Where Does Moissanite Come From? The Space Gem Origin Story
March 19, 2026
Short answer: naturally occurring moissanite comes from space. It forms in the cores of dying stars, arrives on Earth inside meteorites, and is so rare that no one has ever cut a wearable gemstone from it. Every moissanite you can actually buy — including every stone we set — is grown in a laboratory from silicon and carbon, the same two elements those meteorite crystals are made of. The mineral is cosmic. The stone on your finger was made here on Earth.
Below: where moissanite is found in nature, whether it is mined anywhere, how the lab-grown version is actually made, and when it became a jewelry stone.
A Gem Born from the Stars
Imagine a gemstone that didn't begin its journey in a mine or a quarry. Imagine a stone that traveled millions of miles through the vastness of space, survived a catastrophic collision with Earth, and lay hidden for millennia before scientists finally understood what they'd found.
This is the story of moissanite.
Unlike diamonds, rubies, or emeralds - gemstones that form deep within the Earth under pressure and heat - moissanite's origin story reaches beyond our planet. It's a stone that came from the cosmos, discovered in a meteor crater, and it carries with it the romance and mystery of space itself.
The remarkable journey of moissanite spans centuries of scientific discovery, astronomical wonder, and eventually, a revolution in how we think about precious gemstones. And it all begins with a meteor, a crater in Arizona, and a brilliant scientist who would change the world of chemistry forever.
The Discovery: Arizona, 1893
It began with a meteorite. In 1893, a meteor crashed into the Arizona desert, creating the impact crater now known as Canyon Diablo. For centuries, the crater and its meteorite fragments lay undisturbed, waiting to tell their story to the world.
Then, a brilliant French chemist named Henri Moissan — who would later win the Nobel Prize in Chemistry — examined fragments of this meteorite. Among the iron and stone, he discovered something extraordinary: tiny, glimmering crystals that he initially mistook for diamond.
At first, Moissan believed he'd found diamonds from space. Diamond, after all, is the hardest natural substance known to science — what could be more plausible than a space-born diamond?
But as he studied these crystals more closely, something didn't add up. Their optical properties were different from diamond. Their refraction patterns were unusual. They sparkled differently, catching light in ways diamond couldn't quite replicate. Moissan realized he'd discovered something entirely new — a gemstone that had never been documented in scientific literature before.
The Scientist Behind the Discovery
Henri Moissan (1852–1907) was one of the most brilliant chemists of his era. He developed the electric arc furnace, made groundbreaking discoveries in fluorine chemistry, and earned the Nobel Prize in Chemistry in 1906. He was a researcher who pushed boundaries and asked questions that nobody else was asking.
When Moissan discovered this new crystal, he subjected it to rigorous analysis. Through meticulous scientific work, he identified it as silicon carbide (SiC) — a compound of silicon and carbon arranged in a crystalline structure. It was a compound that had never been found in nature before, at least not on Earth.
In honor of Moissan's discovery, the crystal was named moissanite — a tribute to the man who first recognized its significance.
The Mystery of Natural Moissanite
Here's where the story becomes truly fascinating: if moissanite naturally occurs in meteorites, where does it come from in space?
The answer lies in the heart of dying stars.
Scientists now understand that moissanite forms in the cores of giant stars — particularly red giant stars in the final stages of their lives. When these stars reach the end, their cores become sites of extreme temperature and pressure where silicon and carbon fuse into moissanite crystals. These crystals can then be ejected into space through stellar winds or supernova explosions.
When a meteorite carrying these space-born moissanite crystals crashes into Earth, it brings with it a fragment of stellar chemistry — actual material forged in the heart of a star, billions of years ago.
Why Is Natural Moissanite So Rare?
Given that moissanite forms in space and travels to Earth via meteorites, it's extraordinarily rare. The Canyon Diablo meteorite has yielded only tiny crystals — some barely visible to the naked eye. Other natural moissanite deposits exist in some rare rock types on Earth, but they're vanishingly uncommon.
Finding natural moissanite on Earth is like finding a needle in a cosmic haystack. Which is why, for over a century after Moissan's discovery, moissanite remained a scientific curiosity rather than a gemstone anyone could actually wear.
