Now, let’s get started—myth #7 might surprise you!
Myth 1: Moissanite Is Just a Fake Diamond
One of the biggest misconceptions about moissanite is that it’s just an imitation diamond, no different from cubic zirconia or other cheap diamond simulants. But that couldn’t be further from the truth.
Reality Check: Moissanite Is a Unique Gemstone
Moissanite isn’t a knockoff—it’s a completely separate gemstone with its own distinct chemical structure, optical properties, and durability. Originally discovered in a meteorite crater by Henri Moissan in 1893, this mineral (silicon carbide) is exceptionally rare in nature. Today, all moissanite used in jewelry is lab-created, ensuring ethical sourcing and top-tier quality.
What Makes Moissanite Different from Diamonds?
- Brilliance & Fire – Moissanite actually reflects more light than diamonds, giving it an ultra-sparkly appearance.
- Durability – Scoring 9.25 on the Mohs scale, moissanite is one of the hardest gemstones, making it highly resistant to scratches.
- Ethical & Affordable – Unlike mined diamonds, moissanite is a conflict-free and cost-effective alternative.

Myth 2: Moissanite Will Turn Cloudy Over Time
A common concern among buyers is whether moissanite will lose its brilliance or turn cloudy as it ages. Some assume it behaves like cubic zirconia, which can become dull over time. But is this really true?
Reality Check: Moissanite Stays Brilliant Forever
Moissanite does not get cloudy or lose its sparkle over time. Its chemical composition—silicon carbide—ensures it remains permanently clear and brilliant. Unlike some gemstones that absorb oils or moisture, moissanite is highly resistant to dirt buildup and does not degrade with wear.
Why Does This Myth Exist?
As you can see the above picture, if you are too unlucky to get bad moissanite, it can become cloudy! But this kind of incident are very rare and surely Moissanite is great choice. Fun fact, Diamonds can become cloudy too!
- Some low-quality diamond simulants, like cubic zirconia, scratch easily and develop a cloudy appearance over time. Moissanite, on the other hand, scores 9.25 on the Mohs hardness scale, making it incredibly scratch-resistant.
- Buildup from everyday wear—such as lotion, soap, or natural skin oils—can temporarily dull any gemstone, including moissanite. However, a simple cleaning routine restores its shine effortlessly.
How to Keep Moissanite Sparkling
- Clean regularly with warm water, mild soap, and a soft brush.
- Avoid harsh chemicals like bleach or chlorine.
- Use an ultrasonic cleaner for deep cleaning when needed.
Moissanite’s brilliance is permanent, making it a lasting choice for engagement rings and fine jewelry. Learn more in this detailed guide on whether moissanite gets cloudy.
Myth 3: Moissanite Looks Cheap and Fake
Some people assume moissanite is just a “cheap” alternative to diamonds and lacks the elegance of fine jewelry. But is that really the case?
Reality: Moissanite Is a Luxury Gemstone with Superior Sparkle
Moissanite is anything but cheap-looking. In fact, it has higher brilliance and fire than diamonds, meaning it reflects more light and creates a more intense sparkle. The reason for this is its high refractive index (2.65–2.69), which exceeds that of diamonds (2.42).
Fact-Check: It’s All About Preference, Not Quality
- Some people love the extra sparkle. Moissanite has a rainbow-like fire that makes it stand out.
- Others prefer a more subtle glow. Diamonds have a classic white light return, which some consider more traditional.
- High-end jewelers use moissanite. It’s set in luxury jewelry pieces, proving its value.
Moissanite in Fine Jewelry
Many buyers now choose moissanite bracelets and moissanite necklaces as affordable yet elegant jewelry pieces. These aren’t “cheap” accessories—they offer high-end beauty at a fraction of the cost.

Myth 4: Everyone Will Know It’s Not a Diamond
Some people worry that moissanite is easy to spot and that others will immediately recognize it as a diamond alternative. But is that really true?
Reality: Moissanite Is Nearly Indistinguishable from Diamonds
To the naked eye, moissanite looks almost identical to a diamond—especially in sizes under 1.5 carats. Even larger moissanite stones resemble high-quality diamonds, though they may have slightly more fire (rainbow flashes).
Fact-Check: Only Experts Can Tell the Difference
- Most people can’t distinguish them. Without magnification, moissanite and diamonds appear very similar.
- Trained gemologists use special tools. A jeweler may spot moissanite’s double refraction under a loupe, but the average person won’t.
- Side-by-side comparisons are tricky. Even when placed next to diamonds, moissanite holds its own in terms of brilliance and sparkle.

Myth 5: Moissanite Is Not as Durable as Diamond
Many people assume that because diamonds are the hardest natural material, moissanite must be significantly less durable. But is this really the case?
Reality: Moissanite Is One of the Hardest and Most Durable Gemstones
While diamonds rank 10 on the Mohs hardness scale, moissanite comes very close at 9.25. This makes it extremely scratch-resistant and suitable for daily wear—just like diamonds.
Fact-Check: Moissanite Can Withstand Daily Use with Ease
- Scratch Resistance: Only a few materials, like diamonds and sapphires, are harder than moissanite.
- Heat Resistance: Moissanite withstands high temperatures without damage, unlike other diamond alternatives.
- Durability: It’s tough enough for engagement rings, wedding bands, and heirloom jewelry.
Durability Comparison: Moissanite vs. Diamond vs. Other Stones
| Gemstone | Mohs Hardness | Scratch Resistance | Heat Resistance | Ideal for Daily Wear? |
|---|---|---|---|---|
| Diamond | 10 | ⭐⭐⭐⭐⭐ (Highest) | ⭐⭐⭐⭐⭐ (Highest) | ✅ Yes |
| Moissanite | 9.25 | ⭐⭐⭐⭐☆ (Very High) | ⭐⭐⭐⭐⭐ (Highest) | ✅ Yes |
| Sapphire | 9 | ⭐⭐⭐⭐☆ (High) | ⭐⭐⭐⭐☆ (High) | ✅ Yes |
| Cubic Zirconia | 8-8.5 | ⭐⭐⭐☆☆ (Moderate) | ⭐⭐⭐☆☆ (Moderate) | ❌ No (Prone to Scratches) |

