Will Moissanite Fade? 2025
When I first began reporting on gemstone innovations and the rise of lab-created jewels, one question popped up repeatedly from readers and clients alike: “Will moissanite fade over time?” As a jewelry specialist who has handled, tested, and worn moissanite pieces daily, I can confidently tell you—this sparkling stone is built to last.
In the world of fine jewelry, concerns about fading, clouding, or discoloration are natural. Diamonds, sapphires, and emeralds have centuries of reputation to lean on, but moissanite is a relative newcomer in the consumer jewelry market. While it was originally discovered in a meteor crater in 1893 by Henri Moissan, today’s moissanite is carefully grown in laboratories, engineered for brilliance, and crafted to endure everyday wear.
Unlike many gemstones or simulants (such as cubic zirconia), moissanite does not fade, lose color, or become dull with time. Its structure and durability rival—and in some ways even surpass—traditional diamonds. That’s why jewelers worldwide are embracing moissanite engagement rings, earrings, and necklaces as a sustainable and affordable alternative without compromising beauty.
In this article, I’ll break down exactly why moissanite never fades, how it compares to diamonds and other stones, and what you can do to keep your jewelry looking radiant for decades. By the end, you’ll understand not only the science behind moissanite but also why it has become a smart choice for those who want brilliance that lasts a lifetime.

What Is Moissanite?
Moissanite is a lab-created gemstone made of silicon carbide. Though it looks remarkably similar to a diamond, it is a unique stone with its own set of exceptional qualities. What makes it stand out is its incredible fire and brilliance—the rainbow-like flashes of light that moissanite produces are actually higher than those of a diamond.
Because natural moissanite is exceedingly rare, virtually all moissanite on the market today is grown in controlled laboratory environments. This ensures consistent quality, sustainable production, and ethical sourcing—three pillars that modern buyers care deeply about.
Will Moissanite Lose Its Sparkle or Fade?
The short answer: No, moissanite does not fade.
Moissanite is inherently color-stable. Unlike other stones, its structure is resistant to environmental changes such as heat, light exposure, and household chemicals. In fact:
-
No fading with time: Unlike cubic zirconia, which can yellow or cloud, moissanite maintains its colorless or near-colorless appearance for life.
-
No dulling of brilliance: Its refractive index (2.65–2.69) is higher than diamond, meaning it sparkles with unmatched intensity.
-
No chemical breakdown: Everyday exposure to cleaning products, lotions, or sunlight won’t damage its clarity or brightness.
The only thing that can make moissanite appear dull is surface buildup from oils, lotions, or dirt. Fortunately, that’s easily fixed with regular cleaning.

Why Doesn’t Moissanite Fade? The Science Behind It
To understand why moissanite never fades, it helps to look at its science:
-
Hardness: Moissanite ranks 9.25 on the Mohs scale of hardness (diamond is 10). This means it is incredibly scratch-resistant and suitable for everyday wear.
-
Stability: It is highly stable under ultraviolet light, heat, and exposure to most chemicals. Unlike some gemstones, it doesn’t react or change color with age.
-
Durability: Moissanite’s toughness—its ability to resist breaking or chipping—makes it a long-lasting stone for rings and heirloom pieces.
Simply put, the material itself is engineered to endure, making it virtually impossible for the stone to fade or discolor over time.
Common Myths About Moissanite Fading
Myth 1: Moissanite turns yellow over time
This misconception often comes from confusion with cubic zirconia. CZ tends to discolor and lose brilliance with age, but moissanite remains color-stable forever.
Myth 2: Moissanite loses its sparkle after years of wear
Any gemstone can look dull if it’s dirty. But with a quick cleaning—either at home with warm soapy water or professionally—moissanite returns to its original brilliance.
Myth 3: Heat from jewelry repair will damage moissanite
In reality, moissanite can withstand high temperatures and is safe during jewelry repairs. A skilled jeweler will have no issues working with it.

Moissanite vs. Diamond: Which Lasts Longer?
Both moissanite and diamonds are prized for durability, but they differ slightly in characteristics:
-
Diamond: The hardest known natural substance, ranking 10 on the Mohs scale. Resistant to scratches and fading.
-
Moissanite: Nearly as hard, ranking 9.25, with higher brilliance and fire. Equally resistant to fading and discoloration.
In terms of longevity, both are lifetime stones. The deciding factor often comes down to price, sustainability, and aesthetic preference.
How to Keep Moissanite Sparkling
Even though moissanite itself doesn’t fade, proper care ensures it looks its best. Here are a few professional tips:
-
Regular cleaning: Use warm water, mild soap, and a soft toothbrush to remove buildup.
-
Ultrasonic cleaners: Moissanite is safe for ultrasonic and steam cleaning, unlike softer gemstones.
-
Avoid harsh abrasives: While moissanite is tough, avoid scrubbing with rough materials that might scratch the metal setting.
-
Professional check-ups: Have your jeweler inspect the setting annually to ensure the stone is secure.
