Short Answer:
❌ No — moissanite does not naturally become cloudy over time. ✔ “Cloudiness” comes from poor cutting, crushed-ice styles, oil buildup, or low-quality material.

“Cloudy moissanite” is one of the most misunderstood topics in the gemstone world. The confusion comes from mixing together cut style issues, maintenance, and vendor quality.
1. Can moissanite become cloudy with age?
No. Moissanite is extremely hard (9.25 Mohs) and chemically stable. It does not:
- degrade,
- oxidize,
- develop internal haze over time.
If a stone looks cloudy, it was cut or sourced poorly — not “aged.”
2. The real causes of “cloudy” moissanite
- Crushed-ice cutting: tiny facets scatter light unevenly
- Low-quality rough: microscopic inclusions create haze
- Oil & lotion buildup: affects all gemstones
- Poor polish: reduces light return
3. Crushed ice vs brilliant (cloudiness risk)
| Cut Style | Cloudiness Risk | Clarity Appearance |
|---|---|---|
| Brilliant | Low | Sharp & clear |
| Crushed Ice | Medium–High | Soft / hazy if poorly cut |
This is why crushed-ice moissanite must come from a trusted vendor.
4. Oil slick vs true cloudiness
Many buyers mistake surface buildup for internal cloudiness.
- hand lotion,
- soap residue,
- skin oils.
A quick clean restores full brilliance.
5. How to help ensure a clear moissanite
- Choose brilliant or hybrid cuts
- Avoid ultra-cheap crushed-ice stones
- Stick to vetted vendors
- Clean monthly with warm water + dish soap
Clear moissanite is the norm — cloudy moissanite is a sourcing failure.
6. Final verdict
Moissanite does not become cloudy over time. What buyers call “cloudy” is almost always:
- poor cutting,
- poor material,
- or poor maintenance.
Next Steps:
- Choose the right cut using the Brilliant vs Crushed Ice Guide.
- Compare trusted vendors in the Vendor Directory.
- Calculate value with the Moissanite Savings Calculator.
Moissanite clarity is permanent — bad decisions are optional.
