Are Diamond Testers Accurate? How Do They Work? (Recommended Products)


Finding out if the diamond you own is real or fake is an overwhelming request. Are you sure you really want to know? Most curious people go to a jeweler to get the diamond tested. But you don’t have to be Sherlock Holmes to distinguish between real and fake diamonds. There are different diamond testers you can use. Using diamond testers is one of the most accurate ways to understand whether it is fake or real. 

By time technology has been developed very fast. With these technological advances even though it is easy to make fake diamonds, it is easy to differentiate whether or not it is real. Diamond testers are one of these most reliable ways. That’s why it is important to use the latest models. With the help of the latest technology, it becomes easier to detect. You can get accurate results easily. Thanks to its handy design, it is even easier than you thought. 

There are many options available to choose from. You can choose the one that fits your budget. Being the latest technology does not mean that it needs to be expensive. It is easy to find the proper one for yourself. 



Diamond testers are the simplest and the most effective way to understand whether your jewelry is fake or real. You do not need to purchase expensive ones. Even the cheaper ones work with the same mechanism. And, the expensive ones detect more details that you do not need to know. It is a good way to differentiate the diamonds because without taking your jewelry to the jewel, diamond testers give you an opportunity to learn at home by yourself. 

These diamond testers are called thermal conductivity probe as well. Its working mechanism is based on thermal activity. With the help of this tool, you can specify the thermal conductivity. Due to the feature of the diamond, you can understand if the heat increases slower, it means that it is not real. Because diamond is heat conductors. Thus, when you use a diamond test, it should not affect that much if it is a real diamond. If you realize that heat increases very fast, you can say that it is a fake diamond. 

Testing your diamond with a diamond tester is an easy process. It takes about 30 seconds to test. You need to follow the instructions and you learn easily the result. It is a good way to differentiate diamond and moissanite. If your precious stone passes the test, it means that it is a real diamond. 

A diamond tester is a small device that you can carry and store easily. It is a portable device. It has a small rectangular body with a small needle on top. It warns you with a beeping sound or by showing the result on its small screen. You get the results easily. 



With the help of the needle on top of the device, you can understand whether your diamond is fake or real. This needle works based on thermal connectivity. In order to use this diamond tester, basically, you need to place the needle on top of the top of your diamond. In this way, it is easy to get an accurate result. You just need to wait for a while. When you hear the beep sound or depending on the device it shows on its screen, it means that it is done. 

It means that the thermal connectivity level is determined. If the level increases very fast, the results show that it is positive. It means it is not real. The device alerts you in this situation. Even though it depends on the device you have, you can see the fluctuation of the thermal level on its screen while the device testing the results. 

As we mentioned above, the way the device shows positivity depending on the machine you have. If your diamond tester gives a positive result, it shows a “+” symbol on its screen or it alerts you by beeping sound. It is not a time-consuming process at all. This process is completed within seconds. 

How A Diamond Tester Works 


Heat conductivity is the principle of these diamond testers. They work based on this principle. They differentiate the heat difference. Heat passes through a diamond differently and this device detects it. It detects the rate of how the heat moves through the diamond. Thus, it gives you the result of whether it is a fake or real diamond. Keep in mind that in addition to heat conductivity, some devices include electrical conductivity. Those machines with electrical conductivity work based on the same principle as well. The only difference is instead of heat they use electricity. 



How Reliable/Accurate Are Diamond Testers? 


There is no need to worry about diamond testers’ accuracy level. They are very accurate. Even more, using a diamond tester is the most accurate way to understand whether the diamond is fake or real. Even though these machines are mostly used at home, many jewelers use this small device before buying and selling diamonds as well. 

There are many different diamond testers available in different brands. Some of them may give inaccurate results. That’s why it is important to choose a quality brand device. Because of the fact that there is moissanite on the market. Moissanite is a very similar gemstone to diamond and some devices make mistake to tell which one is diamond and which one is moissanite. As you can understand, moissanite is not real. It is important to make this difference. And investing in a good machine is the easiest way of it. You can get the results within seconds. 

In order to get the most accurate results, it is recommended to buy a diamond tester with electrical conductivity as well as thermal connectivity. Because of the fact that there is an electrical charges difference between diamond and moissanite. With the proper device, you can make this difference. 

The latest models have both of these features which are thermal conductivity and electrical conductivity. They are designed based on those.
