Moissanite vs. Cubic Zirconia: Which Is Better for Sparkle, Value & Durability?

Moissanite vs. Cubic Zirconia: The Key Differences Explained

If you’re looking for a diamond alternative, you’ve likely come across moissanite and cubic zirconia (CZ). While they might appear similar at a glance, the differences in sparkle, durability, and longevity are significant. Here’s a clear breakdown to help you make the best choice for your jewelry.

1. Brilliance and Sparkle – Which One Truly Shines?

Moissanite and cubic zirconia reflect light differently—and it shows.

Moissanite has a higher refractive index (2.65), producing unmatched brilliance and fire.
CZ has a lower refractive index (2.15), creating a glassier, flatter sparkle.
Moissanite mimics diamond fire more closely, while CZ can appear dull or overly white over time.

2. Durability – What Will Last Through Daily Life?

Jewelry should look beautiful and last. Here’s how the two compare.

Moissanite ranks 9.25 on the Mohs hardness scale—nearly as hard as a diamond.
Cubic zirconia scores 8–8.5, making it more prone to scratches and surface wear.
Moissanite withstands daily wear without clouding or chipping—perfect for everyday elegance.

3. Longevity – Will It Stay Sparkling Over Time?

When investing in fine jewelry, long-term beauty matters.

Moissanite maintains clarity and brilliance for life.
CZ often clouds or becomes scratched within a few years.
Moissanite’s durability makes it a lifetime gemstone, while CZ typically needs replacing.

4. Price – What’s the Smartest Investment?

Affordability is one thing. Value over time is another.

CZ is cheaper upfront but loses its luster quickly, often requiring replacement.
Moissanite is slightly more expensive but retains brilliance forever.
Moissanite offers premium quality without the diamond price tag—making it the better value long term.

5. Ethical Sourcing – Which Option Aligns With Your Values?

Both moissanite and CZ are lab-created and conflict-free, but not equal in quality.

Moissanite is sustainably lab-grown and known for premium craftsmanship.
CZ is also lab-created but lacks durability and lasting visual appeal.
Moissanite offers a more ethical and luxurious experience overall.
