A diamond is a precious piece whose originality has to be tested, and whether diamonds are fake or not can be revealed in many ways. One of the fastest and most accurate ways to do this is to use a device for testing diamonds called a “diamond tester”.
The diamond tester is a very useful device that can be carried in a pocket. These devices contain a small needle to be placed on the stone to be tested. If the diamond under test is not fake, this will be reflected on the screen of the device; at the same time, the device can emit a vocal signal. The way diamond testers work is that heat passes through the stone, indicating a statement about the authenticity of the diamond. Also, some devices use electrical conductivity. Typically, these devices attributed as the most reliable diamond testers.
In a conventional diamond tester, the metal tip is first heated and then applied to the cold surface of the diamond. As a result, heat transfer is provided. The heated metal tip of the device used for the test heats the diamond. Thus, a match is achieved by making a reading between the diamond and the tester. As a result, it is revealed whether the diamond is a real diamond.
On the other hand, nowadays the difference between fake diamonds and real diamonds have become much smaller as a result of very good imitation. Recently emerged testers have a different system for comparing the properties of diamonds and their imitations. These testers try to reveal different characteristics in today’s imitations and simulations.
How Does a Diamond Tester Work?
Diamond testers function based on a different operating principle based on the fact that different gemstones conduct heat differently. Depending on the type of stone, heat passes through the stones differently; For example, the transfer of heat takes place differently between a diamond and cubic zirconia.
Through diamond tester devices, the level of heat passing through the stone is determined and the level of reality is revealed. In some tests, it is the electrical conductivity used in the test phase – the underlying principle is the same; the difference is that electricity is used, not just heat.
Portable diamond testers are very useful in situations where the authenticity of a diamond is required to be learned, as they are functional and portable. At the same time, diamond testers are frequently preferred as they are very meticulous in reaching the results and save time and effort.
Types of Diamond Testers: Electric and Heat
If you are planning to buy a diamond tester, you may not know enough about which type of diamond tester is better. Recent research has proven that diamond testers that show results through electrical conductivity are much more successful than diamond testers that provide conductivity through heat.
Although these devices cost a higher amount than devices that use thermal conductivity, they are preferred and should be more preferred due to their more reliable results. By contrast, test devices that use heat are much more affordable; however, the accuracy and precision of its results are lower than devices using electrical conductivity and as a result, may not give very good results.
If you are professionally dealing with diamonds and you will be testing the authenticity of multiple diamonds in one day, the recommended device is a device that uses electrical conductivity. This is because a type of “fake diamond” called moissanite can be detected as a fake, using only electricity. Moissanites are dazzling just like diamonds, but they are not diamonds; their structure is different from a diamond. With the development of technology, many test models have proven reliable in the market age, but using an electrical conductivity tester is the option that brings you closer to reality.
How Reliable Are Diamond Testers?
When you decide to buy a diamond tester, there are a few things to consider. First, know that the device you are using must manifest through the different electrical conductivity between moissanite and diamond. However, the latest devices consist of combining heat and electrical testing to achieve the highest accuracy results.
Another advantage is that these devices detect and signal when the stone is not touched accidentally, for example, if the metal setting is touched. In a situation where the tester does not recognize the metal, even if the diamond is fake, touching the setting by mistake may give a misleading result as the diamond is real. Therefore, using the device is as important as owning it for them to deliver reliable results.
Diamond testers are among the most common and accurate tools for determining the authenticity of a diamond. However, you should know that there is a possibility that testers using thermal conductivity might confuse moissanite with diamond. This is because how both stones conduct heat are very similar. This is a big problem when determining originality. To solve this problem, a device that uses electrical conductivity, not thermal conductivity, is used; Because how moissanite and diamond to conduct electricity is quite different from each other.
The system in a multi-tester is that this device combines the thermal conductivity test with the electrical conductivity test. Because most diamond multi-testers work in this way, one of the most important features to look for when choosing a diamond tester is that the multi-tester has a system that alerts you when it touches a metal fork instead of a precious stone. The reason this criterion is so important is that a metal nail is considered a diamond by a device without warning related metal.
