Will Moissanite Last Forever?

Moissanite is known for its dazzling sparkle, ethical sourcing, and affordability—but many buyers still wonder:
Will moissanite last a lifetime, or is it just a temporary substitute for a diamond?

At Diamond Lab, we work with both moissanite and lab-grown diamonds, and we can confidently say that moissanite is built to last. But understanding what “forever” really means requires a closer look at the stone’s physical properties, long-term performance, and how it compares to traditional gemstones like diamonds.

Let’s break it down.

What Makes a Stone “Forever”?

For a gemstone to truly last a lifetime, it must:

• Be hard enough to resist scratches and abrasions

• Be tough enough to survive daily wear and impacts

• Maintain its optical brilliance over decades

• Be resilient to heat, chemicals, and environmental stress

So how does moissanite hold up?

Moissanite’s Hardness: 9.25 on the Mohs Scale

Moissanite scores 9.25 on the Mohs hardness scale, making it the second hardest gemstone used in jewellery, after diamond (which scores a 10).

This high hardness means moissanite:

• Is very difficult to scratch

• Won’t cloud, chip, or dull easily

• Can stand up to daily wear like an engagement ring or wedding band

💡 For comparison:

• Sapphire = 9

• Emerald = 7.5–8

• Quartz (often found in dust) = 7

So moissanite is harder than most substances it will encounter in daily life.

Is Moissanite Durable for Everyday Wear?

Yes—moissanite is also tough, which refers to its ability to resist cracking or breaking under pressure.

It’s:

• Heat-resistant

• Chemically stable

• Less brittle than many other gemstones

• Unaffected by moisture, light, or temperature fluctuations

That said, like any fine jewellery, a moissanite ring should still be treated with care—removed during heavy labour, gym workouts, or harsh chemical exposure.

Does Moissanite Lose Its Sparkle Over Time?

One of the most common myths about moissanite is that it gets “cloudy” over time. This is false for high-quality stones.

✅ Moissanite retains its brilliance and fire for decades, provided it’s kept clean.
☑️ No yellowing, hazing, or fading will occur under normal conditions.

To maintain its sparkle:

• Clean regularly with warm water and a soft brush

• Avoid harsh chemicals like bleach or chlorine

• Use a jewellery cloth or ultrasonic cleaner occasionally

Moissanite vs Diamond: Which Lasts Longer?

While diamonds remain the hardest natural material on Earth, moissanite is close enough in performance that most people will never see a difference in lifespan.

Diamonds may retain a sharper polish over 50+ years, but moissanite is just as suitable for heirloom jewellery—especially when properly set and maintained.

So… Will It Last Forever?

Yes—moissanite is absolutely a lifelong stone.

It’s not just a “starter stone” or a short-term compromise. Many couples today are choosing moissanite as their forever choice, not a placeholder, because:

• It’s beautifully brilliant

• It’s ethically created

• It’s exceptionally strong

• And it offers excellent value for a large, high-clarity stone

Moissanite Ring Tips for Longevity

To ensure your moissanite ring lasts forever:

• Choose a protective setting (e.g. bezel or halo for active lifestyles)

• Clean your stone every 1–2 weeks at home

• Have it professionally cleaned and checked once a year

• Store in a soft pouch or box when not worn

💡 Regular care helps preserve not just the stone, but also the metal and setting integrity.
