The Brilliant Diamond Alternative

Shop The Collection


Moissanite isn’t an artificial diamond.

Diamond is composed of pure carbon, while moissanite is made of silicon carbide. These two gems look similar, and moissanite shares many of the diamond’s best traits (like extreme toughness and clarity) but there are areas where moissanite shines brighter than its famous cousin.

The ABC's of Moissanite


Moissanite is nearly identical to both lab-grown and earth-mined diamonds, but is available at a far more affordable price point.



Moissanite has a higher refractive index than diamond, and it exhibits nearly twice as much fire under direct light.



Our moissanite is made in an environmentally and ethically responsible lab, so you can be sure your gem is 100% sustainably sourced and conflict-free.

Frequently Asked Questions
What is Moissanite?

A moissanite is a lab-created gemstone, known best as an alternative for diamonds. Moissanites are made of silicon carbide, and have a hardness and light-refracting characteristic that is very similar to a diamond.

Is Moissanite a brand of diamond or a simulated diamond?

Moissanites are NOT simulated diamonds. Diamonds are made of a carbon crystal, while moissanites are silicon carbide. Moissanites are lab-created gemstones that have a hardness and light-refracting characteristic that is very similar to a diamond.

Will Moissanite fade or change color over time?

No. Should brilliance, fire or color tone ever change, bring your moissanite to Icing On The Ring to have it replaced under Charles & Colvard's Limited Lifetime Warranty.

How strong is the Moissanite gem?

Moissanites have a hardness that is 95% as hard as a diamond, making them highly suitable for daily wear, engagement ring and anniversary ring applications.

WIll a Moissanite gemstone ever lose its fire?

No. Charles & Colvard provides a Limited Lifetime Warranty which guarantees that every Charles & Colvard created moissanite gemstone will maintain its fire and brilliance forever.

Why is Moissanite sold by millimeter rather than by scale?

Although the value of precious gemstones is partly based on their weight, this valuation method does not apply to moissanites. Because moissanites are lab-created, rarity-based valuations no longer apply. Instead, value is based on the cost of technology and energy consumption required to grow the moissanite crystal.

Is Moissanite graded on the GIA diamond color grading scale?

Because moissanites are not diamonds, GIA diamond grading scales do not apply. However, Charles & Colvard produces 2 color classes of moissanites, - Forever One Colorless and Forever Brilliant Near Colorless. Forever One resembles D-F color diamonds, and is suitable for platinum and white gold jewelry; while Forever Brilliant resembles H-J color diamonds, and is best for yellow or rose gold jewelry.

The Moissanite Story

Approximately 50,000 years ago, a massive meteorite struck the Earth in what is now the desert of Arizona. In 1893, French chemist Henri Moissan was studying fragments of that meteorite when he discovered something peculiar...

What Henri initially mistook for a diamond was actually a new mineral, composed of silicon carbide. It was named Moissanite after its discoverer.


Naturally occurring moissanite is extraordinarily rare. Fortunately, over 100 years after its discovery, researchers perfected a process for creating moissanite in a laboratory setting. Today, it’s possible to purchase beautiful moissanite, one of the galaxy’s most fascinating gems - affordably, and under the guidance of jewelry professionals.
