What Is a Diamond Tester?

A diamond tester is a small and portable device that can fit in your pocket. Despite its small size, this is a powerful device which can distinguish diamonds from all other minerals except moissanite. This device has a small tip which helps test the diamond. This device uses heat to observe if a diamond is real or fake.

How Does a Diamond Tester Work?

You should know that there are different types of diamond testers. The basic ones use heat-detection to test the diamond. There are also multi-testers which combine electrical conductivity as well as heat-detection to test the diamond.

When it comes to the basic diamond tester, the hear passes through the mineral and will reveal if it’s a diamond. Different minerals conduct heat in different ways and that is how the tests figures out if the diamond is a fake. The electrical testers use the same principal. There are better because they can also distinguish mineral moissanite.

How to Choose a Diamond Tester?

If you decided to purchase a diamond tester, there are a few things you should take into consideration. First of all, make sure that you purchase the diamond tester from a professional store or a trusted website. After that, take into consideration some of these features to purchase the best tester.

Electrical Conductivity

Look for a diamond tester which also uses electrical conductivity because it can also distinguish diamonds from moissanite. The testers which use only heat detection can’t tell apart moissanite from diamonds. Nowadays, you can find a lot of diamonds testers which combine electrical and heat testing.

Metal Detector

Another important feature a good diamond tester needs to have is a metal detector. Sometimes, the testers that don’t have metal detection can show that a diamond is real when you point to the metal part of the ring. If the tester has a metal detector and you point to the setting of the ring it is going to indicate that it is a metal and not a stone or a diamond.

Small Diamonds

You should also look for a tester that can determine the authenticity of small diamonds. For instance, there are certain models which can only test diamonds bigger than 0.05 carats. However, if you have smaller diamonds, you need a diamond tester that can also test them.

Are These Testers Reliable?

Unlike other diamond testing methods, a diamond tester is the most reliable. As we mentioned earlier, there are some models which only use heat detection so they won’t be able to see the difference between diamonds and moissanite. Also, the metal detection feature is a must, especially if you are testing diamonds which have been put on a piece of jewelry.

Also, the mechanism is simple to understand and the tester is easy to use, even by beginners. The tester uses heat and electrical conductivity to distinguish different minerals from real diamonds. When the diamond is real, the tester makes a sound and the LED lights go green. However, when the lights go red or the tester doesn’t make a sound it means that the diamonds are fake.

Having a diamond tester is a good investment that is going to save you a lot of money in the long run. These tiny instruments are reliable, easy to use, and very compact. Because of their small size, they can be used anywhere and they can be stored and moved without a problem. Most of these testers have budget-friendly price. However, some advanced models could cost up to $300.

Conclusion

These are some of the most important things you should consider before you purchase a diamond tester. Also, take into consideration your budget before you select the best device. Make sure to choose a tester that can also determine the authenticity of small diamonds.