The Relationship Between Diamond Testers and Ultra Violet Light
Some of the diamond tester models have a UV light and raised an expectation that UV light could be used to test diamonds, but this belief is not true. It is not possible to tell the difference between diamonds and other stones such as moissanite through UV light. A useful thing to know is that diamonds are randomly fluorescent, and if the result is the same response to all the stones that make up a ring or your diamond brooch, whether they are fluorescent or not, then they are probably not diamonds. If some fluoresce while others do not, then they are more likely to be diamonds.
UV light, however, points out the possibility of starting when natural diamonds and synthetic diamonds are compared. For examining diamond ‘parcels’, there is a need for a long wave UV lamp AND a short wave UV light. So, you should see stones in a dark room and on a background in the color of black. Natural colorless diamonds, almost 40% fluorescent, often fluoresce more under long-wave than under short wave. Some synthetic diamonds react in the opposite direction; fluorescence is weak under longwave and strong under short wave.
Therefore, in the case of purchasing loose diamonds, diamonds should be examined under UV light to assess the possible mix of ‘natural’ and ‘synthetic’. On the other hand, checking a diamond under UV light may not mean anything to you. This is because such information is suitable for interpretation by jewelry experts or professional diamond retailers. So, a non-professional jeweler may not be able to sharpen these and not be an expert in this field.
Lab Diamonds and Diamond Test
Can a diamond test be applied to carbon lab diamonds to assess their authenticity, just like natural diamonds? The answer to this question is in some cases, yes and in some cases no. Testing diamonds for these diamonds takes place in several ways. Knowing which tests to apply to synthetic diamonds, which tests they will pass, and which ones will be moved is as important as knowing about real diamonds. Carbon lab diamonds can pass tests for their physical and chemical properties, but when these diamonds are evaluated with the eyes of an expert, these differences become quite obvious.
Natural and laboratory-grown diamonds have the same crystal structures; that is, their chemical composition is similar to each other. As such, the terms “synthetic diamonds” or “manufactured diamonds” are not used to refer to the diamonds themselves. So, chemically speaking, these lab diamonds are also real diamonds. The designations “synthetic” and “manufactured” refer to the laboratory-based manufacturing process.
The GIA has detected a lot of synthetic diamonds fraudulently mixed with natural diamonds. And making these definitions is not as difficult as it seems, it is easy. A few signs are tasked with showing the lower value of carbon lab diamonds. These tests are done for inclusion and clarity evaluation. Most lab-grown diamonds are readily generated synthetically.
At the same time, the other feature that gives away laboratory diamonds is inclusions. There is a metal solution that is used to help lab diamonds grow, and this indicates metallic inclusions in carbon lab diamonds. These inclusions are visible when viewed at 10 times magnification and become quite obvious even if a magnifying glass is used and a cursory examination is performed.
A thermal conductivity probe or a “diamond tester” is used to accurately identify fake diamonds. As diamonds are highly effective heat conductors, they rapidly absorb and distribute the heat applied to their surface. A tester for electrical conductivity also provides a useful measure. While many fake diamonds do not conduct electricity well, diamonds conduct electricity very well.
Finally, sets that have high profile weight diamonds apart from other gems. Scales produced for weighing carats may differ slightly between stones in terms of weight. If a stone differs too much, it indicates that the stone is not a real diamond, indicates that it is synthetic.
Well, the question arises of what all this means for synthetic diamonds. The value of a diamond depends on its worth and level of perception in each case. It is revealed by opinion polls and diamond price points that synthetic diamonds are not just as sought after and valuable as natural diamonds. Of course, diamonds are seen as an eternal expression of love. So many people are hesitant to trust lab-made diamonds.
