When choosing between diamonds and moissanite, sparkle often becomes the deciding factor. Which is more sparkly diamond or moissanite? Let’s explore how their brilliance compares and why one might stand out as the ultimate choice for you.
Sparkle Showdown: Which Is More Sparkly Diamond or Moissanite?
The sparkle of a gemstone is primarily determined by its refractive index (RI) and dispersion, which affect how light is bent and split into colors. Here’s how diamonds and moissanite stack up:
- Diamonds: With an RI of 2.42, diamonds produce a natural, classic brilliance that is more subtle and white in appearance. Their fire (color dispersion) is elegant but less vivid.
- Moissanite: Boasting an RI of 2.65-2.69, moissanite outshines diamonds with superior brilliance. Its fiery dispersion is nearly 2.5 times greater, resulting in more vibrant flashes of rainbow-like colors.
The sparkle of a gemstone is determined by two key factors:
- Refractive Index (RI): Measures how much light is bent as it enters the gemstone.
- Dispersion: Measures how much white light is split into rainbow colors (fire).
Here’s how diamonds and moissanite compare:
| Gemstone | Refractive Index (RI) | Dispersion (Fire) |
|---|---|---|
| Diamond | 2.42 | 0.044 |
| Moissanite | 2.65-2.69 | 0.104 |
Example Calculation:
Let’s calculate the relative brilliance and fire of moissanite compared to diamond:
Brilliance (proportional to RI):
Brilliance (proportional to RI):
Moissanite Brilliance Factor = 2.67 ÷ 2.42 ≈ 1.10
Moissanite is about 10% more brilliant than diamond.
Fire (proportional to Dispersion):
Moissanite Fire Factor = 0.104 ÷ 0.044 ≈ 2.36
Moissanite produces over 2.3 times more fire than diamond.
Moissanite produces over 2.3 times more fire than diamond, leading to more vibrant rainbow-like flashes.
Why Does Moissanite Sparkle More Than a Diamond?
Moissanite’s unique crystal structure enhances its ability to refract light, making it appear more sparkly in both natural and artificial light. Additionally, its precision cutting—such as the ideal hearts and arrows cut—ensures maximum sparkle.

The Verdict: Which Should You Choose?
If you prefer a gemstone with a timeless, understated elegance, a diamond might be your best choice. However, if dazzling brilliance and affordability are your priorities, moissanite is the clear winner.
