Forever One Moissanite

We introduced moissanite to the world nearly 30 years ago.

Moissanite is so rare in nature that it must be made in order to produce fine jewelry gemstones. Our ability to create the first-ever lab created moissanite gemstones revolutionized the industry and set a new standard for brilliant, colorless gems.

Not all moissanite is created equal!

From small artisans to the largest jewelry retailers - moissanite has become a popular choice as an alternative to traditional mined diamonds. But it’s not all created equal!

Forever One™ Moissanite is created with our original patented process and hand-cut by master cutters using our proprietary techniques. We’ve set the standard for moissanite since 1995 and in those three decades of production, we’ve perfected the process! With our Signature engraving on the girdle of all stones 4mm and larger, you can be confident that only our moissanite is the World’s Most Brilliant Gem™.

What is moissanite?

Moissanite is a gemstone born from the stars. It was first discovered in 1893 by a French scientist named Henri Moissan, who later won the Nobel Prize in Chemistry. He discovered particles of the gem that would eventually bear his name in Arizona, in a crater created by a meteorite that fell to Earth. He initially thought that he had found diamonds, but later determined that the crystals were composed of silicon carbide.

Natural moissanite is incredibly rare, so moissanite available today is laboratory-created. After many years of trial and error, the particles Moissan discovered were successfully synthesized to produce what is now one of the world’s most scintillating gemstones.

Moissanite is engineered to appear very similar to diamonds but is compositionally and visually quite different. The durability, brilliance, and fire of the two gems are quite distinct but are both very good thermal conductors.


Moissanite is extremely durable, tough, and second only to diamond in its resistance to scratching and abrasion. It scores a 9.25 on the Mohs Hardness scale.


The most dominant feature of moissanite is its brilliance. When we refer to the brilliance of moissanite, we’re also referring to its sparkle. Known for its high refractive index of 2.65, moissanite is quantifiably the most brilliant gemstone on earth!

Fire (Dispersion)

One of the most distinguishable elements of a moissanite gemstone is its fire or dispersion. Dispersion is caused as light radiates through the gemstone on different wavelengths—each wavelength produces beautiful flashes of color throughout the gemstone.