The story of no synthetic diamond is the same as the story of a natural diamond, and so as a symbol tasked with expressing something timeless, the diamond should also be timeless. Most people are hesitant about the production journey of a synthetically created diamond. Therefore, a synthetic diamond has not yet been able to fully replace diamonds, the timeless symbol of love. When choosing between natural diamonds and synthetic diamonds, the problem in customers’ minds is exactly the problem of trust. If you doubt the authenticity of your diamonds, have them checked by a professional diamond analysis.

5 Home Tests to Tell Whether Your Diamond Is Real or Not
Whether a diamond is genuine is the most crucial issue in purchasing a diamond. Well, if you do not have a tester but still need to check if your diamond is genuine, would you like to know how to find out? There are some tests done at home, on your own, to check if a diamond is genuine, without the need for a professional jeweler.
Diamonds have a few “fake” equivalents that can effortlessly be befuddled with genuine precious stones – common stones that have a solid likeness to jewel, colorless sapphire, colorless topaz, and colorless zircon. There are too lab-created diamonds like yttrium aluminum garnet, manufactured cubic zirconia, and gadolinium gallium garnet engineered moissanite that looks like real diamonds to the average individual. This likely causes that you are curious about how to tell on the off chance that a diamond is real if there are as well numerous comparative.
Experts recommend that you do your part. “The biggest misconception is to think that there is only one kind of ‘fake’ because there are many imitations of diamonds in the jewelry market today, not just one or two. Of course, you want your stone to stand the test of time. Therefore, it is advisable to consult a reputable jeweler to question whether a diamond is genuine. However, if you want to do this yourself, you can try at home to find out if a diamond is fake. There are five simple home tests.
Test Using Fog to Distinguish Real Diamond from Fake Diamond
To find out if your diamond is fake, bring your jewelry close to your mouth and mist it with your breath as if it were a mirror. If the diamond remains cloudy for a few seconds, it is probably fake. If it is a real diamond, the diamond does not fog easily as the condensate does not stick to the surface.
Test Using Water to Distinguish Real Diamond from Fake Diamond
This method is one of the easiest to try at home. To do the water test, take a glass and put water in it. The type of water you put in is not important. Drop your diamond into the glass you filled. Because diamonds have a high density, they will sink to the bottom when placed in water. So if the diamond is floating on the top or in the middle of the glass, the diamond is fake. Physics will give you the right answer.
Test Using a Magnifying Glass to Distinguish Real Diamond from Fake Diamond
Another home test to use to determine if your diamond is genuine uses a magnifying glass. Hold a magnifying glass at the diamond and look at your diamond through the glass. Look for flaws in the stone If you can’t find any flaws, the diamond is most likely fake. Most real diamonds have imperfections called inclusions. There are diamonds out there that are sold flawlessly, but these diamonds are either very expensive or lab-created diamonds.
Test Using Black Light to Distinguish Real Diamond from Fake Diamond
For this test, you need a black light. Once you have your diamond in hand, turn off the lights in your location, and put the diamond in front of the black light. Most diamonds show blue fluorescence under black light and hence a blue color. The blue light means the diamond is real. If you do not see the blue color and instead see a slightly green, yellow, or gray fluorescence, this usually means the gem is fake. However, you should know that this test is not absolute and not all real diamonds will show a blue fluorescence.
Test Using a Loupe to Distinguish Real Diamond from Fake Diamond
Jewelers use a jeweler’s lens to see small details up close. A loupe and magnifying glass are therefore different. The difference between them is that the loupe does not have a handle and its lens frame is a bit more tapered. Jewelers often use magnifiers when examining diamonds for grade and clarity.
First, seek for inclusions using the loupe. Mined diamonds often have minor and natural defects that indicate the diamond is real. Next, check for minor mineral spots or color changes. If there are little color changes and spots on the diamond, then the diamond is most likely real. However, keep in mind that some diamonds are flawless. If there are no flaws, that does not necessarily mean you are dealing with a fake diamond. It means that there are excellent diamonds that are rarely found. Although most real diamonds often appear to have imperfections, this method is not very reliable in making the final decision.
