The Short Answer: No
Moissanite does not lose its brilliance, get cloudy, or fade over time. Its optical properties are permanent and stable, ensuring your jewellery maintains its fire and sparkle for a lifetime—and beyond.
Why Moissanite Stays Brilliant Forever
Moissanite's crystal structure is exceptionally stable. Unlike some gemstones that can develop internal fractures, cloudiness, or colour changes with age, moissanite's silicon carbide composition remains unchanged regardless of time, wear, or environmental exposure.
The Science Behind Permanent Sparkle
Moissanite's refractive index (2.65) and dispersion (0.104) are intrinsic properties of the material itself, not surface treatments or coatings that can wear away. These optical characteristics are built into the atomic structure and cannot diminish.
What About That Cloudy Film?
If your moissanite appears cloudy or dull, it's not the stone—it's surface buildup from:
- Lotions, soaps, and cosmetics
- Natural skin oils
- Household cleaning products
- Environmental dust and debris
This film sits on top of the stone and wipes away easily with proper cleaning. The moissanite underneath remains perfectly brilliant.
Comparison to Other Gemstones
Unlike cubic zirconia, which can become cloudy and lose sparkle within months of wear, moissanite maintains its optical performance indefinitely. Unlike some treated diamonds or gemstones with surface coatings, moissanite requires no special care to preserve its appearance.
Decades of Proven Performance
Moissanite has been used in jewellery since the 1990s. Pieces from that era still exhibit the same brilliance as newly created stones, providing real-world proof of moissanite's permanent sparkle.
Your Lifetime Guarantee
Quality moissanite jewellery comes with lifetime warranties covering the stone's optical performance. Manufacturers can confidently offer these guarantees because moissanite simply doesn't degrade.
Maintaining That Sparkle
Regular cleaning removes surface buildup and keeps your moissanite looking its absolute best. A quick clean every few weeks ensures maximum brilliance—but even neglected moissanite will sparkle brilliantly once cleaned.
