    The current market value of moissanite jewelry is $1.3 billion, and it is expected to reach $2.30 billion to $2.97 billion. That is a booming market. Especially among younger buyers, moissanite engagement rings are very trending. But on the other side, there are so many things that confuse people and hold them back from buying moissanite engagement rings.

    That is why this blog exists: to help you decide whether to jump into this booming market and buy lab-created moissanite engagement rings, or hold off and look elsewhere. Let's find out. 

    What is Moissanite

    Moissanite is the gemstone found in 1893 by the chemist Henri Moissan while studying a meteor crater. At first glance, he thought he had found a diamond in the meteor crater, but after studying its chemical structure, he realized it was not a diamond; it was a diamond-like gemstone. Because it had been found in a meteor crater, it is called a stardust gemstone.

    Moissanite looks exactly like a diamond, and people often get confused between diamond engagement rings and moissanite engagement rings. But several factors clearly differentiate between them, and conclude that moissanite jewelry will never replace diamond jewelry. Why would they not? Here are the reasons.

    Is Moissanite a Real Diamond?

    First and foremost, moissanite is not a real diamond . It is not even a fake diamond. It is a different gemstone in itself, carrying different chemical and physical attributes. It just looks like a diamond; that is it. Below is the detailed table of comparison between moissanite and diamond to help you understand the physical and chemical differences. There are other differences too, which you will discover one after another later in the guide.

    Differences Between Diamond and Moissanite

    Characteristic

    Moissanite

    Diamond

    What It Means for You

    Composition

    Silicon carbide (lab-created)

    Carbon (mined or lab-created)

    Both are real gemstones. Moissanite is always lab-made; diamonds can be either.

    Hardness

    9.25 Mohs

    10 Mohs

    Diamonds are slightly harder, but moissanite is hard enough for daily wear without scratching. The difference is barely noticeable in real life.

    Toughness

    Good

    Excellent

    Toughness = resistance to chipping/breaking. Diamonds are less prone to chipping if hit hard. Moissanite is still tough enough for engagement rings.

    Refractive Index

    2.65–2.69

    2.42

    This is the big visual difference. Moissanite bends light more, creating visible rainbow flashes. Diamonds show subtle white sparkle. Which you prefer is personal.

    Light Performance

    High "fire" (rainbow colors visible)

    Subtle sparkle (white/colorless)

    Moissanite's sparkle is more obvious from a distance. Some love it; some find it too "flashy." Diamonds appear more understated.

    Cut Quality Impact

    High impact on appearance

    High impact on appearance

    Both stones need good cutting to maximize sparkle. A poorly cut moissanite or diamond will look dull. A well-cut stone of either type will shine.

    Longevity/Durability

    Lasts a lifetime with normal care

    Lasts a lifetime with normal care

    Both are suitable for heirloom pieces if cared for properly. Neither will degrade over 50+ years of wear.

    Yellowing Over Time

    Older cuts (pre-2010) may show a faint yellow tint. Newer cuts: stay colorless

    Does not yellow over time

    If you buy from a reputable vendor using modern moissanite, this is not a concern. Older moissanite rings might show very slight yellowing.

    Maintenance

    Same as diamond

    Same as diamond

    No meaningful difference. Both need the same care routine.

    Scratching

    Extremely scratch-resistant; can scratch only by another moissanite or diamond.

    Most scratch-resistant; can scratch only by another diamond 

    In real life, neither stone scratches easily. Daily wear won't scratch either one.

    Heat Resistance

    High; withstands jewelry repair heat

    High; withstands jewelry repair heat

    Both are safe during professional jewelry repairs and resizing.

    Are There Different Grades of Moissanite Engagement Rings

    Yes, there are different grades of moissanite engagement rings depending on the quality of moissanite in them. Although moissanites do not have any organisation that controls their quality grading as GIA does for diamonds, moissanites are graded using the diamond grading system, where they are evaluated on their 4Cs , which include cut, clarity, color, and carat. 

