry and diamond shop with a high reputation.
