Does Moissanite Get Cloudy Over Time?

by Lisa Jewelry US 0 comments

When you invest in a beautiful piece of jewelry, whether it’s an engagement ring, a special gift, or a treasured self-purchase, you naturally want it to maintain its brilliance for a lifetime. Among the many sparkling options available today, Moissanite has become a popular choice, beloved for its incredible fire, durability, and ethical sourcing. However, one common concern still lingers: Does Moissanite get cloudy over time?

It’s a valid question, especially considering that some other gemstones can lose their luster with age or improper care. No one wants to see their once-sparkling gem turn dull and lifeless. In this article, we’ll dive deep into the truth behind this concern, explore what makes Moissanite unique, and share expert tips on how to keep your stone shining as brilliantly as the day you first wore it.

I. What Is Moissanite?

Moissanite is a truly remarkable gemstone with an almost cosmic origin story. It was first discovered in 1893 by French scientist Henri Moissan while examining rock samples from a meteor crater in Arizona. At first, he believed he had found diamonds, but later realized the crystals were composed of silicon carbide — a completely different material. Because natural Moissanite is incredibly rare on Earth, the Moissanite used in jewelry today is grown in sophisticated laboratory environments, making it both accessible and eco-friendly.

What sets Moissanite apart from other gemstones is its exceptional optical properties. Thanks to its unique composition, Moissanite exhibits a brilliance and fire that surpasses even that of a diamond. Brilliance refers to the white light reflected from a gem, while fire describes the colorful flashes of light that appear when the gem catches the light. Moissanite’s refractive index is higher than that of diamonds, meaning it bends light more effectively, creating that unmistakable, rainbow-like sparkle that so many people adore.

In addition to its dazzling beauty, Moissanite is incredibly durable. On the Mohs scale of hardness, which measures a mineral’s resistance to scratching, Moissanite ranks at an impressive 9.25 out of 10. This makes it one of the hardest known substances, second only to diamonds. As a result, Moissanite is an excellent choice for everyday jewelry like engagement rings and earrings, able to withstand the rigors of daily life without losing its stunning appearance.

II. Does Moissanite Get Cloudy?

One of the biggest myths surrounding Moissanite is that it becomes cloudy over time. The truth is reassuring: Moissanite does not naturally become cloudy as it ages. Unlike some other gemstones that can chemically degrade or lose clarity with exposure to air, moisture, or light, Moissanite is remarkably stable. Its strong crystal structure and chemical composition resist the environmental factors that can cause lesser stones to deteriorate.

So where does this misconception come from? Often, what people interpret as “cloudiness” is actually the result of a surface issue rather than a flaw within the gemstone itself. Over time, jewelry is exposed to everyday substances like oils from your skin, lotions, soaps, cosmetics, and household cleaning agents. These substances can build up on the surface of a Moissanite, creating a filmy layer that dulls its sparkle. However, this buildup is external and temporary — it does not indicate any damage or permanent change to the stone.

Imagine looking through a window after a rainstorm. The glass might appear cloudy or dirty, but a simple cleaning will restore its transparency. The same principle applies to Moissanite. A quick and gentle cleaning can easily remove the residues and restore the gem’s brilliance to its original, breathtaking state.

Another factor to consider is water quality. In areas with hard water — water that contains high levels of minerals like calcium and magnesium — jewelry can accumulate mineral deposits more quickly. If not cleaned regularly, these deposits can create a dull appearance on any gemstone, including Moissanite. Again, this is a surface phenomenon, not a defect within the stone.

In extremely rare cases, improper cleaning methods might contribute to a temporary reduction in sparkle. For example, using harsh chemicals, ultrasonic cleaners, or abrasive brushes not intended for fine jewelry could cause micro-scratches on the surface of the setting (particularly if it’s gold or platinum), which may reflect light differently. However, when it comes to the Moissanite itself, its hardness and resilience protect it from these kinds of damages far better than most other gemstones.

In short, Moissanite remains internally brilliant and stable over time. If a Moissanite stone appears cloudy, the problem lies on the surface and can almost always be corrected with proper care and cleaning — not with any flaw in the stone itself.

III. Why Some Moissanite Stones May Appear Dull

While Moissanite itself does not lose its brilliance or become cloudy internally, there are several common external factors that can temporarily diminish its sparkle. Understanding these causes will help you better care for your jewelry and ensure that your Moissanite pieces continue to radiate their signature fire and brilliance.

1. Accumulation of Oils and Lotions

One of the most frequent culprits behind a dull-looking Moissanite is the everyday buildup of natural skin oils, lotions, perfumes, and makeup. As you wear your jewelry throughout the day, tiny particles can settle on the surface of the stone. Over time, these residues can create a thin film that scatters light instead of allowing it to pass cleanly through the gem, making it appear less vibrant.

Although these residues are invisible at first, they can accumulate to the point where they noticeably affect the gemstone’s appearance. Fortunately, regular and gentle cleaning can easily remove these layers and restore your Moissanite’s stunning brilliance.

2. Hard Water Deposits

If you frequently expose your jewelry to water, particularly in areas with hard water, mineral deposits can form on the surface of your Moissanite. Hard water contains high levels of minerals such as calcium and magnesium, which can leave behind a chalky residue after evaporation. These mineral deposits can create a cloudy or spotted appearance on the gemstone.