    The Most Important C of the 4Cs for Moissanite Engagement Rings

    Out of the four Cs, the cut is the most important C to notice while buying moissanite engagement rings. Cut decides how well the moissanite sparkles. The moissanite engagement rings with an excellent cut stone will offer more sparkle than a poor cut stone. For moissanite engagement rings, it is recommended to have an excellent cut stone with D-E-F color.

    How Long Do Moissanite Rings Last?

    As you saw in the table, moissanite scores 9.25 on the Mohs scale against diamonds, which score a perfect 10. This means moissanite is slightly softer than diamond. But there are so many popular gemstones scoring less on the Mohs scale than moissanite, but they still make durable everyday wear jewelry. 

    These gemstones include ruby, emerald, sapphire, citrine, morganite, and amethyst. This data suggests that moissanite engagement rings are not as strong as diamond engagement rings, but they are able to last for generations with proper care.

    How Much Do Gold Moissanite Engagement Rings Cost?

    Moissanite is not a precious gemstone that is scarce like diamond, ruby, sapphire, and emerald. The majority of moissanites are created in the lab, and they are available in abundance. That is why moissanite engagement rings are way less expensive than diamond and even lab diamond engagement rings. 

    The average diamond engagement ring cost in the USA is $5,500 to $6,500. On the contrary, the average moissanite engagement ring cost is between $300 and $1,500, and this inexpensiveness is the reason affordable moissanite engagement rings are popular amongst younger buyers.

    Resale Value of a Moissanite Engagement Ring

    Because of less scarcity, historical weightage, and abundance, moissanite engagement rings do not generate resale value as much as diamond rings can. Natural diamonds retain 40–60% of their original cost when sold a second time. Lab-grown diamonds get 20–40%, and moissanite only acquires 10 to 30% of its original value in the resale market. 

    Does a Moissanite Engagement Ring Get Insured

    Yes, a moissanite engagement ring can absolutely be insured. Specialty jewelry insurance companies and standard homeowners/renters insurance providers treat moissanite and lab-grown stones the same way they treat natural diamonds. 

    Is Moissanite Ethical

    We often hear that stones being created in the laboratory are ethical, but that is just half the truth. Whether they are ethical or not cannot be justified just because they are made in a controlled environment. We have to look at the sources being used to run the laboratory. 

    If a lab is running with electricity produced by high carbon-emitting sources like coal, then it is questionable. But nowadays, so many lab-grown stone factories run with green energy. The moissanite and any lab-grown stone created in these factories can be classified as an ethical gemstone. 

    Can Cheap Moissanite Engagement Rings Make an Heirloom Piece

    Whether a moissanite engagement ring can be an heirloom piece or not depends on how your family sees an heirloom piece. If your family considers a piece that is durable and lasts for generations, then a moissanite engagement ring can absolutely be heirloom jewelry. 

    However, if your family wants expensive, royal, and traditional jewelry as an heirloom piece for financial investment, then it is always good to go with a precious stone ring with either diamond, ruby, sapphire, or emerald.

    Certification for Moissanite Engagement Ring

    There is no official, globally recognized, independent regulatory body that issues certificates for moissanite engagement rings. Unlike diamonds, which are rigorously certified by non-profit institutions like the GIA (Gemological Institute of America), moissanite certification functions entirely differently and requires careful consumer awareness. 

    Nearly all moissanite rings sold online by independent vendors come with a GRA (Gemological Research Association) Certificate.  The GRA is not a single, official, centralized laboratory. It is a generic name used by hundreds of manufacturing suppliers, primarily based in China, to print marketing materials. 

    How To Verify If Ring Has Moissanite Or CZ

    Cubic zirconia is a very inexpensive alternative to diamond and moissanite. As moissanite engagement rings do not provide authentic and standard certificates, buyers are often duped with cubic zirconia. So while buying moissanite engagement rings, test it to evaluate whether it really has moissanite or cubic zirconia. 

