Moissanite is very hard and resistant to heat, which makes it easy to care for. Like any gem, it can look dull when oils and residue build up on its surface, and a simple clean brings back its fire.
How to clean it
- Soak the piece in warm water with a few drops of mild washing-up liquid for a few minutes.
- Brush gently with a soft toothbrush, especially under the stone.
- Rinse in a bowl of clean water and dry with a lint-free cloth.
Why moissanite can look hazy
A haze is almost always a film of residue: hand cream, soap, skin oils or hard-water deposits. It is not a change in the stone.
Think about the metal
The stone tolerates most cleaning methods, but its setting may not. Avoid chlorine and abrasive products on gold and silver, and use only gentle methods on plated metals. If the piece includes other gems, clean it according to the most delicate one.
How often
A quick clean every week or two keeps moissanite at its brightest, with a professional check of the setting from time to time for pieces worn every day.
Similar to diamond
Moissanite and diamond both attract oils, and both look their best when clean. The same routine works for both, and the same precautions apply to the metal and to any other stones in the piece.
Hard-water marks
If you notice spots after rinsing, they are usually mineral deposits from hard water. Rinse in filtered or bottled water and dry thoroughly with a lint-free cloth. Avoid acidic home remedies, which can harm some metals.
Storing moissanite
Moissanite is very hard and can scratch softer gems and metals if stored together. Keep each piece in its own compartment or pouch. Read How to store jewelry.
Check the setting
While cleaning, check that the stone does not move and that no prong catches on a cloth. Moissanite rarely needs anything beyond cleaning; the setting is what benefits from regular attention.
Gold-plated or silver settings
If a moissanite piece is set in plated metal or sterling silver, clean it gently with warm soapy water and a soft cloth. Avoid polishing cloths and abrasive products that can wear through plating.

Frequently asked questions
Does moissanite get cloudy permanently?
No. A cloudy look comes from residue on the surface; cleaning removes it.
Can moissanite go in an ultrasonic cleaner?
Moissanite itself tolerates it, but the setting and any other stones may not. When in doubt, use warm soapy water.
How do I remove spots from moissanite?
Rinse in filtered water, dry with a lint-free cloth, and avoid acidic cleaners.
Can I clean moissanite with a jewelry cleaner?
Yes, if the cleaner is suitable for the metal and any other stones in the piece.
