No, moissanite does not develop intrinsic cloudiness. The crystal structure stays clear over time. If your stone ever looks dull, it is almost always surface film from oils, soap residue, or hard water deposits. A simple clean restores the sparkle. Let’s understand it deeper:
First, Let’s Clarify What “Cloudy” Means
People use the word in two ways, and that is where confusion starts.
1. Internal clouding
Permanent, within the stone. Cubic zirconia can show this as the material ages.
2. Surface haze
Temporary film from oils, soap, or minerals that blocks light until you clean it.
Actually, that difference matters more than any marketing claim. Internal clouding is a material problem. Surface haze is a care problem.
>Where Moissanite Stands?
Moissanite is silicon carbide. It is stable, tough, and ranks about 9.25 on the Mohs scale. It does not undergo the chemical changes that give CZ its long term haze. It also resists scratching better than most jewelry materials you touch daily.
So the stone itself does not cloud. What can happen is a film builds up on the surface and mutes the light until you clean it.
>Why Do Some Stones Look Dull With Time?
You might think a quick rinse fixes it. Rinsing helps, but residue often needs mild soap and gentle brushing to fully lift.
-
Skin oils and lotions: A thin film masks facet edges and reduces fire.
-
Soap residue: Hand soap and body wash can leave a sticky layer.
-
Hard water spots: Mineral deposits scatter light.
-
Metal wear: Scuffs on bezels and links can reduce perceived contrast even if the stone is fine.
A Cleaning Routine That Brings Back the Shine
You need: Warm water, 1 to 2 drops of mild dish soap, a very soft toothbrush, two clean microfiber cloths.
-
Make the bath: Warm, not hot.
-
Dry wipe first: Lift loose dust so you do not rub grit against the facets.
-
Light brush: Dip the brush, tap off excess, and use short, gentle strokes around the stones, prongs, and along the bezel or links.
-
Rinse with a damp cloth: Wipe away soap with plain water on a clean cloth. Do not submerge a watch unless the maker says immersion is safe.
-
Dry fully: Pat dry, then air dry face up. Finish with a clean microfiber to polish the face.
Good extras: A jewelry polishing cloth for metal. Skip abrasives and harsh dips.
>What You Should Avoid?
-
Bleach, ammonia, acetone, and chlorine. Tough on gaskets, platings, and adhesives.
-
Abrasive pastes and stiff brushes. They round edges and dull metal.
-
Hot water and steam at home. Heat can stress seals. Leave steam to a jeweler.
-
Ultrasonic machines on micro pavé. Useful for plain metal bracelets, risky for tiny stones.
Storage That Prevents Marks
You can keep pieces in separate soft pouches or a lined box so other jewelry cannot rub them. Also, you must avoid steamy bathrooms and direct sunlight on a dresser. For watches, we recommend you store face up so moisture can evaporate.
>Quick troubleshooting
Problem: My stone looks dull after a shower:
Solution: Soap film. Do the mild soap routine.
Problem: Speckled dots that will not wipe off dry
Solution: Hard water spots. Clean, then wipe with distilled water and dry.
Problem: One area still seems flat
Solution: Focus cleaning around prongs and the underside where residue hides.
Problem: Still not right after cleaning
Solution: Have a jeweler check for a loose stone or worn prong that is catching dirt.

>Watches, Rings, and Bracelets Have Extra Variables
For watches
Avoid pools and hot tubs. Chlorine roughs up gaskets and can leave residue. Keep crowns sealed. If you ever see fog inside the crystal, pause wear and get a pressure test.
For rings
A thin band makes the center look brighter, but it also collects more oils near the seat. Clean under the stone more often.
For bracelets
Links trap lotion. Work the brush along each link gap and around clasps, then dry well so water does not spot.
>Professional Care, Made Simple
A jeweler or watchmaker can do three helpful things in a short visit:
-
Clean with controlled tools and solutions.
-
Inspect prongs and screws for early movement.
-
Pressure test a watch case if rated for water resistance.
-
Think in 12 to 24 month intervals unless you are especially hard on your pieces.

Bottom Line
Moissanite does not get cloudy from the inside. If it looks off, it means the residue is sitting on the surface and blocking light.
You can clean it with mild soap and to protect it from harsh chemicals, we recommend you store it well. Do that and the fire you saw on day one will keep showing up years later.
