Does Moissanite Pass a Diamond Tester?
The main inquiry which arises repeatedly during your search for moissanite jewelry or your online sale of it exists as follows:
Does moissanite pass a diamond tester?
The short answer is YES — most standard diamond testers will show moissanite as “diamond.”
The explanation for the answer needs to be understood because it holds greater significance than the initial response. we’ll break down how diamond testers work, why moissanite fools them, and how moissanite compares to diamonds diamond, visuals, and expert insights.
What Is a Diamond Tester?
The diamond tester operates as a portable instrument which determines gemstone identity through its ability to measure thermal conductivity and electrical conductivity.
How Diamond Testers Work
- The probe sends heat into the stone
- The system measures the speed at which heat moves through the material
- Diamonds conduct heat with extreme efficiency
- The tester indicates a diamond when heat moves through the material at high speed
Key Point:
The diamond testers measure conductivity of gemstones but they do not measure their rarity or their origin or their market value.
Why Moissanite Passes a Diamond Tester?
The upcoming section contains its most engaging material.
Moissanite Has High Thermal Conductivity
The heat conductivity of Moissanite approaches that of diamond because:
- Standard diamond testers cannot tell them apart
- Moissanite often registers as "diamond"
- Even jewelers must use advanced tools
Bold Truth:
Moissanite is the only gemstone that consistently passes a diamond tester.
Does Moissanite Always Test as Diamond?
Basic Diamond Testers
- YES — Moissanite passes
- The test results show "Diamond"
- Causes confusion for buyers
On Dual Diamond–Moissanite Testers
- SOMETIMES — depends on quality
- The system evaluates both thermal and electrical conductivity
- Testers may misidentify high-quality moissanite due to its properties
On Professional Lab Equipment
NO, advanced tools can identify moissanite accuratelyThe statement because expert instruments can detect moissanite through their specialized capabilities.

Why Jewelers Love Moissanite
Moissanite isn’t just a diamond alternative — it’s a smart luxury choice.
Top Reasons
- Looks like diamond
- Passes diamond testers
- More fire & sparkle
- Affordable luxury
- Eco-friendly & ethical
- Durable for daily wear
Can a Diamond Tester Tell Real Diamond from Moissanite?
Simple Answer: NO
Diamond testers:
- Cannot detect chemical composition
- Cannot measure refractive index
- Cannot judge value or authenticity
Tools That CAN Tell the Difference
- Moissanite-specific testers
- Electrical conductivity meters
- Professional gemological microscopes
- Lab certification (GIA / IGI)
Is Moissanite “Fake”? Let’s Clear the Myth
- Moissanite is NOT fake
- It is NOT cubic zirconia (CZ)
- It is NOT glass
- Moissanite is a real gemstone
- Made from silicon carbide
- Has its own brilliance & identity
Final Verdict: Does Moissanite Pass a Diamond Tester?
- Most diamond testers successfully detect moissanite as a gemstone.
- The material exhibits all diamond characteristics through its visual appearance and sparkling features and operational capabilities.
- Only advanced tools can tell the difference
- The product delivers three benefits which include ethical standards and affordable pricing and luxurious qualities.
Moissanite has become a revolutionary force in the jewelry market because it serves as an alternative to traditional gemstones.
