Moissanite is said to be born from the stars. Basically, these natural crystals are made of silicon carbide and are created in the laboratory. The microscopic particles were also found in a crater in Arizona.

As natural moissanite is extremely rare, lab-created ones are very common. These gemstones are finally brought to their best form after many years of fine processing to make them as perfect as diamonds. Round-cut moissanite is the closest imitator of mined diamonds.

Moissanites still don't look exactly like real diamonds, as they are visually and compositionally distinct. I will explain in more detail how the difference is detected. These gemstones are even rarer than diamonds as they are found in very small quantities on Earth.

Moissanite is often used as an alternative to diamond in jewelry. It is especially popular as stones for engagement rings.

Diamond Nexus and Moissanite are excellent imitators of natural diamonds. The best part about both is that they fit the bill for most people.

If you have ethical and environmental concerns but love jewelry, these gemstones are the best choice for you!

However, when comparing the two, you will learn how the chemistry, brightness, price, durability and colors of the two gemstones are quite different.

I've tried to cover all the important features of these stones so you can be sure you have the right one in your hands!

Prices and accessibility

Diamond Nexus is a cheaper option compared to moissanite. Choosing any of them depends on the budget you have allocated for them.

As they are even rarer than diamonds, they can be expensive. Moissanite is usually 40% cheaper compared to a real diamond. 1 carat of this rare gemstone can cost up to $600 USD. The cost also varies according to the quality of the stone, ie; premium or super premium.

diamond nexus

Diamond Nexus is much cheaper compared to moissanite. You can probably get a nexus diamond for under $25. Prices vary by cut, color clarity, and stone size.

Colors and Clarity

This is of the utmost importance, as if you need a stone that resembles a diamond, you need to be very interested in the colors and clarity of the gem.


Although moissanite is usually labeled colorless, this gemstone casts gray and yellow tones in certain lighting environments. You can see better, lighter shades in larger sized moissanite.

Pure white moissanite and lightly colored gemstones are also commonly available in the market.

The highest quality moissanite is the clearest. Most moissanites sold have an exceptional level of clarity, however violations can still be found at the microscopic level.

diamond nexus

Diamond Nexus (lab-grown diamonds) are also available in clear and brilliant shades; however, like moissanite, you will also find dyed ones. Since Diamond Nexus are the closest imitators of mined diamonds, they are classified as (D), which means they are completely colorless.


Refraction is the key to any stone's brilliance. Diamond and its alternatives are also classified based on the amount of light they refract. Refraction simply means how much light is absorbed and reflected.

Both Diamond Nexus and Moissanite are at peak brightness, but still have notable differences.

diamond nexus

This diamond simulator shows white flicker and the refraction quality is excellent. In addition, these simulators are ideally cut for maximum refraction.

To make it look similar, the light that enters this stone is reflected entirely internally, contributing to its high refractive index, just like natural diamonds. Diamond Nexus shines brightly due to this high refractive index.

Because it is doubly refracted, moissanite scintillation is multicolored. As natural light hits this gemstone, you may notice shades of gray, yellow, and even red. It has a partially low refractive index and is not as bright as the Diamond Nexus.


Here we will talk about which of the two is easy to get and has a better reputation.


Moissanite is a much rarer stone compared to Diamond Nexus which is a lab developed simulator. Therefore, the demand for a moissanite engagement ring is much higher. Currently, however, this gemstone is not available very often and easily, although you can find a limited variety in many stores.

However, the downside is that tarnished stones can fade over time, as reported by some customers.

diamond nexus

Although Diamond Nexus guarantees the durability of these stones, customers still complain about their quality. Since they are man-made, they are more feasibly available and their affordability makes them a favorite for anyone looking for a diamond alternative.


Both stones are hard enough to be good diamond alternatives, however, there is still a significant difference between the two!

The best way to find out the hardness of a stone according to gemologists is the Moh scale. I've talked about this scale before and by now you should be familiar with the fact that this scale is the benchmark for measuring hardness.

Moissanite ranks at 9.5 when it comes to hardness. This means they can easily withstand high pressure and won't scratch the surface no matter what material they're hit with.

diamond nexus

On the Moh scale, the hardness level of this stone is 9.2. This does not mean that this stone is weak, however, it is not as hard as moissanite. Therefore, it is more likely to be scratched. It looks a lot like a mined diamond, but when it comes to the hardness level, there is an obvious difference between the two.


Hardness is not the same as tenacity. The hardness of a gemstone refers to how much external pressure it can withstand.


Moissanite is exceptionally strong and will not chip or break no matter how much pressure it has to withstand. Obviously not to be compared with the hardness of a diamond, but moissanite is arguably a close second!

diamond nexus

Yes, Diamond Nexus is also resistant, but compared to moissanite, it cannot withstand very high pressures or temperatures. It is more prone to chipping and breaking unless handled with care.

Common questions

Can I iron my moissanite like a diamond?

To be honest, I wouldn't pass any of them off as diamonds because these aren't real diamonds after all.
But yes, moissanite can be considered a diamond as it has almost the same brilliance and brilliance as mined diamond. In fact, moissanite is the only gemstone that can truly pass for a diamond due to its hardness and durability.

Can you tell the difference between Moissanite and natural diamonds?

Only an experienced gemologist or jeweler can tell the difference between the two. You can't just tell the two apart with the naked eye.
You will need a magnifying glass to look at the crown of the stone at a specific angle. Moissanite is doubly refracted and there's a chance you'll see shades of yellow and blue, unlike diamond, which doesn't refract.Diamond Nexus vs. Moissanite: Side-by-Side Comparison Guide (9)

Are Nexus Lab Diamonds real?

No, these are proprietary lab-grown stones and are simulation diamonds. They imitate real diamond, but their chemical properties, hardness and clarity differ from mined diamonds.

Are lab-grown diamonds worth it?

If you're on a tight budget but love the sparkle of a diamond, lab-grown diamonds are worth it! The best part is that synthetic diamonds mimic real diamonds and are available for a fraction of the cost of diamonds. Good quality lab grown diamonds do not chip and last forever!

You will always see positive and negative reviews about Diamond Nexus and moissanite, but I always believe that gemstones last longer if they are cared for.

Buying gemstones can be a challenge, especially with so many gemstone stores popping up every month. The right way to choose the best one is to check the reviews first, if someone in your circle bought a gemstone from the same store you chose, ask for honest reviews.

Carefully read the seller's warranty and product warranties, and always make sure you obtain a warranty card after purchase. This will help you to return and exchange the item if it is damaged, scratched or broken.

Before you decide to buy any one, consider your budget. Simulants can never be true substitutes for mined diamonds, but they are no less. If you're looking for ethical gemstones, these are your best bets!
