What is Moissanite?

Moissanite is a natural and man-made mineral composed of silicon carbide. Its occurrence in nature is rare, found only in upper mantle rock and meteorites. It is often found as inclusions in diamonds, xenoliths, kimberlite, and lamproite. Moissanite has come a long way since its discovery over 120 years ago and is now lab-grown with minimal environmental impact due to its rarity. 

Its durability makes it perfect for a variety of cuts, giving jewelry designers numerous options for engagement rings and other jewelry settings. When looking for moissanite, remember to consider its brilliance and variety, which sets it apart from other jewelry gems. Seeing this stunning gem in person is an experience that cannot be matched, no matter what shape catches your eye.

What to Look For in a Moissanite Engagement Ring


The most obvious difference between moissanite and diamonds is their brilliance. Moissanite, which has similar cuts and shapes to diamonds has a high dispersion value, which creates a colorful rainbow-like effect when rotated. Diamonds reflect white light without the rainbow effect. Moissanite has inclusions like diamonds do.


When it comes to color, Moissanite used to have a yellowish or greenish tint, but manufacturers have improved the creation process, resulting in high-quality, colorless Moissanite. It is graded on a scale similar to diamonds.


For diamonds, carat weight refers to how heavy the stone is. However, moissanite is less dense than diamond which makes the two stones difficult to compare by weight. Due to the density difference, a moissanite’s “carat weight” is denoted by the stone’s size in millimeters. For example, a one-carat diamond is comparable to a 6.5mm moissanite.

What is the most important factor of moissanite?

Did you know that moissanite has a distinctive sparkle that can be enhanced through cutting? Depending on how it's cut, it can resemble a diamond or showcase its dazzling rainbow fire. Opting for a brilliant cut can bring out the most sparkle, just like with diamonds. However, since moissanite is naturally quite shiny, a brilliant cut can accentuate its unique fire and make it less diamond-like in appearance.

What settings and metals work best with moissanite?

Moissanite is a versatile gemstone that can be used in both modern and classic ring designs. Their wide range of colors make them a great match with your preferred metal color. The result is a stunning and unique engagement ring.

How durable is moissanite? Is it better than Cubic Zirconia?

Moissanite is incredibly durable and rank 9.5 on the Mohs hardness scale, just below diamonds. Because of this, moissanite is perfect for daily wear and can last a lifetime. Cubic zirconia is an 8.5, which isn't quite as good.

Can the average person tell the difference between cubic zirconia and moissanite?

The most sparkling of the two is moissanite. Despite being labeled 'colourless', moissanite always has a hint of gray or yellow, which makes it easier to distinguish. When moissanite sparkles, it resembles a disco ball. On the other hand, cubic zirconia is purposely designed to be completely colorless.

Can the average person tell the difference between moissanite and diamond?

Most people cannot tell the difference between moissanite and diamonds. Moissanite is naturally quite shiny, but a brilliant cut can accentuate its unique fire and make it less diamond-like in appearance.
