Why Does Moissanite Sparkle More Than Diamond?
Moissanite often appears to sparkle more than diamonds because it has higher light dispersion, also known as “fire.”
This means moissanite reflects more rainbow-colored flashes of light compared to diamonds. In many lighting conditions, moissanite can appear brighter, more vibrant, and more reflective.
This does not necessarily make moissanite “better” or “worse” - it simply creates a different visual effect.
What Is “Fire” in a Gemstone?
In jewelry, fire refers to the colorful flashes of light you see when a gemstone reflects and separates light.
Moissanite has a higher refractive index and greater light dispersion than diamonds, which creates:
- stronger rainbow sparkle
- brighter flashes under lighting
- more dramatic brilliance
Diamonds, by comparison, tend to reflect more white light and often appear slightly softer or more subtle.
Does More Sparkle Mean Moissanite Looks Fake?
No - more sparkle does not mean fake.
Some people love moissanite because of its intense brilliance, while others prefer the softer sparkle of diamonds.
In real-world settings, most people simply notice:
- a bright gemstone
- strong brilliance
- luxurious appearance
The difference is usually only noticeable during close inspection or side-by-side comparison.
Why Does Moissanite Sometimes Look More “Rainbow”?
Because of its optical properties.
Moissanite naturally produces:
- colorful flashes under sunlight
- stronger rainbow reflections under LED lighting
- higher brilliance in bright environments
This effect is one reason many buyers intentionally choose moissanite.
Does Diamond Sparkle More Than Moissanite?

The answer depends on what type of sparkle you prefer.
Diamond:
- softer white brilliance
- classic luxury look

Moissanite:
- stronger sparkle
