What Is Moissanite?

Moissanite has been called "Space Diamond" and "Stardust" because it is believed that naturally occurring moissanite has been found in meteorites. This colorless gemstone was discovered by Henri Moissan, a French scientist who had been digging around in crater in Arizona in 1893. He originally thought he'd found a diamond, but it turned out to be an entirely new gemstone that would be called moissanite. 

There's a lot of conflicting information about moissanite stones. Is it a diamond? Is it a fake diamond? A diamond simulant? A gemstone? There are many misconceptions and preconceived notions of this flashy stone. Naturally occurring moissanite is so rare in existence, that all moissanite jewelry is created in a laboratory.

Our Top Pick For Buying Moissanite Rings Online: Brilliant Earth

While we at Learning Jewelry love to talk diamonds and lab diamonds, we can't ignore the fact that many people are on the hunt for the most popular diamond alternative, moissanite. 

A lot of our recommended retailers don't carry moissanite-but our friends at Brilliant Earth do. 

Brilliant Earth also offers you the unique experience of being able to choose a loose moissanite online. Out of the few popular retailers online that do sell moissanite usually sell it as a whole engagement ring rather than loose stone and setting. 

The moissanite qualities seem to be separated into three categories: standard, premium, and super premium. Both premium and super premium are labeled while standard isn't. I also like that they have a variety of different moissanite shapes to choose from. 

Brilliant Earth's ring settings are among my personal favorites because they have a lot of different styles that I don't see on other retailer sites. And the fact that you can choose your own setting for the moissanite center stone you've picked out id hard to do without having to leave your home.

Brilliant Earth makes it possible, whether it's in one of their 30 showrooms across the US, online at virtual appointment with a gemologist, or at your own leisure building on their website. 

A neat additional feature to their clear and controllable 360˚ video is the Skin Tone changer. Brilliant Earth believes that having viewable options for different color skin tones will help people of color choose a ring to fit their skin tone. Other recommended retailers don't have anything like this. 

Furthermore, Brilliant Earth is also philanthropic for both people of color and female artisanal miners. They loved to give back and support equality and ethics on all fronts. 

If you want a routine maintenance warranty that's going to cover your rhodium plating for your white gold settings, prong retipping, and stone tightening, you'll have to purchase a Extended Service Plan. The cost is based on the item you purchase and it lasts three years. You also have the option of renewing it at the end of those three years. 

Is Moissanite Good For An Engagement Ring?

Moissanite rings make a fine choice for someone who wants an alternative to the diamond. Perhaps they want something different, or perhaps they're looking for something more affordable that looks like a real diamond. Whatever the case may be, moissanite makes a good engagement ring. 

One of the measurements we used in determining if a gemstone is fit for engagement or wedding ring purposes, is to measure it on the Moh scale. The Mineral of Hardness scale assesses to the hardness and durability of all minerals. A diamond reaches a 10 on the Moh scale, which is the hardest mineral on Earth. Moissanites reach a 9.25 on the Moh scale, making them the second hardest mineral on Earth. 

Moissanites aren't changed by heat like diamonds, so there's no need to worry about a jeweler's torch altering it during repairs. They are also brighter and flashier than diamonds, especially in sunlight. Some find it a bit too much for everyday wear, so you should see videos of moissanite in the sunlight before choosing it as an engagement ring. 

The main drawback to having a moissanite ring is that it doesn't usually have a trade in value and it's almost as expensive as a real diamond. Natural diamonds have both trade-in and investment values. For diamond engagement rings with a trade-in benefit, check out James Allen's lifetime upgrade benefits here.

Are Moissanite Rings More Expensive Than Diamond Rings?

Moissanite rings are definitely one of the pricier diamond alternatives, but they don't cost as much as diamonds. It's not uncommon for a moissanite center stone to be thousands of dollars. But when compared to a diamond, there is a distinct difference in cost. 

A nice quality one carat moissanite should only set you back about $500, while the average price of a high quality diamond is $4,000. But the price of moissanite engagement rings depend on the company and if it's a premium moissanite. Moissanite rings should never cost more than a natural diamond engagement ring.

What Should You Look For When Buying Moissanite Rings Online?

Natural diamonds follow the grading scale set forth by the GIA, the 4Cs. Moissanite's don't have a recognizable grading scale from the GIA. However, there are guidelines under the same principles that can be applied when buying moissanite stones.

Moissanite cut refers to the proportions and symmetry that allow light to pass through displaying brilliance and fire. Brilliance is the white light in a sparkle and fire is the rainbow light. Premium quality moissanite like the Forever One Moissanite from Charles and Colvard is cut the strict proportions that moissanites need in order to shine bright. 

