Moissanite does not naturally get cloudy, and its brilliance is designed to last for decades with proper care. Any appearance of dullness or haziness is almost always caused by surface factors such as dirt, oils, residue, or minor scratches rather than flaws in the stone itself.
Understanding what triggers moissanite cloudiness, how to spot it early, and the most effective ways to clean and maintain the stone is essential for preserving its fire and sparkle.
Here, you will know the most common causes of cloudiness, step-by-step cleaning techniques, preventive measures, and situations where professional care may be needed so that your moissanite continues to shine like the day it was first worn.
Key Takeaways
-
True internal cloudiness in moissanite is extremely rare, with most dullness resulting from surface buildup or minor scratches.
-
Dirt, oils, residue, and exposure to harsh chemicals are the main contributors to temporary moissanite cloudiness.
-
Consistent cleaning and proper handling are essential to maintain brilliance and prevent the gemstone from appearing dull.
-
Micro-scratches or surface wear can slightly reduce sparkle, but these issues are often reversible through professional polishing.
-
With regular care and preventive maintenance, moissanite retains its fire and shine for decades without permanent dulling.
Common Causes of Moissanite Cloudiness
Moissanite is highly durable, but its sparkle can diminish if the gemstone is exposed to certain environmental factors or improper care. The most common reasons for cloudiness are dirt, oils, residue, micro-scratches, and chemical exposure.

Daily wear naturally transfers oils from skin, lotion, and makeup to the surface of the stone, forming a thin layer that scatters light and makes the gemstone appear dull. Similarly, dust and airborne debris can accumulate in the setting or on the facets, reducing the gem’s brilliance.
Micro-scratches from incidental contact with other jewelry or rough surfaces can subtly scatter light, leading to a slightly muted sparkle. Harsh cleaning chemicals, including bleach, ammonia, or abrasive cleaners, can also leave a film or damage the surface, creating cloudiness that is more persistent.
Understanding these factors is essential to maintaining the stone’s visual integrity.

How to Identify Moissanite Cloudiness
Identifying cloudiness in moissanite is not always obvious, especially for people unfamiliar with the stone’s natural sparkle. Cloudiness generally presents as a hazy or muted appearance where the gemstone loses its characteristic fire and brilliance.

Common indicators include dull or muted reflection of light, foggy areas near the prongs or crevices, and lack of sharp flashes of rainbow-colored light. Unlike permanent damage, surface-related cloudiness often appears unevenly, concentrated in areas where oils, dust, or dirt are trapped.
A simple test is to place the moissanite under bright light and observe whether the light reflects sharply from its facets. If the sparkle is diminished and flashes of color are weak, it is a sign that the stone requires cleaning or minor polishing. Early identification ensures that temporary cloudiness does not progress into more noticeable dulling over time.

Cleaning and Maintaining Moissanite Sparkle
Proper cleaning and care are essential to prevent moissanite from appearing cloudy. The most effective and safe method is soaking the gemstone in warm water with a few drops of mild dish soap for 10-15 minutes, then gently scrubbing with a soft-bristled brush.
Rinse thoroughly to remove any soap residue and dry with a lint-free cloth. For stubborn debris, ultrasonic cleaners may be used, but only if the stone is securely set in the jewelry. Professional jewellers can polish minor surface scratches that reduce brilliance.
Preventive measures, such as wiping the stone regularly after wearing and avoiding harsh chemicals, are equally important. Consistent care ensures that moissanite maintains its radiant sparkle, even with daily use, and prevents the small buildup of residues that often leads to temporary cloudiness.

Preventing Moissanite Cloudiness
Preventing cloudiness is more effective than fixing it after it appears. Simple habits can significantly prolong the stone’s shine. Always remove moissanite jewelry before handling harsh chemicals or cleaning agents.
Avoid rough surfaces and accidental knocks that may cause micro-scratches. Store jewelry separately to prevent contact with other pieces. Periodic inspections by a professional jeweller can ensure that prongs and settings are intact, preventing dirt accumulation in crevices.
Maintaining consistent cleaning routines, such as weekly washing and daily wiping, also reduces the likelihood of surface buildup. By combining these preventive measures, moissanite can retain its fire, brilliance, and clarity, remaining virtually indistinguishable from the day it was first worn.
When Cloudiness Becomes Permanent
While rare, permanent cloudiness in moissanite can occur under extreme conditions. Deep scratches, internal fractures from heavy impact, or prolonged exposure to harsh chemicals can cause irreversible dulling.
Signs of permanent cloudiness include visible surface abrasions affecting light reflection, internal haze that cannot be removed through cleaning, and overall loss of the stone’s natural fire. If permanent damage occurs, options include professional polishing for surface issues or, in extreme cases, replacing the stone.
Despite this, most moissanite cloudiness remains temporary, and with proper care, the gemstone maintains its radiant sparkle for decades.
Conclusion
Moissanite is a durable, fire-filled gemstone that rarely develops true cloudiness. Most instances of dullness or haziness are surface-related, caused by oils, dirt, micro-scratches, or chemical exposure.
Even the most durable gemstones can lose a bit of their sparkle over time, which is why choosing the right jewelry matters. Our moissanite rings, necklaces, earrings, and pendants are carefully crafted to highlight moissanite’s fire while making cleaning and care effortless.
By identifying early signs of cloudiness, using safe cleaning techniques, and following preventive care habits, moissanite can retain its brilliance and sparkle for a lifetime. Permanent cloudiness is extremely rare, making moissanite an ideal choice for jewelry that continues to shine without significant maintenance.
Regular care, mindful wear, and professional checkups are all that’s needed to ensure that each piece remains as radiant as the day it was first set.
FAQs About Moissanite Cloudiness
What causes moissanite to look cloudy?
Cloudiness is usually caused by surface buildup like dirt, oils, lotion, dust, or residue. Micro-scratches and harsh chemicals can also temporarily reduce sparkle.
How can I tell if moissanite’s cloudiness is temporary or permanent?
Temporary cloudiness clears with gentle cleaning or polishing. Permanent cloudiness is rare and shows as internal haze or deep scratches that don’t improve.
Can cleaning remove cloudiness from moissanite?
Yes. Soaking in warm water with mild soap and gently brushing removes oils, dirt, and residue, restoring the stone’s sparkle.
How does everyday wear affect moissanite’s clarity?
Daily exposure to lotions, oils, sweat, or dust can create a thin film, causing temporary cloudiness. Regular wiping and cleaning prevent buildup.
When should I seek professional help for cloudy moissanite?
If cloudiness persists after cleaning, appears uneven, or is accompanied by scratches, a jeweller can polish or inspect the stone to restore its brilliance.