    The easiest way is to check if there is a number present on the girdle of the stone. But if the stone is already fitted in the ring, then you will have to use a moissanite-specific tester. 

    How to Tell if a stone is Moissanite or Diamond 

    If you're looking to buy a diamond engagement ring and worried about getting sold moissanite, then the first thing to look at is sparkle. Moissanite throws rainbow colors and bright flashes. Whereas a diamond is more subtle, it just throws white sparkles. That's the easiest way to spot the difference.

    If you want to confirm the technical aspect, use a magnifying glass and observe the stone. Moissanite's edges look a bit fuzzy or doubled. But the most effective way is always the simplest: ask for a gemstone grading certificate verified by GIA or IGI.

    Choosing the Perfect Setting for Moissanite Engagement Rings

    In terms of appearance and styling, moissanite engagement rings follow the same path as diamond engagement rings. As we have gone through all the differences between diamond and moissanite engagement rings, now we have nothing left to distinguish between moissanite and diamond. 

    As far as setting is concerned, all those settings that work well with diamond work well with moissanite too. The final destination depends on your preferences. We have a detailed guide on engagement ring settings where we have discussed all the major engagement ring settings and styles. Make sure you go through it and find the most suitable engagement ring setting for your moissanite engagement ring.

    Frequently Asked Questions

    Yes, you can safely wear a moissanite engagement ring while swimming, bathing, or doing dishes. Moissanite is not damaged by water or chlorine. However, avoid wearing it in extremely hot water for extended periods, as temperature fluctuations can occasionally affect the setting. For saltwater or pool environments, rinse the ring with fresh water afterward to prevent mineral buildup on the stone. Overall, moissanite is perfect for active lifestyles and outdoor activities.

    Moissanite is extremely scratch-resistant and ranks 9.25 on the Mohs hardness scale. In everyday wear, your moissanite ring will not scratch from normal activities like typing, exercising, or household chores. The only substances that can scratch moissanite are diamond and another moissanite stone. If you accidentally hit the stone against hard surfaces, the metal setting is more likely to be damaged than the stone itself.

    Clean your moissanite ring every 1–2 weeks with warm soapy water and a soft toothbrush to keep it looking brilliant. This simple routine removes daily dirt, oils, and residue. For a deeper clean every 6 months, take it to a professional jeweler who can ultrasonic clean it and inspect the setting for any loose prongs. Regular cleaning keeps your ring sparkling without requiring expensive maintenance.

    Moissanite and lab-grown diamonds are both excellent choices, but they're different. Lab diamonds have diamond properties and look identical to mined diamonds, so they appeal to people who want the "real diamond" experience at a lower cost. Moissanite is cheaper, more sparkly, and more ethical. Choose moissanite if you love the fire and want maximum affordability. Choose lab diamond if you want the diamond look without the mined gemstone concerns.

    Any shape works beautifully with moissanite, round, cushion, oval, emerald, radiant, or any other cut. Round brilliant cuts maximize sparkle and are the most popular. Cushion and radiant cuts enhance the rainbow fire that moissanite is known for. Emerald and asscher cuts show off color more prominently, so they're good if you prefer a more understated look. The best shape is whichever appeals to your personal style and preference.

    This depends on the seller's policy. Many reputable moissanite retailers offer exchange or upgrade programs within a certain timeframe (usually 30–60 days). Some sellers will credit part of your purchase toward a larger or higher-quality stone later. Always ask about the return and upgrade policy before buying. Reading the seller's terms and conditions protects your investment and gives you options if you change your mind.

    Older moissanite (pre-2010) can develop a slight yellow or gray tint over years of wear. However, modern moissanite production has improved significantly, and new moissanite stones stay colorless indefinitely. When buying moissanite, purchase from reputable vendors using current production methods to avoid this issue. If you're concerned, ask the seller specifically about the production date and whether the stone is guaranteed to stay colorless.
