Are Diamond Testers Accurate?

Anyone who loves jewelry knows that you can't put a price tag on your favorite gems. This is especially true if you have a set of diamond earrings or a diamond necklace. But if you've been tempted to test the authenticity of your jewelry, you may have wondered about the accuracy of the diamond testers on the market.

In this post, we take a look at diamond testers, how they work, as well as which ones to look for when shopping around.

Are Diamond Testers Reliable?

Diamond Testers are reliable and very accurate tools when it comes to checking the authenticity of a diamond. You can either use a thermal diamond tester or an electrically conductive tester.

However, a thermal diamond tester can prove to be faulty when presented with Moissanite! This is because Moissanite conducts heat at the same rate as diamond.

This should not worry you, though. The problem can be solved by using an electrical conductivity diamond tester. Even though diamond and Moissanite conduct heat at the same rate, the two gems conduct electricity differently.  

How Do Diamond Testers Work?

Diamond testers are centered on a very simple principle. They use the principle of conduction to tell you whether a stone is a diamond or not.

Diamond is the most thermally conductive material, with a rating of 2200W/(m.k). It's even five times more thermally conductive than silver and copper. A thermal conductive diamond tester works by passing heat through a diamond and examining how fast heat flows through the stone.

Even though diamond conducts heat at the same rate as Moissanite, Moissanite is an electric conductor, and diamond is not. This is the principle that electrical conductivity diamond testers use to differentiate Moissanite from diamond.

Different Types of Diamond Testers You Should Consider Purchasing

While there are different types of diamond testers in the market today, here are some that are worth your dime.

  • Electrical Conductivity Diamond Tester
  • Hardness Indenter Diamond Tester
  • Thermal Conductivity Diamond Tester
