Which Is Better, Moissanite or Diamond?

What's better is all about what’s important to you and you alone! But there is another high-quality, near-colorless gemstone with tons of sparkle on the market to give diamond a run for its money—moissanite!

My 1ct moissanite white gold solstice ring looks like a diamond. This ring was purchased second-hand and was the test piece I wore to prove to my now-husband that moissanite was the way to go for my engagement ring. It just made sense financially, and I have an extremely beautiful ring that is often admired by complete strangers.

This article was written as a way to share the mountain of research that helped us decide that moissanite suited us better than diamond. In the sections below, you'll find:

  • spec comparisons,
  • facts on both gems,
  • price comparisons, and
  • a few places to shop.

It is all about comparing moissanite and diamond.

Happy gemstone shopping, and if it's a moissanite engagement ring you're looking for, a very big congratulations to you!

Moissanite vs. Diamond: Differences and Similarities

When comparing diamond and moissanite stones, you may be surprised to learn that many claim moissanite as a superior gemstone. Here are some reasons why.


Moissanite is a near colorless gemstone.

Most common Diamonds are classified in this range.

Moissanite ranks 9.25 on the Mohs Hardness scale making it the second hardest gem.

Diamond ranks 10 making it the hardest gem.

Moissanite possess more fire or dispersion (the flashes) at .104.

Diamond rates considerably lower at .044.

Moissanite also has a higher refractive index or brilliance (the sparkle) at 2.65.

Diamond comes in at 2.42.

Moissanite is only available as a lab-created stone as its natural state is not found on Earth (it was discovered in a meteorite).

Diamond is readily available in its natural state and there are now companies creating lab-created diamond see Apollo, Gemesis, Takara or even Life Gem.

Moissanite costs a fraction of its diamond equivalent.

Diamonds are sold to us as an "investment", but the average consumer isn't purchasing investment grade stones and very few jewelers will buy them back at full price unless you "upgrade" with a more expensive stone.

One company, Charles and Colvard, holds the patent for jewelry grade moissanite.

One company has been known for controlling the diamond market and its prices.

Moissanites are hand cut with optical properties that best show off the stone.

Diamonds are hand cut with optical properties that best show off the stone.

The 4 C's of Moissanite

Although an official grading system is not in place, the majority of moissanites fall into the diamond grading scale of the 4 C's.

1. Color

The gem typically falls into the near-colorless range of a diamond F-G-H-I, but a slight green or yellowish undertone can be found in some stones in particular lighting. Round Brilliant faces up the whitest and is by far the most popular shape in moissanite. Fancy shapes like pear will hold more of the slight green/yellow body color and may lean more towards I-J-K.

The larger the moissanite, the more apparent the body color. When buying from any online store where you won't be able to see the moissanite before purchasing, make sure they have a return policy in case you get a stone with more color than you like. It is worth noting that if you enjoy warmer diamonds, you may really love the color in a warm moissanite. The incredible sparkle moissanites produce will often mask any color issues.

Some companies are now offering moissanites with special coatings or treatments to create pink, yellow, blue, and green stones. These coatings often void the manufacturer warranty, but the jeweler itself may offer a guarantee. The vast majority of manufactured moissanites are near-colorless, though rare non-coated greens do exist. Moissanite manufacturer Charles and Colvard has recently created a "Forever Brilliant" line of moissanite said to be up to 2-3 times whiter than the original. For fancy shapes like pear, "Forever Brilliant" would be something to look into.

2. Clarity

VS1-VS2. Moissanite should always be eye clean, but under magnification, needle- or tube-like inclusions from the creation process can be seen.

3. Carat

Keep in mind that carat is a weight, not a size. Gemstones are typically sized by millimeters. For example, a 6.5mm round moissanite is the equivalent to a 1ct round diamond. Check out the Actual Diamond Sizes for a complete list of millimeter sizes by carat weight.

4. Cut

Moissanite would not be as beautiful if it were cut to the same proportions as diamond due to differing optical properties.

