If you're shopping for moissanite jewellery Australia and wondering whether it'll pass a diamond tester, you're asking exactly the right question. It's one of the most common concerns we hear from customers considering moissanite as an ethical and affordable alternative to diamonds. Let's break down what actually happens when you test moissanite with a diamond tester.
Why Moissanite Often Registers as Diamond on Basic Testers
Here's the thing: many basic thermal diamond testers will actually register moissanite as diamond. Sounds confusing, right? It happens because these simple testers work by measuring how quickly heat moves through a stone. Since moissanite conducts heat in a similar way to diamonds, a basic thermal tester can't tell the difference between them.
This doesn't mean your moissanite is secretly a diamond, though. It just means that particular testing method has limitations. Think of it like using a basic thermometer to identify different metals—it'll tell you temperature, but not what the metal actually is.
The Difference Between Basic and Advanced Testers
This is where things get really important. A basic thermal diamond tester is designed to separate diamonds from other common gemstones like cubic zirconia. But it wasn't specifically designed to distinguish between diamonds and moissanite, since moissanite wasn't widely used in jewellery until more recently.
A proper moissanite diamond tester—sometimes called a multi-tester—can actually tell the difference. These advanced devices measure additional properties beyond just thermal conductivity, allowing jewellers to accurately identify whether a stone is diamond or moissanite.
Why Cubic Zirconia Behaves Differently
Cubic zirconia, another popular diamond alternative, typically fails basic thermal diamond testers because it conducts heat differently. So if you're comparing options, that's one way basic testing can help narrow things down.
The Bottom Line
Does moissanite pass a diamond tester? Often yes, on basic thermal testers. But passing a basic test doesn't definitively prove what a stone is. That's why it's crucial to buy from reputable sellers who provide certification and transparency about their gemstones.
