Is Moissanite Resistant to Scratching and Chipping?

The Moissanite Marvel

Moissanite, hailed as the gem of the stars, has risen in popularity over recent years. Its shimmering allure, combined with its practical benefits, has made it a favorite among jewelry enthusiasts. A critical question on everyone's mind is its resistance to wear and tear: Can this celestial gem withstand scratches and chipping?

Understanding Moissanite's Structure

Before diving deep into its durability, understanding moissanite's crystalline structure is paramount. Comprising Silicon Carbide (SiC), moissanite boasts a unique molecular arrangement, laying the foundation for its strength.

Moissanite and the Mohs Hardness Scale

The Mohs scale, universally accepted to gauge mineral hardness, ranks moissanite at an impressive 9.25. This places it just below diamonds, which sit at a perfect 10. It's evident that moissanite is significantly resistant to scratches.

Chipping Concerns: How Does Moissanite Fare?

While moissanite's hardness is commendable, hardness and toughness are distinct. The latter pertains to a gem's resistance to breakage or chipping. Thankfully, moissanite's exceptional crystalline structure ensures it exhibits good toughness.

Comparing Moissanite to Other Popular Gems

Positioning moissanite against popular counterparts offers a comprehensive perspective on its durability.

Moissanite vs. Diamond

Diamonds, nature's hardest substance, are undoubtedly scratch-resistant. However, their cleavage planes make them susceptible to chipping. Moissanite, lacking such cleavage, offers enhanced resistance to chipping in specific scenarios.

Moissanite vs. Sapphires

Sapphires, ranking 9 on the Mohs scale, are slightly softer than moissanite. Though both gems display commendable scratch resistance, moissanite edges out with its higher ranking and structural integrity.

Moissanite vs. Cubic Zirconia

Cubic Zirconia, with a Mohs rating of 8, scratches more easily than moissanite. Additionally, CZ's propensity to chip under stress makes moissanite a clear winner in the durability department.

Practical Tips: Caring for Your Moissanite Jewelry

No gem, irrespective of its durability, is invincible. Here are a few tips to ensure your moissanite retains its brilliance:

  1. Routine Cleaning: A gentle wash with lukewarm water and mild soap keeps your moissanite gleaming.
  2. Storage: Store moissanite jewelry separately to prevent potential scratches from other pieces.
  3. Professional Check-ups: Periodic inspections by professionals can identify and rectify potential issues.

In Conclusion

Moissanite, a gem of celestial origin, impressively stands its ground against scratches and chipping. While no gemstone is impervious to all potential harm, with proper care, moissanite promises a lifetime of shimmering splendor.


  1. How often should I get my moissanite jewelry inspected?
    • Annual professional inspections are advisable for ensuring the gem's longevity.
  2. Can I wear moissanite daily without it getting scratched?