Moissanite vs. Diamond Price Comparison

Moissanite is more expensive than the average cubic zirconia, but you are also buying a man-made gemstone (hand cut) that is going to keep its beauty as well as diamond does, unlike your average cubic zirconia, which clouds and scratches after a relatively short time.

To compare the prices of diamonds and moissanites, I used Blue Nile's search engine to filter for the 4 C's in which moissanite is equivalent to diamond to show you the difference in price. I chose the cheapest diamond of the selection. (This comparison was last updated on July 15, 2015.)

DiamondDiamond PricePrice of Equivalent MoissanitePrice Difference

.5 CT Ideal Cut, I Color, VS1




.75 CT Ideal Cut, I Color, VS2




1 CT Ideal Cut, I Color, VS2




1.5 CT Ideal Cut, I Color, VS1




2 CT Ideal Cut, I Color, VS2




3 CT Ideal Cut, I Color, VS2




4 CT Ideal Cut, I Color, VS1




The filter selections were as follows. Color: F-I, clarity: VS1-VS2, cut: ideal, carat: see below, shape: round. The prices on moissanite come from the MoissaniteCo website's regular moissanite loose stone selection. Please note that moissanite is also sold with a whitening treatment (branded Amora Moissanite) or fancy colored treatments at a higher price point.

Considering a Moissanite Engagement Ring?

You're probably thinking, "Wow, so I'll save lots of money with a moissanite engagement ring!" Probably, but do not make that choice without her.

When offered a diamond, most women will not turn it down, but that doesn't mean there aren't other alternatives that are just as beautiful, if not more. However—and take this advice as what you may gentleman—society has us trained to think that diamonds and engagement go hand in hand. Buying an alternative gem without being 100% sure of her opinion may get an unpleasant reaction. Even more dubious is trying to pass that alternative off as a diamond. One day while getting her ring cleaned at a jeweler's she will find out the truth, and it probably won't turn out pretty. As long as your beloved knows the truth, no one else has to.

The best news is that since just about all of us are so diamond-engagement-brainwashed, we'll automatically accept a high quality colorless gem like moissanite in an engagement ring as diamond. With a sparkle like moissanite has it's hard not to think of it like a diamond. My 3-stone engagement ring in the picture above is fawned over by strangers that have no idea it isn't "real". Especially mall jewelers... they coo over my "ideal" cut, sparkly diamond.

Does moissanite sound like your dream come true for an engagement ring, but you aren't sure how to get your lady on board? Try introducing the gem as another jewelry gift. It'll be your chance to educate her and fall in love with the stone on her own.

Reasons I Told My Fiancé to Skip the Diamond

  1. I wanted a high quality elaborate setting. Most diamond jewelers pushed us to spend the majority of our budget on the stone and skimp on the setting.
  2. I couldn't justify spending thousands and then having my heart stop if I happen to drop my ring on the tile bathroom floor or if the cat decides to use it as a hockey puck down the floor vent or, god forbid, someone were to steal it. (Update: My heart still stops every time I even bump my engagement ring... but it's not for fear of what it cost; it's because it's so darn gorgeous I don't want to ever hurt it. I'm very clumsy and hard on my jewelry and I have yet to scratch or ding any of my moissanite from my 6-year-old pieces to my wedding set. All the stones are as gorgeous as the day I got them.)
  3. I still wanted a colorless diamond-like gem with great sparkle that wouldn't become cloudy or scratched up. Moissanite fits that. Cubic zirconia doesn't. Other colorless gemstones, like white sapphire, lacked the fire and sparkle. Moissanite has more than even diamond.
  4. I own other moissanite pieces, love them and get compliments on them. And yes, people assume they are diamonds unless I tell them otherwise. Sometimes I do and sometimes I just smile at their presumptuousness. Moissanite isn't well known where I live, which is probably why so many are fooled into thinking it is a diamond.
  5. I don't put a whole lot of stock into what others think about my engagement and wedding rings. I love them and my husband is proud of them, and that's what matters most. However, there are people that turned their noses up, or rather looked down on us after we told them the ring they were just admiring isn't actually a diamond. My husband, who took a while to convince, now looks at this kind of turn about reaction as a way these people justify their own preconceived notions on diamonds, especially the ones that have plunked down quite a bit more cash for rings not nearly as impressive. After all, he felt that way once, too.
  6. We've been to Jamaica twice on the money that would have been tied up on my wedding set if we purchased it in diamond.

