Moissanite vs. Diamond: What’s the Real Difference?

At Kronjuvel, we’re proudly diamond-free — by choice. Our jewellery features moissanite, a modern alternative that offers more sparkle, less environmental impact, and a fresh take on luxury.

But what exactly sets moissanite apart from diamonds? Let’s break it down.

Sparkle: More Fire, More Brilliance

Moissanite is known for its exceptional sparkle. In fact, it reflects light differently from diamonds — producing more "fire" (rainbow-coloured flashes).

Moissanite brilliance index: ~2.65
Diamond brilliance index: ~2.42

Result: Moissanite sparkles more — especially in sunlight or under spotlights.

Origin: Ethical & Lab-Created

All moissanite is lab-created, making it a conflict-free, sustainable choice.

Moissanite: Created in labs — no mining, no human cost
Diamond: Often mined (even lab diamonds require high energy processes)

Result: Moissanite is the go-to for conscious luxury.

Price: Significantly More Affordable

Moissanite gives you the luxe look — without the diamond markup.

Moissanite: ~90% less expensive than diamonds of similar size
Diamond: Price increases sharply with carat size and clarity

Result: You can size up or save — without compromising beauty.

Durability: Nearly as Hard as Diamond

Moissanite is incredibly durable — perfect for everyday wear.

Moissanite hardness: 9.25 on the Mohs scale
Diamond hardness: 10 on the Mohs scale (hardest natural material)

Result: Moissanite is tough enough for engagement rings, yet more forgiving on your budget.

Appearance: Subtle Differences

To the untrained eye, moissanite and diamond look very similar. Moissanite may display a touch more rainbow sparkle under certain lighting, while diamonds have a whiter, steely brilliance.

Result: Most people can’t tell the difference — and moissanite's fire is often preferred for its brilliance.
