Moissanite vs Diamond: What's the Difference? | ADEL Jewellery NZ

If you've been researching jewellery recently, you've probably come across moissanite. At first glance, moissanite and diamonds can look remarkably similar, but there are some important differences worth understanding before making a decision.

The good news? Neither is necessarily "better" than the other. The right choice comes down to your priorities, budget, and what matters most to you.

What is a Diamond?

Diamonds are formed naturally over millions of years beneath the Earth's surface and are prized for their durability, rarity, and history.

Diamonds are graded according to the well-known 4Cs: Cut, Colour, Clarity & Carat weight.

Because of their rarity and reputation, diamonds are often associated with luxury, milestones, and traditional fine jewellery.

What is Moissanite?

Moissanite is a gemstone originally discovered in a meteor crater by French scientist Henri Moissan.

Natural moissanite is incredibly rare, so the stones used in jewellery today are lab-created. This allows jewellers to produce beautiful, high-quality stones while keeping prices significantly lower than natural diamonds.

Moissanite has become increasingly popular in recent years thanks to its durability, brilliance, and value.

Which Sparkles More?

One of the biggest differences between moissanite and diamonds is how they reflect light.

Diamonds are known for their crisp white sparkle.

Moissanite reflects both white light and colourful flashes of rainbow light, often appearing more brilliant than a diamond under certain lighting conditions.

Some people love the extra sparkle, while others prefer the more subtle appearance of a traditional diamond.

Durability for Everyday Wear

Both stones are suitable for daily wear.

On the Mohs Hardness Scale:

  • Diamond: 10/10

  • Moissanite: 9.25/10

This makes moissanite one of the hardest gemstones available, second only to diamond.

For earrings, necklaces, and everyday jewellery, both offer excellent durability when properly cared for.

Appearance

To the average person, moissanite and diamonds look extremely similar.

In fact, many people would struggle to tell the difference without specialised equipment.

The main visual difference is that moissanite tends to display more colourful flashes of light, while diamonds typically appear slightly more subdued and white in their brilliance.

Price

Price is often where the biggest difference becomes apparent.

A moissanite stone of comparable size can cost significantly less than a natural diamond.

This allows buyers to choose a larger stone or invest in quality jewellery without the premium price often associated with diamonds.

For many people, moissanite offers an attractive balance between beauty, durability, and affordability.

Which Should You Choose?

It's really up to you and your own preference.
Choose a diamond if:

  • You value natural rarity.

  • You prefer a traditional gemstone.

  • The history and prestige of diamonds are important to you.

Choose moissanite if:

  • You love exceptional sparkle.

  • You want excellent durability.

  • You are looking for strong value without compromising on appearance.

Final Thoughts

Both moissanite and diamonds are beautiful choices.
