Moissanite vs Diamond: The Real Differences

Moissanite and diamond look almost identical on a hand — both colorless, both blazing with light. The differences are real but specific, and once you know them you can choose with confidence.

“Fire” is the colored light a stone throws — the flashes of rainbow you see when it catches the light. It's measured by dispersion, and moissanite's is 0.104 versus a diamond's 0.044. Its refractive index is higher too (2.65 vs 2.42).

In plain terms, moissanite throws more than twice the fire of a diamond. In bright light it can sparkle almost disco-bright. Most people love it; if you specifically want a diamond's subtler, icier sparkle, that's worth knowing up front.

On the Mohs scale, diamond is a 10 — the hardest natural material there is. Moissanite is 9.25, second only to diamond among the stones you'll find in jewelry, and well above sapphire.

For everyday rings, that means moissanite won't scratch, chip, or cloud with normal wear. It's a genuine forever stone.

This is the headline. A moissanite of the same size, color, and clarity costs a small fraction of a diamond — often a tenth or less. Because it's grown in a lab, there's no mine, no diamond supply chain, and no traditional markup. That's how every Airwaves piece stays under $200.

Our moissanite is D-color — the top, completely colorless grade — and eye-clean. Every stone is GRA certified, and the certificate ships in the box.

If you want maximum sparkle and value and you're happy with a lab-grown stone, moissanite is hard to beat. If a mined diamond's specific status matters to you, that's a personal call — but optically, most people can't tell them apart on a hand.
