Does Moissanite Pass a Diamond Tester? The Truth About Moissanite vs Diamonds

If you’ve ever shopped for moissanite jewelry, you may have wondered:

“Does moissanite pass a diamond tester?”

The short answer is:

👉 Yes — many moissanite stones will pass a standard diamond tester.

That surprises a lot of people because moissanite is technically not a diamond. However, moissanite shares several physical properties with diamonds, including high thermal conductivity, which is exactly what many diamond testers measure.

Today, moissanite has become one of the most popular diamond alternatives because it delivers incredible brilliance, durability, and luxury — without the extremely high price tag of natural diamonds.

If you're considering moissanite jewelry, here’s everything you should know.


What Is Moissanite?

Moissanite is a lab-created gemstone originally discovered in a meteor crater by scientist Henri Moissan.

Because natural moissanite is extremely rare, nearly all moissanite used in jewelry today is ethically lab-created.

Moissanite is loved for its:

  • Exceptional sparkle
  • Near-diamond appearance
  • Durability for everyday wear
  • Affordable luxury pricing

Why Does Moissanite Pass a Diamond Tester?

Most standard diamond testers work by measuring thermal conductivity.

Diamonds conduct heat extremely well.

So does moissanite.

Because both gemstones transfer heat similarly, many handheld testers identify moissanite as a diamond.

That’s why jewelers often use more advanced testing equipment to distinguish between:

  • Natural diamonds
  • Lab diamonds
  • Moissanite