Where is moissanite found on Earth?
Outside meteorite fragments, terrestrial moissanite turns up in a small number of unusual geological settings. It has been identified as microscopic inclusions trapped inside other minerals, including within kimberlite and inside diamonds themselves, and in certain ultramafic and metamorphic rocks. In every one of those cases the crystals are microscopic and thinly scattered, which is why they end up in research papers rather than in jewelry.
The best known source is still the one Moissan worked with: fragments of the Canyon Diablo meteorite in Arizona.
Is moissanite mined?
No. There is no moissanite mine anywhere in the world, because there is no deposit concentrated enough to make mining possible. This is one of the clearest practical differences between the two stones people most often compare: a diamond has a mine behind it, and a moissanite has a laboratory. If a seller tells you their moissanite was mined, they are mistaken.
Then, in the 1990s, everything changed.
The Quest to Create Moissanite: From Lab to Jewelry
Henri Moissan discovers silicon carbide crystals in the Canyon Diablo meteorite in Arizona.
Scientists begin synthesizing silicon carbide in laboratories, but early versions are opaque and unsuitable for jewelry.
Charles & Colvard, a North Carolina-based company, develops the thermal growth process for lab-creating transparent, gem-quality moissanite suitable for jewelry.
Lab-created moissanite jewelry becomes commercially available to the public for the first time.
Moissanite becomes increasingly popular in fine jewelry, appreciated for its brilliance, durability, and ethical sourcing.
For nearly a century after Moissan's discovery, scientists knew moissanite was remarkable, but it remained locked in meteorites — inaccessible, unavailable, purely scientific.
Then, in the 1990s, researchers developed the capability to synthesize moissanite in controlled laboratory environments. More importantly, they figured out how to create moissanite crystals that were transparent, colorless, and facetable — suitable for jewelry.
The breakthrough came through a process called thermal growth. Scientists create the right conditions in a laboratory — precise temperatures, pressures, and chemical environments — and grow moissanite crystals slowly, layer by layer. The process is complex and requires significant expertise, but the results are remarkable: gem-quality moissanite crystals that rival (and in some ways exceed) natural moissanite in terms of clarity and brilliance.
How Lab-Created Moissanite Is Made (Simply Explained)
Imagine you're growing a crystal from scratch. You start with a tiny seed crystal of moissanite. You place it in a special chamber where silicon and carbon compounds can be introduced in a very controlled way. You apply heat — lots of it — and maintain specific pressure conditions. Slowly, over weeks or months, the moissanite crystal grows, one atomic layer at a time.
The result? A transparent, brilliant moissanite crystal that's indistinguishable from natural moissanite (which is itself so rare that almost nobody has ever seen a piece).
The beauty of lab-created moissanite is that you can control the growth process to ensure perfect clarity and ideal color. Natural moissanite? You take what the cosmos gives you — which is usually tiny fragments with impurities. Lab-created moissanite allows us to harness the extraordinary properties of this space gem and make it wearable, affordable, and accessible.
When did moissanite become popular in jewelry?
The commercial story starts in 1998, when the first gem-quality lab-grown moissanite reached the market. Through the 2000s it stayed a niche alternative that most buyers had never heard of. Its real growth came later, alongside the broader shift toward lab-grown stones, and it accelerated as buyers began comparing stones on brilliance, durability and price rather than on origin alone. What was a curiosity in 1998 is now a mainstream category.
Why Lab-Created Is Actually Better for Jewelry
Here's a counterintuitive truth: when it comes to jewelry, lab-created moissanite is actually superior to natural moissanite.
Consistency: Lab-created moissanite is grown under controlled conditions, ensuring consistent quality, clarity, and color. Every stone meets exacting standards.
VVS Clarity: Lab-created moissanite can achieve VVS (Very Very Slightly Included) clarity — essentially flawless — every single time. Natural moissanite crystals often contain impurities from their time in space.
Ethical Certainty: You know exactly where your moissanite came from — a laboratory, not from meteorites in contested territories or with unclear sourcing.
Availability: Lab-created moissanite can be produced in quantities sufficient for jewelry use. Natural moissanite is so rare that harvesting it from meteorites or geological deposits isn't practical.