Moissanites actually shine brighter than a diamond, which some actually find distracting, or even tacky. Diamonds have a refractive index of 2.4 and moissanites have a refractive index of 2.6, making the brilliance more intense than a diamond. 

While there is not an official cut grade for any moissanite shape, most people prefer the round cut moissanite. Some fancy shapes like princess, pear, radiant, Asscher, and marquise can be moissanite stones.

When moissanites were first becoming popular, they weren't always colorless. All moissanites contained a hint of color, usually yellow or brownish. These colors may be comparable to diamond color grade of J-M. 

Today, moissanites can be found in a range of colors, exactly like the GIA's color grade system for natural diamonds. The color grades for both moissanite and diamond is DEF, GHI, and J-M. Super premium moissanites are colorless D-F. Premium moissanites are near colorless G-I. JKL have faint tint to them and are regular moissanite. Moissanites with faint color hues of yellow or brown will look nice in rose gold or yellow gold bridal sets. 

You should be aware that even colorless moissanite doesn't always look colorless. Moissanite's color changes in lighting, which is one reason why people opt for the steady color display of a natural mined diamond.  


When a stone is created in a lab like moissanite, it doesn't usually leave inclusions or imperfection in the stone. With diamonds, you're more likely to find bits of crystal trapped in the stone. Moissanites will always be eye-clean, but diamonds will cost more to be eye-clean. 


Moissanites allow you to get bigger bling for your buck and costs you less. This is a huge reason why people may opt for a moissanite ring as an alternative to diamond. We said earlier that a loose 1 carat diamond of high quality costs around $4000. Instead of thinking about moissanites in carats, let's consider the size. 

A one carat diamond is about 6.5mm. A colorless moissanite that costs $4000 will be roughly 11mm. That's how much larger a stone you can get. Of course, you'll want to keep in mind that the blinding sparkle of moissanite increases its effect the larger the stone is.

Red Flags When Buying Moissanite Rings Online?

You shouldn't come into many issues if you're purposely seeking a moissanite ring. The main red flag when it comes to moissanite is misrepresentation. At some places, you'll see moissanite called a "moissanite diamond". This is incredibly misleading. A moissanite may look like a diamond, but the composition is completely different. 

Therein lies the problem when buying moissanite. A person who is looking for a diamond may come across moissanite diamonds and think it's the real thing. Some jewelry stores have even duped their customers into purchasing a moissanite under the impression of it being a diamond, like this article here

The other thing you want to look out when buying moissanite rings is just misinformation. There's a lot of inconsistencies in the moissanite market where people claim that they are almost the same as a diamond, when the two are very different.

Others may tell you that moissanite is a type of diamond, which it isn't. It's a gemstone all on its own. Some will tell you the value of a moissanite will increase over time. There is a very small chance of that happening. Natural diamonds don't go up in value, they stay the same.

Moissanites do too. Colorless moissanites may not always appear colorless. These are some of the things that a moissanite seller may not tell you when you're shopping around for a moissanite ring. 

How to get the Best Deal When Buying Moissanite Rings Online?

Make Sure You Can See the Stone

There are two reasons why you want to observe moissanite before you go and purchase one in your cart. We've talked about how a moissanite ring has a higher show of light than a diamond. Here's a good video comparison of a Harro Gem moissanite, a natural diamond, and a Forever One super premium moissanite from Charles & Colvard.

I have to say, the flashiness is a bit much for me, especially when it comes to shaded light on the Forever One moissanite. The white light is so overwhelming that I can't even tell there's a stone beyond all that light. I prefer the subtle, yet sparkly look of the diamond in the center. I can see deep into the stone while still enjoy the rainbow light and sparkle. The Harro Gem also looks too gray to me in some lighting and then too flashy in other. I like that diamonds stay close to the same in sunlight or shade. 

Make sure you have a good idea of what you're buying before you buy it, even if you have to search for videos yourself. Many companies won't provide high quality videos like they do with diamonds, for moissanite. This is another reason why some prefer diamonds. James Allen uses a 360 viewing technology that allows you to see their diamonds and synthetic diamonds up close and personal.

Remember the Warranty

A good thing to remember is the setting of your ring. If your moissanite ring is white gold, you're going to want a lifetime warranty. White gold needs rhodium plating, which has to be done in order to keep its silvery white color.

Prongs will have to be retipped and stones may need to be tightened. Don't forget about resizing either. It might be difficult to find someone that will replace your moissanite stone it it falls out. Cover your bases with a decent warranty that you can live with.
