Moissanite vs Diamond: What's the Difference?
What is moissanite?
Moissanite is silicon carbide — a gemstone first discovered by Nobel Prize winner Henri Moissan in 1893 inside a meteor crater. Natural moissanite is so rare that virtually every stone on the market today is lab-created, which means consistent quality, zero mining, and a price that makes real ice accessible.
Side by side
| Moissanite | Diamond | |
|---|---|---|
| Hardness (Mohs) | 9.25–9.5 — second hardest gem worn in jewelry | 10 |
| Brilliance (refractive index) | 2.65–2.69 — more sparkle | 2.42 |
| Fire (dispersion) | 0.104 — over twice the rainbow flash | 0.044 |
| Clouds or fades over time? | Never | Never |
| Conflict-free guaranteed | Always — lab-created | Depends on origin |
| Price | A fraction of the cost | Premium markup |
Does moissanite pass a diamond tester?
Yes. Standard diamond testers measure thermal conductivity, and moissanite conducts heat like diamond — so it passes. (Dual testers that also measure electrical conductivity can identify a stone as moissanite, which is exactly what it is. We never sell moissanite as diamond — every listing states the stone type.)
Why we chose moissanite
More brilliance, more fire, nearly identical durability, none of the markup and none of the mining. You get a piece that floods with ice, passes the tester, and never clouds — for a price that doesn't require financing.
