What Is a Moissanite Diamond? Is It Real?

If you’ve browsed engagement rings online or visited a jewellery showroom, you may have come across the term "moissanite diamond"—but what does it actually mean?

Is it a real diamond, or just a clever name for a fake?
Is moissanite even a real gemstone?

Let’s clarify the confusion. In this blog, we’ll explain exactly what moissanite is, why it’s sometimes called a “diamond,” and how it compares to both lab-grown and mined diamonds.

First Things First: Is Moissanite a Diamond?

No—moissanite is not a diamond.

It is a completely different gemstone, made of silicon carbide, not carbon.

However, it’s:

• Clear and colourless (like a diamond)

• Extremely sparkly and hard (like a diamond)

• Often cut in the same shapes and set in the same rings as diamonds

Because of these similarities, it’s sometimes referred to casually as a “moissanite diamond”—but that’s not technically accurate.

💡 Moissanite is real—but it’s not a real diamond.

Is Moissanite a Real Gemstone?

Yes—moissanite is absolutely a real, lab-grown gemstone.

• It was first discovered in 1893 by scientist Henri Moissan in a meteorite crater

• Natural moissanite is incredibly rare

• All jewellery-grade moissanite today is ethically lab-created

• It’s recognised by gemologists worldwide as a real, precious stone

Think of it as the modern, sustainable alternative to mined gems.

Why Do People Call It a “Moissanite Diamond”?

The term is sometimes used because:

• It looks like a diamond

• It’s cut like a diamond

• It’s used in engagement rings, just like diamonds

• It's a marketing shortcut to describe its similarity

But in professional and gemological terms, moissanite should not be called a diamond.

Calling it a “moissanite diamond” is like calling a white sapphire a diamond—it’s just not accurate, even if it sparkles similarly.

How Does Moissanite Compare to Real Diamonds?

Moissanite is an ethical, budget-friendly, and stunning option—but it’s not a diamond in composition or resale value.

Who Buys Moissanite—and Why?

At Diamond Lab, we work with clients across Australia who choose moissanite because:

• They want a bigger look for less

• They value sustainability and ethics

• They love the extra sparkle and fire

• They’re building a custom ring on a smart budget

• They prefer personal choice over tradition

Moissanite isn’t for everyone—but for the modern, intentional couple, it can be the perfect fit.

• A dazzling, long-lasting, and meaningful alternative to diamonds

But no—it is not a diamond, and shouldn’t be labelled as one.
