The Difference Between Moissanite Vs. Lab-Grown Diamonds

You likely think of prestige, elegance, and durability when you see a glittering diamond. This symbolism is closely linked to the stone’s rare status and legendarily durable make-up.

Sadly, diamonds are also costly as a result. The diamond industry has seen slowing interest among younger demographics these past few years, leading many to wonder what alternatives could crop up. Enter the brilliant moissanite stone, a gem held up as a (literally) shining example of affordability.

“But wait…aren’t lab-grown diamonds similar?”, you might be asking. Let’s look at the difference between the lab-grown moissanite and the lab-grown diamond below.

The State of Today’s Diamond Industry

Why are fewer people buying diamonds these days? This trend is widely considered to be caused by high prices and the inherent difficulty of the territory.

Does that mean there’s no demand for diamond-based jewelry? The year 2019 alone saw over 140 million diamond carats produced, a pretty stunning record when you consider how hard these stones are to find! Lab-grown diamonds have been doing pretty well, with industry projects stating 2030 will be the best year for production yet.

In-between all the numbers and techniques, there’s one question: should you buy a lab-grown diamond or a lab-grown moissanite for your next necklace? These two stones are very similar, leading to confusion among jewelry buyers.

Defining the Diamond

Diamonds are well-known as the hardest substance around. These stones hit an impressive 10 on the Mohs scale, created by extreme conditions.

Diamonds usually come in transparent forms but also in pink and golden varieties. 

How are Lab-Grown Diamonds Made?

It may seem like an impossible feat to create a lab-grown diamond. How can humans possibly recreate the conditions needed to craft these beautiful stones?

As it stands, lab-grown diamonds are crafted with advanced technology and a careful hand.  Experienced scientists have figured out how to recreate the intensely hot and heavy pressures needed to turn carbon into a stone. 

How hot does a scientist need to go to craft a diamond? Over 2,000 degrees Fahrenheit!

How is Moissanite Made?

Similar to lab-grown diamonds, human hands craft moissanite. The most significant difference is that diamonds still occur naturally, while moissanite is 100% synthetic.

Does that mean moissanite isn’t as beautiful or sturdy? You’ll be glad to know that moissanite is pretty sturdy, wavering around 9 on the Mohs scale of hardness. The stone’s luster is also rather impressive, having a diamond-like feel with an opal-like sheen. Moissanite stones are pretty colorful and usually have a green or yellow hue.

Moissanite combines carbon and silicon, resulting in the gorgeous diamond alternative we know and love today.

What’s the Difference Between Moissanite vs Lab-Grown Diamonds?

Now for the test! Moissanite and lab-grown diamonds are very similar overall, but there are a few differences to keep in mind.

Diamonds are a Little Harder

To date, moissanite hits around 9 on the Mohs scale. This scale determines the density and longevity of various minerals. Diamonds are the most durable, knocking everything out of the park with a solid 10.

Moissanite is More Glittery and Tinted

Diamonds tend to be very crisp and clear, leaning toward silvery or blushy hues. Moissanite is more similar to opal due to how it refracts light, filling it with pink, green, and yellow speckles.

Moissanite Uses Two Materials

Diamonds are made out of very dense carbon. Moissanite is made out of both carbon and silicon. 

Silicon is a mineral that’s usually quite brittle, though it boasts an impressive metallic sheen.

Is Moissanite Cheaper Than a Lab-Grown Diamond?

With so many similarities, you’re probably wondering what to expect concerning price. Overall, lab-grown diamonds are still a little more expensive than moissanite.

The reasons for this are usually due to diamonds being perceived as fancier. Lab-grown diamonds are still denser than their moissanite counterparts. On the other hand, the moissanite stone’s quintessential coloration is appealing to some buyers. You might prefer a twinkly, colorful stone over a simpler one!

Distinguishing Moissanite and Lab Grown Diamonds from Natural Diamonds

For many people, lab-grown diamonds and moissanite have an almost identical appearance to those natural diamonds. With that, it can be challenging to differentiate them without the help of an expert. In fact, those lab-grown diamonds have the same chemical composition and physical appearance as their natural counterparts. While they may possess different physical characteristics, you will need specialized equipment to test those materials' hardness, sparkle, and reflection. Lab-grown diamonds and moissanite stones are designed to mimic natural diamonds' appearance, but they often still differ slightly from the real gems. 

Can Moissanite and Lab Grown Diamonds Have Certificates? 

Like an authentic diamond, both lab-grown diamonds and moissanite can be certified to guarantee their authenticity. In the certifications, you will receive the same information as a traditional diamond, including data regarding the cut, clarity, color, and carat weight. Many moissanite gems are certified by a third-party organization. Those lab-grown diamonds can also receive an IGI certification. Depending on your jewelry supplier, they may have their own certifications for these pieces.

Which One To Choose?

Both of these stones are sustainable and conflict-free. Lab-grown or moissanite are the better options if you want the look of a natural diamond but don't have the budget or want sustainable choices. These stones often cost a fraction of an actual diamond but still possess those outstanding features. In many cases, it will take a trained professional and special equipment to identify any of the differences in these stones. Depending on your needs and budget, you might prefer one type of diamond over the other. 

If you want to maximize your savings or want a larger carat size, then make sure to select moissanite. 

If you want something that mimics the exact features of a diamond without the sustainability issues, choose the lab-grown ones.

Do Moissanite and Lab Grown Diamonds Pass the Diamond Test? 

If you want to authenticate these gemstones, they tend to test positive by a diamond tester. These testers will measure the amount of heat emitted from the stone, which indicates its hardness. With these tests, you can know that the stones are genuine. 

Which One Has More Value?

Many of these stones do not hold up in value. The prices of lab diamonds are constantly fluctuating, and there is a good chance that they will be worth less in the future. Over the years, the price of lab-grown diamonds continues to fall. For that reason, many jewelers will not offer a trade-up policy for these diamonds. There is too much risk in the deal. 

Moissanite stones don't have significant value because they are not rare gemstones. While they may have the same features as a diamond, they are not genuine diamonds. Despite all the controversy surrounding the mining and selling of diamonds, these authentic diamonds are still highly prized on the market. If you want these stones, do it for more sentimental reasons than those monetary ones. No matter what, both lab-grown diamonds and moissanite are beautiful stones that will enhance the look of any piece.


Which one to buy for your jewelry case? The difference between moissanite and lab-grown diamonds are few, but significant.

Moissanite is 100% lab-grown. This stone does not occur naturally and is crafted with the aid of skilled scientists and advanced technology. Moissanite jewelry is favored for being very durable and having a brilliantly colorful result. If you’re on a budget, moissanite also tends to be more affordable than naturally occurring diamonds or lab-grown diamonds. 

To contrast, diamonds still occur in nature, though they are created synthetically. Lab-grown diamonds are still more dense than moissanite, hitting a 10 on the Mohs scale (the highest you can go). They also have a clear and simple color, which is highly appealing for some buyers.
