Working Principle of Diamond Testers

As the name suggests, the diamond tester is a device to check whether a gemstone is a diamond or not. This device is one of the indispensable pieces of equipment for those dealing with gemstone works and for jewelers who buy and sell precious jewelry. With their functionality and speed, they provide great convenience to jewelers and those who are interested in the jewelry business and save time.

How to Test a Diamond

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 a 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.

Diamond testers have a fine-tipped part. This fine-tipped part gives specific signals when the stones to be tested are touched, analyzing whether the diamonds are real or fake. During the measurement, it not only decides whether the stone is a diamond but also measures the size of the stone. These signals can be audible warning or colored LED lights. LED lights in these devices usually have red, yellow, and green lights as a warning color signal. These lights are placed in different color levels. Users using this device can have information about whether the stone is a diamond or not and its size according to the level of the lights. When the tip of the device touches the stone, the led lights start to light. These lights provide information to the user about the size of the stone according to its colors.

Diamond test devices have a small margin of error, but this margin of error may vary depending on the quality, brand, and features of the device. At the same time, if a different object is controlled instead of a diamond, it also warns the user by deciding whether your device has been touched to the right place or not.

When you touch the diamond surface with the diamond tester, the LED lights on the device. You can see the number corresponding to the hardness level of the diamond here. This information is correct. This shows the corresponding number on the hardness scale, also called the Mohs scale.

What are the Features of Diamond Testers?

Among the features of diamond testers, the ability to measure stone sizes with small-scale precision, and to convert the dimensions they measure into black. Some have thermoelectric tips that can be pushed for precision measurement. The more advanced ones can be connected to the computer with USB or different computer access cables and can be adjusted with computer support. The dimensions of the devices vary according to their features, but they are generally light and small enough to be carried by hand. With these features, they are very useful and useful. Although it has small margins of error, it gives correct results when considered as a general whole.

How To Use A Diamond Tester

Using a diamond tester is very easy. There are simple steps you need to follow. You can get results very quickly and very easily. You need to follow the instructions carefully in order to get the correct interpretations. There are a couple of tips that you need to keep in mind that.

  • The gemstone or diamond should be cleaned completely before using a diamond tester
  • There is no need to push the diamond tester very hard. It may damage your stone or directly break it.
  • You need to press the device at a 90-degree angle.
  • If there is a metal frame on your stone, you need to be careful about not touching the metal with the tip of the device. If it touches, it gives an inaccurate result.
  • If your stone is loose stone, it is better to use a neural testing base.

Conventional and New Design Diamond Testers

A diamond tester of several years does not match the variety of today’s diamond simulators and synthetics because these simulators have all the chemical properties of a real diamond. A traditional diamond tester has a metal tip that is heated and then applied to the cooler surface of a diamond. Heat transfer occurs and the readback between handsaw and handsaw is a match, as the heated end of the tester also heats the apple. This shows that the stone is really a diamond.

However, today’s simulators can mimic a pretty convincing diamond. Recently produced diamond testers use a mild to a very different logic to compare the physical properties of diamonds and simulators, and these other diamond testers work to find other unique diamond properties that are unique in today’s simulators and synthetics.

GIA (Gemology Institute of America) Diamond Pen

The GIA initiated the design of a tool that works on a different diamond feature to differentiate them less from the real type. Diamonds express a certain affinity for oil and oily liquids, according to the GIA. The Institute has developed a tool called the Diamond Pen. A pen of construction such as a fountain pen contains a certain type of oily liquid that leaves visible marks on otherwise smooth, non-absorbent diamond surfaces. However, when another stone is tried on its facet, the liquid inside is collected without separating.

Moissanite Tester

Moissanite is a natural stone. It does not exist in nature in a form that can be cut into precious stones. This stone was invented in the 1990s. Another remarkable detail about moissanite is that it is tested as a “diamond” in diamond testers. Therefore, if you have a standard diamond tester, you also need a moissanite tester. Because diamond testers accept these stones like diamonds.

What is Moissanite Tester?

Moissanite is a mineral known as silicon carbide that occurs naturally in the world. It has an even brighter appearance than all existing and known stones. This stone was discovered in 1893 by the French scientist Dr. Henri Moissan. It is also called moissanite in his memory. In addition, moissanite is one of the hardest stones after diamond.

It is quite difficult to distinguish moissanite from the diamond. Having a moissanite tester is an important detail in distinguishing this stone since it is tested as a diamond in testers. Presidium devices are used extensively to distinguish moissanite from a diamond. Thanks to this device, diamond, and moissanite can be easily distinguished from each other. However, this device cannot distinguish synthetic diamonds produced in the laboratory. These testers directly measure the electrical conductivity of the gemstones and check whether the gemstone is an original diamond or moissanite. Moissanite tester models and prices, which are practical and provide ease of use, vary.

How to Use a Moissanite Tester

The easiest way to test moissanite is, of course, using a moissanite tester. The moissanite tester puts an electric current in the gemstone and then measures how well the stone conducts electricity compared to a diamond. This method is very fast and practical, especially if you are measuring more than one stone at a time. In order to use it, you must first turn on your device and touch the thin end of the device to the stone or the stone in the jewelry you want to measure. Afterward, you can easily test whether the stone is a diamond or moissanite from the warning screen of the device by pressing the test measurement button.

What Does the Moissanite Tester Do?

As we have mentioned above, this device allows the moissanite to be easily distinguished from a real diamond. These devices provide consistent and reliable results every time. There is no waiting period between the tests performed. In addition, these test devices have a clear and visible display for easy reading. The test devices, which are very easy to use and practical, are very light.

Are Diamond/Moissanite Testers Reliable?

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 the 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 charge 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. In this case, it is important to purchase the latest models. You can easily make sure whether or not it is a real diamond. It gives you the most accurate and most reliable results.
