Diamonds are the hardest substances in natural substances. Diamonds can be engraved with any other gems, but any other gems 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. Fashion male rings. 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. I know the differences between these real diamonds and fake diamonds. I believe that it will be very helpful for everyone to buy diamonds. I hope that when you buy it, you should not be deceived. You must look at the flowers in the fog and open your eyes!
Diamond refraction, luster, diamond appearance and surface characteristics
The method of distinguishing diamonds:
hardness test: Diamond is known as the hardest natural production substance, nothing can be in diamonds The trace is on the top, if the traces can be drawn, it is definitely not a diamond.
This thermal test: Exit at the same time on the debate diamond and other similar items. If the diamond is diamond, the surface of its surface condensed should evaporate faster than the water mist on other items. This is because the diamond has high thermal conductivity Reasons for sex.
Observe reflex light: Use a magnified mirror to observe a very thin matte and glitter reflex light at the waist circumference of the diamond. The characteristics of diamonds are unique.
The growth point: Observe under the magnifying glass, there are often grooves and triangular growth points on the crystal surface of the real diamond.
Pay content for time limit to check for freenAnswer a little bit ~nThere is the following method for you to identify the choice:n1. Use a pen drawing to use a pen to identify the diamond, stick the pen to the ink, and draw it on the diamond. If it is a real diamond, it will leave a continuous and smooth ink line. There will be continuous lines.n2. Rubbing the diamonds on the face has a strong oil absorption. You can rub the diamond on the face and fingers, so that the diamonds are stained with a little oil secreted by the skin. Fake diamonds will not have such characteristics.n3. Prepare a pencil with a pencil, and use a pencil to draw a stroke on the moist diamond. If it is a real diamond, there will be no traces on the surface, and there will be traces of the fake diamonds. In addition, you can also use the water droplet method to distinguish it. Drop a drop of water on the dry diamond. When the water droplets encounter a real diamond, it will be dew -shaped, and it will spread out when it encounters a fake diamond.nOf course, if you go to a regular store, you don't have to worry about encountering fakes.nDo you have any other questions? If you are satisfied with my service, give me a five -star evaluation!nAsk if it is irradiated with light, it is colorful, whether it is real diamond or fakenAnswer fake. The reflection light of diamonds is generally gray of varying degrees, not a color that many people think. If the refracted light shows a rainbow -like reflection light, then this may not be a real diamond, but the high imitation of the diamond, Mosan diamond.nAsk questionsnMore 8nBleak
Teach you a good way to simply identify diamonds. I often ask me. I have not learned professional knowledge like most. I do n’t have a complete understanding of diamonds. How can I distinguish the difference between glass, stones and diamonds without identifying the instrument? In fact, this is a question that is difficult to answer, because after all, people who do not have professional knowledge are still difficult to distinguish, but after I explain the relevant appraisal knowledge of diamonds, if you have a general understanding of diamond knowledge, plus the following I introduce a simple way of identifying, so it may be very helpful for friends with such problems.
The biggest feature of diamonds is the highest hardness and has a strong refractive index, which is shining under light and dazzling. However, its surface is similar to glass, crystal and artificial diamonds, and it is difficult to debate. Accurate identification can only be measured by instruments, and the following methods can be adopted:
1. hardness test
diamond is the hardest natural production substance. No What can be traced on the diamond, if the traces can be drawn, it is definitely not a diamond.
2. Thermal conductivity test
The breath on the defense diamond and other similar items at the same time. The water mist evaporates quickly because diamonds have high heat -guided heat.
3. Observe the reflection light
The observing the waist circumference of the diamond to present a very thin matte and glitter reflex light at the waist circumference of the diamond. The characteristics of diamonds are unique.
4. Looking at the growth point
In observation under the magnifying glass, there are often grooves and triangular growth points on the crystal surface of the real diamond, and there are three categories of rice dumplings: (1) plus The ordinary glass of alumina alumina is easy to enter due to the improvement of the refractive index and color dispersing, but the hardness is low. (2) Use chemical sapphires and colorless spinels to imitate, and the hardness is close, but the refractive index is low and there is a dual refraction. (3) Artificial oxidation imitation, high hardness, good refraction, but reflecting more color light when rotating. Compared with the real yellow and blue color light when rotating, there are obvious differences.
has the above simple identification methods, you can distinguish it yourself when you buy it. However, in the method of hardness testing, we must communicate well with merchants in order to cause unnecessary disputes, because many businesses may not allow this test. I hope that everyone can better understand the charm of diamond while mastering these identification methods!
Ordinary consumers are the best by looking at the diamond certificate.
In general, every province has a special jewelry quality inspection institution, which can go to the quality inspection
