How Does a Moissanite Diamond Tester Work?

If you want to find out if your jewelry is moissanite or diamond, you should know how a diamond tester works. There are different testers that use science in different ways. Understanding how each tester works helps you make good choices when testing diamonds.
Thermal Conductivity Testers
Thermal conductivity testers check how fast heat moves through a gemstone. Here is what happens:
-
The tester has a hot metal tip that touches the stone.
-
It measures how quickly the heat spreads in the gem.
-
Diamonds move heat very fast because of their special properties.
-
The tester compares the heat loss to what is normal for diamonds and other stones.
Moissanite also moves heat quickly, so a simple diamond tester might say your moissanite is a diamond. This can make things confusing when you test your stone. You should remember that thermal testers are not always right for moissanite.
Electrical Conductivity Testers
Electrical conductivity testers use a different way to test. They check how well a gemstone lets electricity pass through it. Most moissanite stones let electricity flow, but diamonds usually do not. Some rare diamonds, called Type II, can let electricity pass, which makes testing harder. Tools like the Presidium Moissanite Tester II use this method to help you tell moissanite from diamond.
Combination Testers
Many jewelers use combination testers, also called multi-testers. These tools check both heat and electricity. This helps you get better results when testing diamonds. Some advanced multi-testers, like the GemTrue V3, are simple to use and give fast answers. Even with these tools, it can still be hard to tell moissanite from diamond because they are so much alike. For the best results, you should use more than one way to test or ask a professional for help.
Tip: If you want the best diamond testing, use a multi-tester and ask a jeweler for help if you are not sure.
Pass a Diamond Tester: Moissanite Explained

Why Moissanite Can Pass Diamond Tester
You might wonder why moissanite can pass a diamond tester. The reason is because moissanite and diamond are a lot alike. They share some of the same physical traits. This makes it hard for a diamond tester to tell them apart. Most testers check how heat or electricity moves through a stone. Both moissanite and diamond move heat very fast.