Moissanite Earrings

Spectacular 1 CTW Moissanite Stud Earrings are a classic look at a much better price than diamond offers. Diamond studs are a classic look that should be in every woman's jewelry wardrobe. Moissanite can give you the same look for much less. You even get more sparkle and in turn a much more eyecatching look when wearing moissanite. My own pair are in my ears nearly every day.

Moissanite comes from a meteorite and does not have the same chemical make-up as a diamond.

Why Moissanite Is Not Conidered a Man-Made Diamond

Moissanite is classified as a gemstone in its own right, not a diamond simulant.

  1. Moissanite does not have the same chemical make-up as a diamond. Moissanite was discovered from a fallen star, a meteorite. It's not an element that's natural to earth, which diamond is. It's rarer than that!
  2. Moissanite is double-refractive (the reason it throws off more sparkles). Diamond is single-refractive. To a trained eye, this is the most common trait that will "give away" a moissanite. It's difficult to see without examining closely, unless you have a rather large stone.
  3. Moissanite is naturally green. Diamonds can be colored, too, but colorless diamonds are actually the most common.
  4. Moissanite is not graded like diamonds. It's all priced by size and treated the same regardless of any color differences. This was the manufacturer's choice to keep prices lower by selling more of their inventory.

Nothing Can Beat That Sparkle

The beauty of a moissanite's sparkle on a sunny day simply can't be beat. The videos included here seriously do not do the stone justice. Moissanite also sparkles like mad in romantic lighting situations. One of my favorite parts of owning a moissanite wedding set is seeing how it reacts in different lighting. As mentioned earlier, overcast days can cause a lackluster look, but even diamonds don't sparkle the same in every setting.

Do Your Gemstone Homework

These are some good resources for doing your own research so you can buy with confidence.

  • Actual Diamond Sizes—Blue Nile
    Remember carat weight is not the same as visual size. Two one carat diamonds can be different MM sizes, meaning one will look bigger than the other depending on how it was cut. There are however some average standards.
  • Moissanite—Wikipedia
    It's used for much more than just jewelry.
  • Diamond Color Chart—GIA Diamond Color Scale
    Keep in mind that moissanite is not graded for color, but learning about diamond color can help you decide if moissanite will work for you.
  • Fancy Colored Moissanite
    Yellow moissanite is absolutely stunning. the same company that came up with the enhanced moissanite also offers a similar treatment that creates colored moissanite stones.
  • Charles & Colvard
    The manufacture and patent holder for jewelry quality moissanite.

Readers Choose: Moissanite or Diamond?


I don't think any woman is particularly concerned with the slight difference in hardness of the stone. In all of other aspects, it is as good or better than a diamond. - careermom

Diamond all day long. - luvhammers

More sparkle and fire than diamond, harder than sapphires, won't scratch or cloud with time like CZ, isn't associated with the blood diamond industry in any way, and easier on the pocketbook. Yep, I'm clearly on the moissanite side. :) - pixelposy

diamond - victoriahaneveer

Just for you...moissanite! - UKGhostwriter

Diamonds are harder! - thefun4kids

thought your lens was very interesting, I would go for the moissanite. - marybeadz

Moissanite is beautiful, but diamonds are still diamonds. - TolovajWordsmith

Funnily enough, it is me (the girl) convincing the guy to look at Moissanite instead of diamond. The main reason being that I like a lot of flash and large rings, but would much rather put that diamond money to use as the down payment for our home. - Twitterpate

Sigh! Whatever you say, it is hard to get over the idea of 'Diamond is woman's best friend.' - krish218

