Does Moissanite Lose Its Sparkle?

Does Moissanite Lose Its Sparkle?

If you’re considering moissanite for an engagement ring or fine jewelry, one of the most common questions is: will it stay as brilliant over time?
The short answer is no—moissanite does not lose its sparkle permanently. But there’s a little more nuance worth understanding.

Why Moissanite Is So Sparkly

Moissanite is known for its intense brilliance and fire (those rainbow flashes you see in light). This comes from its high refractive index, which is actually higher than a diamond.

That means:

  • More light enters the stone
  • More light reflects back to your eyes
  • Result = exceptional sparkle, even in low light

Does the Sparkle Fade Over Time?

No, moissanite doesn’t dull or lose its brilliance with age.

Unlike some gemstones, moissanite:

  • Does not cloud internally
  • Does not fade in color
  • Does not wear down easily (it ranks 9.25 on the Mohs hardness scale)

So structurally and optically, your stone remains just as brilliant years later.

Why It Might Look Less Sparkly Sometimes

If your moissanite ever looks dull, it’s almost always due to surface buildup, not the stone itself.

Common causes:

  • Oils from skin
  • Lotion or makeup residue
  • Soap film
  • Dust and daily grime

These create a thin layer on the surface that blocks light from entering and reflecting properly.

How to Restore the Sparkle

Good news: bringing back that shine is very easy.

Simple at-home cleaning:

  1. Soak in warm water with mild soap
  2. Gently brush with a soft toothbrush
  3. Rinse and dry with a lint-free cloth

After cleaning, you’ll see your moissanite return to its full brilliance instantly.

Will It Ever Turn Cloudy or Yellow?

No—high-quality moissanite is designed to remain:

  • Clear
  • Color-stable
  • Brilliant for life

Unlike older, low-quality stones, modern moissanite (especially from reputable brands) does not develop cloudiness over time.

Moissanite vs Diamond Sparkle

  • Moissanite → More fire (rainbow flashes), extra sparkle
  • Diamond → More white light brilliance, subtler shimmer

So if anything, moissanite tends to look more sparkly—not less.
