Moissanite is a gemstone that Henry Moissan discovered in 1893. He found all the particles in the gem. As a result, scientists named moissanite after him.

During his discovery, Henry Moissan thought he had discovered diamonds. However, he later found that moissanite had silicon carbide, unlike diamonds that have carbon ions.

While natural moissanite is hard to find, it is possible to create it in the Lab. After all, experts create all the particles in the Lab.

If you fancy expensive jewelry and can’t afford diamond-made ones, moissanite products may suit you best. You’ll appreciate the fact that it has almost the same illusion and appearance as a diamond.

What are the benefits of moissanite?

Moissanite is a good substitute for diamond. However, it comes with additional benefits. Here are some that will undoubtedly excite you:

Both moissanite and lab diamonds can replace natural diamonds. However, that doesn’t make them the same. Below are some of the differences you should know about the two.


If you didn’t know, experts refer to sparkle as dispersion. In our case, sparkle distinguishes lab diamond and moissanite. Moissanite has a dispersion rate of 0.104. On the other hand, diamond has a dispersion rate of 0.044. Thus, we can say that moissanite reflects more light than a lab diamond.


Color is another feature you can use to differentiate moissanite and lad diamond. Lab diamonds are available in almost all colors.  Also, you can still find colorless ones.

On the contrary, natural moissanite is available in three colors. Colorless and almost colorless are among the colors available. You can also find the one with yellow and green shades.

Nonetheless,   with the coming of technology, experts can make colored moissanite. It’s imperative to note that traditional moissanite had a yellowish color.


Lab diamond and moissanite can break and bend light apart in different ways. So, refraction is a critical factor that determines how a gem appears in your eyes.

Moissanite is doubly refractive.  As a result, all facets appear double if you look at them keenly.  Sapphire and tourmaline are other gems with double refraction.

Lab diamond, on the other hand, is singly refractive. Hence you wouldn’t see the facets as double. However, you must look at the gems at a particular angle for you to note this feature.


Diamond is the most rigid material you will ever see. On a scale of one to 10, scientists rank diamond at 10. Lab diamonds are not different on hardness either.

Moissanite, on the other hand, is a little bit softer. On the hardness scale, moissanite is at 9.25.  You would notice that this a little bit lower compared to lab diamond’s hardness.


Price is another factor that we can’t ignore about these gems. Lab diamonds are a little expensive as natural ones. Hence, if you need some, you might have to dig deeper into your pockets.

Moissanite is cheaper compared to lab diamonds. However, it is a perfect replacement for diamonds if you’re short of finances. Its hardness and sparkle give you value for your money.