I have a moissanite ring set in a 14 k white gold cigar band setting, it is beautiful and I would never buy a diamond again. It gets complimented all the time. . . Financially it made sense and when I saw it for the first time, personally it made me feel great. - chachingck1

Diamonds are harder, and therefore cooler. - GetSillyProduct

I don't see the point of paying for real stones, when the manufactured ones tend to be just as nice. - KarenCookieJar

In my humble opinion, I say diamond. - Wonderful Wedding

Beese on April 20, 2017:

Fantastic article! And I couldn't agree more on every point you made! I was introduced to moissanite in 2007 when my ex purchased a 3 stone engagement ring in white gold for me. However, he lied & told me they were diamonds... My friends & co-workers were blown away by how perfect & sparkly my "diamonds" were. Frankly, so was I! I ended up selling it on eBay for the deposit on my apt. after we split. But I was now hooked! Years later, my real future husband gave me a lovely, high set, white gold engagement ring w/milgrain edging & diamonds down each sidem. Unfortunately, I love BIG & flashy so I ended up replacing the 1/3 ct center diamond w/ a 1ct RB moissanite. There is no discernable difference between the diamonds & moissanite. I still wear the ring but always stack it or wear on my rt. hand. I've since purchased 4 more moissanite rings, each bigger than the last (the dreaded "shrinkage" sets in quickly for me!) :) I have a 2 ct RB set in platinum plated sterling, a 3.5 RB set in yellow gold w/.5 ct of round channel set moissanite in the band. Along w/a matching 1.5 ct channel set anniversary/wedding band. And most recently purchased a 3 ct Forever Brilliant RB set in a white gold, very thin, plain band (Tiffany style). I love them all & as the author states, moissanite can be moody at times but I think it just gives them more character! And no matter what, they sparkle like crazy, even when in desperate need of a cleaning. Also, aside from the one Forever Brilliant, they're all Charles & Colvard original classic. I've noticed in all of my larger stones, that I never see the dreaded nail head or "black hole" in the center that having a large culet often causes. And the classic stones are just as white & lovely as the FB. I'd love to see the new Forever 1 stones in real life. Everything I've heard/read has been extremely positive. And it's good to know that they aren't using any coatings as they did in the gen 1 FB stones - they've managed to develop their F1 rough to be in the D-F grades w/no after treatment needed. I'm sorry for such a long post! Bottom line, I LOVE my moissanite & will likely never purchase another diamond! Oh! One more thing, stay away from the moissanite from India for now if you're looking for a very white stone, as they're almost always off white at best. Most vendors seem to still use sub-par cutting methods. Although, I did just purchase a cheap $30 3 ct cushion cut to possibly use in a future project! I want to see for myself if it's any good & it's an inexpensive way to try out a new cut (new to me!) I'm curious to see if the prices in the U.S. will change at all now that C&C's patent has expired. Thank you for letting me babble! :) on January 12, 2017:

I think whether it is an accessory, Ring, arm ornaments, and so forth you can't contrast them and each other. We ought to dependably wear what suits our identity and improve our looks. Each individual has its own decision. Somebody like Earrings, Rings, Bracelets. Be that as it may, i like Diamond Jewelry most.

Twitterpate on May 10, 2014:

Funnily enough, it is me (the girl) convincing the guy to look at Moissanite instead of diamond. The main reason being that I like a lot of flash and large rings, but would much rather put that diamond money to use as the down payment for our home. I look at it like this -> I have a rarer stone than a diamond..beat that! Also, we are 46 and 51 respectively, and we were actually each other's first marriage. Almost 30 years later, we've reconnected and really enjoy our past, present, and future we want something a little different, a little more "us" than the standard. And this does that. :)

chachingck1 on February 08, 2014:

I have a moissanite ring set in a 14 k white gold cigar band setting, it is beautiful and I would never buy a diamond again. It gets complimented all the time and because it is a large setting I only wear one band. I too had reservations, but bought the loose oval stone and a setting for it and have never regretted a moment of my decision. Financially it made sense and when I saw it for the first time, personally it made me feel great.

chiclisa on March 05, 2013:

thank you for sharing all this important information about diamonds. Like you mention in this article, color, size, cut and clarity are what determine the price of the stone.

