What is Moissanite?
What is Moissanite?
Moissanite is one of the most brilliant gemstones on earth — and it’s not a diamond. Originally discovered in a meteor crater in 1893 by scientist Henri Moissan, moissanite is now lab-created, making it an ethical and sustainable choice for fine jewelry.
How Does Moissanite Compare to Diamond?
Moissanite actually has a higher refractive index than diamond, meaning it produces more fire and brilliance — that rainbow sparkle you see in the light. Here’s a quick comparison:
- Hardness: Moissanite scores 9.25 on the Mohs scale (diamond is 10) — making it extremely durable for everyday wear
- Brilliance: Higher refractive index than diamond — more sparkle, more fire
- Color: Our stones are D Color (colorless) — the highest grade
- Clarity: VVS1 — virtually flawless to the naked eye
- Ethics: 100% lab-created — no mining, no conflict
- Price: A fraction of the cost of a comparable diamond
