Key Takeaways

• Moissanite's color and clarity are permanent.
• Dullness comes from residue on the surface, not from the stone itself.
• A 15 to 20 minute soak in warm, soapy water restores its sparkle.

Why Moissanite Stays Clear

Moissanite is silicon carbide, one of the most chemically stable and heat-resistant materials used in jewelry. It does not absorb water or oils, it does not react with everyday household products, and its hardness makes it very resistant to scratches. The brilliance you see on day one is the brilliance you will see for life.

So Why Might It Look Cloudy?

• Lotion and hand cream leave a film on the stone's surface.
• Soap residue builds up if you wash your hands while wearing your ring.
• Natural skin oils collect under the stone, where light enters.
• Dust and makeup settle into the setting over time.

Any of these can block light and make a stone look less bright. Because moissanite relies on light entering and bouncing back, even a thin film makes a visible difference.

What About Older Moissanite?

Some early moissanite made decades ago had a faint yellow or green tint from the start. That tint was part of the stone and never developed later. Modern growing methods now produce colorless stones graded D, E and F, which stay colorless.

How to Keep Moissanite Brilliant

1. Soak in warm water with a few drops of mild dish soap.
2. Brush gently with a soft toothbrush, especially behind the stone.
3. Rinse and pat dry with a lint-free cloth.

Frequently Asked Questions

Does moissanite get cloudy?

No. Moissanite itself does not become cloudy. A cloudy look comes from residue on the surface and disappears with cleaning.

Does moissanite change color over time?

No. The color of a moissanite is permanent. Modern colorless moissanite stays colorless.

Does moissanite scratch easily?

No. At 9.25 on the Mohs scale, moissanite is harder than almost every gem except diamond and is very scratch-resistant in daily wear.
