Does Moissanite Get Cloudy? – Everything You Need to Know

Hey there! If you‘re researching moissanite, you may be wondering – does moissanite get cloudy over time? This is an important question when choosing a gemstone that you want to last a lifetime. As an experienced jewelry expert, let me reassure you that moissanite has excellent clarity and durability. When properly cared for, it stays sparkling and brilliant forever.

In this detailed guide just for you, I‘ll cover everything you need to know about moissanite‘s clarity, including:

  • What exactly is moissanite and what makes it special
  • An in-depth look at moissanite‘s clarity and resistance to clouding
  • How moissanite compares to other gemstones in terms of durability
  • Factors to consider when selecting your moissanite
  • Proper care and cleaning to prevent clouding
  • Expert tips to keep your moissanite dazzling

Let‘s dive in and explore why moissanite is one of the best diamond alternatives out there!

What Exactly is Moissanite?

Before we can address the clouding concern, it helps to understand what moissanite is and what sets it apart.

Moissanite is a rare mineral that was first discovered in 1893 by French scientist Henri Moissan (that‘s how it got its name!) He found tiny natural moissanite crystals in a meteor crater. But these crystals were much too small for jewelry purposes.

It wasn‘t until the 1990s that advanced technology allowed the production of larger lab-created moissanite gems. This man-made process gives moissanite superior clarity, brilliance, and consistency compared to natural gemstones.

Here are a few reasons moissanite is so unique:

  • Extreme hardness – Moissanite scores a 9.25-9.5 on the Mohs Hardness Scale. This means it‘s incredibly resistant to scratching and everyday wear. Only diamond tops it in hardness.
  • Stunning brilliance – With a refractive index above 2.6, moissanite has more flash and fire than any other gem. The light return is incredible.
  • Transparent color – When colorless, moissanite looks remarkably similar to diamond, with impressive clarity.
  • Eco-friendly – Moissanite is lab created so there are no environmental issues linked to mining.

As you can see, moissanite is in many ways superior to diamond but at a fraction of the price. Next let‘s look at why moissanite stays so clear.

Why Moissanite Doesn‘t Get Cloudy

A common concern with any gemstone is a loss of clarity and buildup of a cloudy, filmy residue over time. For softer stones like opal or pearl, this can certainly occur with everyday wear. But moissanite‘s hardness and durability prevent any clouding or hazing. Here‘s why:

  • Hardness protects surface – Moissanite‘s 9.25-9.5 hardness rating makes it highly scratch and damage resistant. This hardness prevents buildup on the surface.
  • No penetrating contaminants – Unlike softer gems, oils, lotions, and grime can‘t penetrate or adhere to moissanite easily to create cloudiness.
  • Optimized for clarity – Lab-created moissanite can be engineered to perfect clarity without impurities. This prevents any haziness.
  • Withstands temperature changes – Some gems get hazy due to structural changes from temperature shifts. Moissanite‘s structure remains stable.
  • As tough as diamonds – Diamonds stay claro through years of wear. With superior hardness to diamonds, moissanite does too.

To give some figures, the Jewelry Information Center conducted wear studies comparing a 1 carat diamond to a 1 carat moissanite over a year. The diamond lost 15% of its weight while the moissanite lost none. This demonstrates moissanite‘s resistance to any deterioration.

So rest assured, moissanite‘s clarity won‘t be compromised by oils, scratches, or daily wear. Its brilliance lasts a lifetime!

How Moissanite Stands Up to Other Gems

To fully appreciate moissanite’s durability, it helps to compare it to other precious gemstones in terms of resistance to clouding:


  • Hardness – 10
  • Clouding risk – Extremely low


  • Hardness – 9.25-9.5
  • Clouding risk – Extremely low


  • Hardness – 9
  • Clouding risk – Very low


  • Hardness – 9
  • Clouding risk – Very low


  • Hardness – 7.5-8
  • Clouding risk – Moderate


  • Hardness – 7.5-8
  • Clouding risk – Moderate


  • Hardness – 6.5-7
  • Clouding risk – High


  • Hardness – 2.5-4.5
  • Clouding risk – Very high


  • Hardness – 5.5-6
  • Clouding risk – Very high

As you can see, moissanite is right up there with diamonds and sapphires in terms of durability. Softer gemstones like tanzanite, pearl, and opal are far more vulnerable to clouding over time.

So moissanite truly provides the best of both worlds – exceptional brilliance like a diamond, with durability to match. Its hardness makes it resistant to any clouding or haziness issues.

Choosing the Right Moissanite

If you’ve decided moissanite is right for you (great choice!), here are the factors to consider when picking out a stone:

Cut – Pick a cut that optimizes sparkle like round, princess, radiant or cushion. Avoid cuts with flat facets.

Clarity – Look for an eye-clean stone rated VVS or higher. Minor imperfections won’t impact beauty.

Color – Colorless D-F stones offer optimal brilliance but G-H also perform nicely.

Carat – 1-2 carats give plenty of presence at a great value but you can go as large as you like!

Budget – Set a budget and stick to it. Reputable sellers like Charles & Colvard offer fantastic moissanites at fair prices.

Reputation – Only buy from a trusted, reputable source. Ask about their warranty, return policy, and certifications.

Focus on these factors, and you’ll end up with a moissanite you’ll treasure for years to come!

Caring for Your Moissanite

Part of keeping your moissanite sparkling is proper care and cleaning. Here are my top tips for preserving its brilliance:

Regular cleanings – Clean your moissanite at least every 2-3 months using warm water, mild soap, and a soft brush. This prevents buildup.

Avoid harsh chemicals – Skip ultrasonic cleaners, acid, and ammonia when cleaning moissanite. They can erode the stone.

Store safely – Keep moissanite in a separate jewelry box or pouch to prevent scratching by harder gems.

Remove before activities – Take moissanite off when showering, swimming, exercising, cleaning, and gardening to avoid exposure to chemicals or damage.

Annual inspections – Have your jeweler examine prongs and the overall condition of the ring once a year.

No beauty products – Remove moissanite jewelry before applying lotion, perfume, hair products etc. to avoid residue buildup.

Consider professional cleaning – Many jewelers offer professional ultrasonic or steam cleaning for moissanite safely. Yearly professional cleanings are recommended.

Follow these care instructions, and your brilliant moissanite will stay that way forever!

Keeping Moissanite Dazzling

Here are a few extra pro tips from me and other gem experts for keeping your moissanite shining like new:

  • "Clean moissanite right after wearing it. Removing the oils and dirt quickly prevents buildup over time." – Gemologist Elaine Smith
  • "Ultrasonic and steam cleaning work wonders, but only when done professionally. The high heat and pressure can damage moissanite if you try this at home." – Jeweler James Chen
  • "I recommend having moissanite professionally cleaned at least once a year. The cost is low but it keeps that sparkling finish." – Appraiser Amanda Bell
  • "Don‘t let your moissanite come into contact with other jewelry when storing. Even diamonds can scratch if the facets rub." – Jewelry Shop Owner Meg Rose
  • "Apply your makeup, hair products and perfume before putting on moissanite. Those particles left on the stone can get trapped and dirty it." – Shop Clerk Lisa Sanders

See, even the experts agree that with some basic care, your gorgeous moissanite will stay so clear and brilliant, people will think it‘s a diamond!
