Many people considering moissanite jewelry often ask the same question: Does moissanite pass a diamond tester?

Because moissanite looks very similar to a diamond, it can be difficult to tell the difference with the naked eye. In fact, moissanite is famous for its brilliance and fire, sometimes even appearing more sparkly than diamonds.

In this guide, we’ll explain how diamond testers work and why moissanite can often pass these tests.

⸻

How Does a Diamond Tester Work?

A diamond tester measures thermal conductivity, which is how well a gemstone conducts heat.

Diamonds conduct heat extremely well compared to most other gemstones. When a tester touches the stone, it measures how quickly heat moves through it.

If the stone conducts heat quickly, the tester may indicate that it is a diamond.

⸻

Does Moissanite Pass a Diamond Tester?

Yes, moissanite can pass a diamond tester.

This happens because moissanite also has very high thermal conductivity, similar to diamonds. As a result, many traditional diamond testers cannot distinguish between the two gemstones.

However, modern professional testers can often detect the difference using electrical conductivity testing.

Why Moissanite Is Often Mistaken for Diamond

Moissanite is one of the closest diamond alternatives because of its remarkable properties:

• Exceptional brilliance and sparkle
• High durability (9.25 on the Mohs scale)
• Strong thermal conductivity
• Colorless options similar to high-grade diamonds

Because of these qualities, moissanite jewelry is becoming increasingly popular around the world.
