Moissanite vs Diamond - What's the Difference?

The question often comes up. Moissanite looks like a diamond — but it's not a diamond. So what's the real difference? And why are more and more people choosing moissanite?

Origin

Diamonds form deep within the Earth over millions of years. Moissanite, on the other hand, has a wilder history — it was first discovered in a meteorite crater by chemist Henri Moissan in 1893. A stone literally from space. Today, moissanite is created in a laboratory, guaranteeing absolute purity and 100% ethical production — with no mining, no environmental impact.

Brilliance

This is where moissanite surprises. It has a refractive index of 2.65 — higher than that of diamond (2.42). In short: it captures light and reflects it with greater intensity. Under certain lighting conditions, moissanite shines brighter than a diamond. This is not a flaw — it's its signature.

Hardness

Diamond is the hardest material that exists — 10 on the Mohs scale. Moissanite reaches 9.25 — making it the second hardest stone in the world. In practice, it doesn't scratch with daily wear and retains its brilliance for decades.

Price

A one-carat VVS1 quality diamond costs between €5,000 and €15,000. A VVS1 moissanite of the same size costs a fraction of that price — without compromising on visual quality. That's why OMIRO chose moissanite: not to be cheaper, but to be just as good without the arrogance of the price.

What to remember

Moissanite is not a diamond imitation. It is a stone in its own right, with its own properties, its own history, and its own brilliance. For those who want a quality, ethical, and long-lasting piece — it's the obvious choice.

At OMIRO, every piece of jewelry is set with GRA-certified VVS1 moissanite, mounted on 925 sterling silver. A combination designed to shine effortlessly.
