Moissanite vs Diamond: Which One Should You Choose?

When shopping for a sparkling ring, necklace, or pair of earrings, one question often comes up: Should you choose moissanite or a diamond?

Although both gemstones offer exceptional brilliance, they differ significantly in composition, price, durability, and environmental impact.

In this guide, we'll explain everything you need to know to help you make the right choice.

What Is Moissanite?

Moissanite is a gemstone made from silicon carbide. Originally discovered in a meteor crater, it is now created in laboratories, ensuring consistent quality while reducing environmental impact.

Thanks to its unique composition, moissanite offers remarkable brilliance and is an excellent alternative to diamonds.

What Is a Diamond?

A diamond is a natural (or lab-grown) gemstone composed entirely of carbon.

Renowned as the hardest natural material on Earth, diamonds have long been associated with engagement rings and fine jewellery.

Natural diamonds form over billions of years under extreme pressure deep within the Earth.

The Main Differences Between Moissanite and Diamond

1. Brilliance

The most noticeable difference is their sparkle.

Moissanite has a higher refractive index than a diamond, allowing it to reflect more light and produce more colourful rainbow flashes.

Diamonds, on the other hand, offer a whiter, more subtle brilliance that many people consider timeless and classic.

If you love maximum sparkle, moissanite is an excellent choice.

2. Hardness

Hardness is measured using the Mohs scale.

• Diamond: 10/10
• Moissanite: 9.25/10

While diamonds remain the hardest gemstone available, moissanite is still exceptionally durable and perfectly suited for everyday wear.

3. Price

One of the biggest differences is cost.

Moissanite is generally much more affordable than a diamond of the same size.

This allows you to enjoy a larger, brilliantly sparkling stone while staying within your budget.

4. Origin

Most moissanites are created in laboratories.

Diamonds are available as:

• Natural diamonds
• Lab-grown diamonds

Lab-created gemstones generally have a lower environmental impact than traditionally mined diamonds.

5. Care and Maintenance

The good news is that both gemstones require very little maintenance.

Simply clean them with warm water, mild soap, and a soft brush to keep them looking their best.