Washing hands, showering, or doing household chores while wearing your jewelry can all contribute to this buildup. However, this is a surface issue only and can be effectively treated with proper cleaning techniques, ensuring that your stone looks as radiant as ever.

3. Inadequate Cleaning Practices

While cleaning is essential, using the wrong methods or products can actually cause more harm than good. Harsh chemicals, abrasive cleaners, or rough scrubbing tools can damage the metal settings around the Moissanite or leave tiny scratches that interfere with the overall sparkle. Although Moissanite itself is highly resistant to scratching, the setting materials, such as gold or silver, are often softer and more vulnerable.

Using gentle, non-abrasive methods — like a soft toothbrush with mild dish soap — is the safest and most effective way to clean Moissanite jewelry without risking damage to the piece.

4. Environmental Exposure

Certain environments can also impact the appearance of your jewelry temporarily. Activities like swimming in chlorinated pools, gardening, cooking, or working with chemicals can expose your jewelry to substances that cause buildup or temporary dullness. Even airborne dust and pollutants can settle on jewelry over time.

To minimize exposure, it’s a good practice to remove your Moissanite pieces when engaging in activities that could subject them to harsh conditions. Proper storage when not in use — such as keeping your jewelry in a clean, dry, and soft-lined box — will also help preserve its brilliance.

III. How to Properly Care for Moissanite

Maintaining the breathtaking sparkle of your Moissanite jewelry is simpler than you might think. With a few easy habits and some gentle care, you can ensure that your jewelry remains as brilliant as the day you first wore it.

1. Regular Cleaning at Home

The most effective way to keep your Moissanite gleaming is regular, gentle cleaning. Here’s a simple routine you can follow at home:

Prepare a Cleaning Solution: Mix a few drops of mild dish soap with warm (not hot) water in a small bowl.

Soak Your Jewelry: Place your Moissanite jewelry in the solution and let it soak for about 10–15 minutes. This loosens any oils, dirt, or residues.

Gently Brush: Use a soft-bristled toothbrush — ideally one designated solely for your jewelry — to lightly scrub the stone and setting. Pay extra attention to areas behind the stone where buildup often hides.

Rinse Thoroughly: After brushing, rinse your jewelry under warm running water to wash away any soap residue.

Dry and Polish: Pat dry with a lint-free cloth and, if desired, gently polish the stone for extra sparkle.

By incorporating this cleaning routine once every couple of weeks — or more often if you wear the piece daily — you can easily keep your Moissanite radiant.

2. Professional Cleanings

While home care is usually sufficient, it’s a good idea to have your jewelry professionally cleaned once or twice a year. Professional jewelers have specialized tools and solutions that can reach into tiny crevices, ensuring a thorough cleaning that restores your jewelry to its maximum brilliance. During a professional cleaning, they can also inspect the setting to make sure everything is secure and in good condition.

3. Smart Wearing Habits

Practicing a few smart habits when wearing your Moissanite jewelry can help minimize exposure to dirt and chemicals:

Remove jewelry when doing household chores, gardening, exercising, swimming, or applying lotions and perfumes.

Avoid wearing your jewelry when handling strong chemicals like bleach or ammonia.

Store your jewelry separately in a soft-lined box or pouch to prevent scratches from contact with other pieces.

By following these simple steps, you can dramatically extend the life of your jewelry’s brilliance and beauty.

IV. Moissanite’s Durability Compared to Other Stones

Moissanite isn’t just beautiful — it’s one of the toughest gemstones available, making it an outstanding choice for everyday wear.

On the Mohs scale of mineral hardness, diamonds score a perfect 10. making them the hardest material found in nature. Moissanite closely follows at 9.25. which means it’s harder than nearly every other gemstone commonly used in jewelry, including sapphires (9) and significantly harder than cubic zirconia (CZ), which rates at about 8–8.5.

Because of its impressive hardness, Moissanite resists scratches, chips, and abrasions far better than many alternative stones. Additionally, it maintains its color and clarity over time without the yellowing, clouding, or surface dulling often seen in less durable materials like cubic zirconia.

Unlike white sapphires, which can appear cloudy or scratched after extended use, Moissanite remains optically vibrant and retains its fiery brilliance for decades. This resilience, combined with its ethical sourcing and affordability compared to natural diamonds, makes Moissanite a standout choice for both engagement rings and fine jewelry collections.

When you choose Moissanite, you’re choosing a gem that’s designed to last — sparkling through life’s every chapter right alongside you.

Conclusion

The fear that Moissanite might become cloudy over time is a myth — one that can easily be put to rest with a little understanding and care. Thanks to its durable chemical structure, Moissanite does not lose its internal brilliance or develop cloudiness as it ages. Any dullness you might observe is almost always temporary, caused by surface residues from daily life, and can be effortlessly restored with simple cleaning practices.

Moissanite’s incredible combination of beauty, durability, and ethical origins makes it a gemstone you can confidently wear and cherish for years to come. With just a little regular care and thoughtful wear, your Moissanite jewelry will continue to dazzle with the same breathtaking fire and brilliance that first captured your heart.

So go ahead — wear your Moissanite every day, celebrate your milestones, and create memories without worry. Its sparkle is here to stay.