GerryR321 on January 13, 2012:

I agree, it is completely personal preference. Some ladies want the real deal, and some don't mind the synthetics.

The only method we still use for testing stones is a diamond scratch test, and the diamond will still scratch and cut up a moissanite. Hardness is not even close to diamond, closer than other gems yes, but close.... NO. Fact is, it is about 240 points away from the hardness of diamond.

Hardest synthetic known though, I give it that.

JackieSonia on December 27, 2011:

Ah! Que belleza!! If I had to do it over again, I would want my engagement ring to be moissanite. Thanks for your lens. Had never heard of moissanite before. But will keep it in mind for future jewelry.

Great lens full of info. that I never have heard of at all. Love jewelry but am rough on it so anything that looks beautiful but I don't have to lay out mucho money for is great. My mom gave me a valuable diamond ring and within a month it was missing 2 of the smaller diamonds!!! guess u shouldn't wear good jewelry when u rock climb!!! Great lens. Really interesting.

@mustang417: No worries, I can fix it! Thank you for sharing your moissanite story. I totally agree with your smart customers! For the money you can get a show stopper stunner of a ring in moissanite, or a flat and marked diamond that's only quality is you can say it is diamond! No contest for me, moissanite wins!

Very good advice when buying diamonds to have them tested for moissanite. Moissanite can fool even jewelers equipment.

mustang417 on September 22, 2011:

@mustang417: I do not know why this posted twice, and I do not know how to remove one of them. I apologize!

mustang417 on September 22, 2011:

I too, own a moissanite! I bought mine for myself at JCPenney and it looks exactly like your first picture of the round stone in the 6 prong 14k white gold setting... I am always asked where I got it from (happens to also be my place of work) so it was a great upsale! Most people don't "buy" into it though because it does not have the name diamond. I have converted so many of my customers towards moissanite and I am glad you have this posted so if they research it on their own, they know they did the right thing! (I am not engaged but do wear it on my left hand so they guys have something to compare their purchase to) =) Also, as a little side note, a Moissanite is so close to a diamond it will read on a diamond probe as a diamond, so diamond buyers beware, ask your jeweler to use a moissanite probe just to be sure because a diamond will not probe on a moissanite probe.

Serj on June 16, 2011:

Wow, what a great lens. I love the price difference, diamonds prices are manipulated by the DeBeers family anyway... they have a hugely abundant supply of them, but they make it seem like they are rare to drive up the price... before that diamonds were way cheaper... great strategy and excellent marketing (Diamonds are forever) are what keeps diamonds that way. Moissanite should use that strategy but perhaps use something along the lines of "So beautiful that it was shared with us by God." or something similar to that, referring to it's coming to us via an astroid

pixelposy (author) on May 12, 2011:

@sarebear: It kind of sounds like you're the perfect candidate for moissanite. Especially if you'll enjoy sharing it with others rather than being embarrassed it's not diamond. Really the only people I see on the boards that are unhappy with moissanite are those that expect it to look and perform the same as a diamond. IMO it outperforms it, but it does have that cloudy bad lighting drawback where it can appear dull and warm. This bothered me the first few times I saw it, but now I kind of smile and just think my ring is having a moody day. It happens very infrequently.

Gorgeous setting, I like the delicateness of the band. It'll be like moissanite is almost floating on your finger. That would look great if you like the double wedding band look too.

Yep, almost all the pictures are of my moissanite. My wedding set is pictures in the poll just above this comment section. And if you go to the top of the page you'll see in the header a link for "Photos of Moissanite". There are quite a few there in different lighting. It's a 1ct center moissanite with 2-.25ct side stones and probably 1-2.5mm graduated side stones on the bands. All un-enhanced. It came from a company that is no longer in business. I catch strangers admiring it all the time, and people can't help but comment when I'm somewhere where the lighting is causing it to sparkle like mad. Even the tiny stones throw off so many flashes of color and sparkles.