Myth 6: Moissanite Has No Resale Value
A common argument against moissanite is that it has little to no resale value. But how true is this when compared to diamonds?
Reality: Diamonds Also Depreciate in Value
While it’s true that moissanite isn’t typically resold for a high price, the same applies to most retail diamonds. In fact, the resale market for diamonds is not as strong as many people assume.
Fact-Check: The Resale Value of Moissanite vs. Diamonds
- Diamonds lose 30-50% of their value immediately after purchase unless they are rare, investment-grade stones.
- Moissanite is not marketed as an investment gemstone, so its lower resale value is expected.
- Both stones are better viewed as personal jewelry choices rather than financial assets.
Resale Value Comparison: Moissanite vs. Diamond
| Gemstone | Retail Price Retention | Common Resale Percentage | Market Demand |
|---|---|---|---|
| Diamond | 50-70% lost after purchase | 20-50% of original price | High, but only for top-tier stones |
| Moissanite | Lower initial price | Typically resells for less than 20% | Moderate (for high-quality stones) |
| Cubic Zirconia | No resale value | Negligible | Low |
The Takeaway: Buy Jewelry for Love, Not for Resale
Instead of worrying about resale value, choose a gemstone that fits your budget, style, and ethical preferences.

Myth 7: Moissanite Changes Color Over Time
One of the biggest misconceptions about moissanite is that it will turn yellow, green, or cloudy as it ages. This myth likely stems from older, lower-quality moissanite.
Reality: Modern Moissanite Stays Colorless and Stable
- High-quality moissanite today is graded D-F in color, meaning it appears just as colorless as top-tier diamonds.
- It does not oxidize, fade, or develop a yellow/green tint over time.
- Some early moissanite (pre-2015) had slight warmth, but modern moissanite is engineered for permanent color stability.
Fact-Check: What Affects Moissanite’s Appearance?
- Lighting Conditions – Like diamonds, moissanite can reflect different hues depending on the light source. Learn more about how moissanite reacts under UV light and sunlight.
- Low-Quality Moissanite – Greenish moissanite is rare but can happen with certain treated moissanite stones.
- Coated or Imitation Stones – Some sellers coat moissanite to imitate fancy colors, but this isn’t natural moissanite. If you’re looking for something unique, you might prefer black moissanite.
Moissanite will never change color over time as long as it’s genuine and high-quality. If color change happens, it’s either due to dirt buildup or an artificially treated stone.
Myth 8: Moissanite Can’t Be Certified Like Diamonds
Many believe that moissanite isn’t certified or graded like diamonds, leading to doubts about its authenticity. However, this is a misunderstanding of how gemstone certification works.
Reality: Moissanite Can Be Certified, But the Standards Differ
- Diamonds are graded by GIA (Gemological Institute of America) based on the 4Cs—cut, color, clarity, and carat weight.
- Moissanite is certified by GRA (Gemological Research Association) but isn’t graded on the same scale as diamonds.
- Moissanite is almost always internally flawless, so clarity grading isn’t as relevant as it is for diamonds.
Fact-Check: What Does Moissanite Certification Cover?
- GRA certification confirms that a stone is moissanite, ensuring buyers aren’t getting a mislabeled diamond simulant. If you’re purchasing a GRA-certified moissanite ring, it guarantees authenticity.
- Unlike diamonds, moissanite isn’t judged by the 4Cs in the same way. However, its cut, color, and clarity still impact its beauty.
Moissanite can be certified, but it follows a different system from diamonds. If you’re buying moissanite, look for GRA or another reputable gem lab certification to ensure quality and authenticity.
Myth 9: Moissanite Is Not Ethical or Sustainable
One common myth about moissanite is that it’s not an ethical choice, especially when compared to diamonds. Many people assume that all gemstones have a questionable impact on the environment and communities. Let’s break down this misconception.
Reality: Moissanite Is 100% Ethical and Sustainable
- Moissanite is lab-created, which means it has no environmental impact from mining, unlike diamonds that often involve destructive mining practices.
- Conflict-Free: Moissanite is not associated with conflict or blood diamonds, as it’s not mined.
Fact-Check: Why Moissanite Is a Better Ethical Choice
- Moissanite vs. Diamond: Diamonds are sometimes referred to as conflict materials due to the unethical practices in mining. Moissanite, on the other hand, is produced in a lab, eliminating these concerns entirely.
- Conflict Materials: While diamonds are linked to violence and exploitation in certain regions, moissanite is 100% eco-friendly, cruelty-free, and sustainable.
- Where Moissanite Comes From: Since moissanite is lab-grown, there is no mining involved, meaning it doesn’t contribute to environmental degradation.
Moissanite is one of the most ethical and sustainable choices you can make when purchasing gemstones. It’s conflict-free, environmentally friendly, and ethically produced—perfect for those who want luxury without the negative impact.
Myth 10: Moissanite Will Go Out of Style
As moissanite continues to rise in popularity, some still question whether it will be a passing trend. Let’s explore why this myth doesn’t hold up.
Reality: Moissanite Is Here to Stay