Value: You get an objectively brilliant, durable, beautiful stone at a fraction of what natural moissanite fragments would cost (if they were even available for purchase).
Moissanite in Space: The Cosmic Connection Continues
The moissanite story doesn't end with laboratory creation. Scientists have continued to find evidence of moissanite throughout the cosmos.
Interstellar Dust: Moissanite crystals have been detected in interstellar dust — the material that floats between stars in our galaxy and beyond. Spectroscopic analysis reveals the signature of silicon carbide in various forms throughout space.
Pre-Solar Grains: Meteorites contain tiny grains of moissanite that predate our solar system — they formed in other star systems before being incorporated into meteorites that eventually reached Earth. Some of these grains are billions of years old.
Cosmic Significance: Finding moissanite in space tells us about stellar processes, the chemistry of dying stars, and the composition of the universe itself. It's not just a beautiful gemstone — it's a message from the cosmos.
Wearing a Piece of the Universe
When you wear a moissanite gemstone, you're wearing something genuinely extraordinary. You're wearing a stone whose molecular structure was first forged in the heart of a dying star, possibly billions of years ago. You're wearing cosmic chemistry. You're wearing a connection to the vast universe that surrounds us.
Even though your moissanite was created in a laboratory, it represents something cosmic. Its composition, its properties, its very essence — these are all connections to the stars.
There's a romance to this that goes beyond typical gemstones. A diamond is magnificent, yes — but it's terrestrial, formed under the earth. A moissanite? It's a space gem. It carries with it the story of dying stars, of meteorites streaking through the atmosphere, of a brilliant scientist in 1893 looking at a meteorite fragment and asking, "What is this?"

Frequently Asked Questions
Where does moissanite come from?
Naturally occurring moissanite comes from space. It forms in the cores of dying stars and reaches Earth inside meteorites, most famously the Canyon Diablo meteorite in Arizona. Because natural crystals are microscopic and extremely rare, all jewelry moissanite is grown in a laboratory from silicon and carbon.
Where is moissanite found in nature?
In meteorite fragments, and as microscopic inclusions inside other minerals such as kimberlite and diamond, plus a few ultramafic and metamorphic rock types. The crystals are always tiny and thinly scattered, which is why no natural source is commercially usable.
Is moissanite mined?
No. There is no moissanite mine anywhere in the world, because no deposit is concentrated enough to mine. Every moissanite sold as jewelry is lab-grown.
How is moissanite made?
Through a thermal growth process. A tiny seed crystal is placed in a chamber with silicon and carbon compounds at controlled temperature and pressure, and the crystal grows one atomic layer at a time over weeks or months. The rough crystal is then cut and polished like any other gemstone.
When did moissanite become popular?
Gem-quality lab-grown moissanite first reached the market in 1998. It remained niche through the 2000s and grew into a mainstream jewelry stone more recently, as buyers moved toward lab-grown stones generally.
Is all moissanite originally from space?
Moissanite as a mineral (silicon carbide) naturally forms in space — in the cores of dying stars and in meteorites. However, the moissanite used in jewelry today is lab-created in terrestrial laboratories. That said, lab-created moissanite is chemically and structurally identical to space-born moissanite. It's the same material, just created in a controlled environment rather than in the depths of space.
Can you buy natural moissanite from meteorites?
Natural moissanite from meteorites exists, but it's extraordinarily rare and typically available only as specimens to collectors or museums. The crystals are usually microscopic. It's not practical or commercially available as jewelry-grade stones. Lab-created moissanite is the only practical option for jewelry.
Why did it take so long to make jewelry-quality moissanite?
Creating transparent, gem-quality moissanite requires extremely specific conditions: precise temperatures, controlled chemical environments, and the right growth substrates. Early attempts at synthetic moissanite produced opaque or heavily colored stones unsuitable for jewelry. It wasn't until the 1990s that researchers figured out the thermal growth process that could produce clear, colorless, gem-quality crystals. It was a major breakthrough.
Is moissanite harder than diamond?
No. Diamond scores 10 on the Mohs hardness scale (the highest). Moissanite scores 9.25 — exceptional and second only to diamond. For practical jewelry purposes, this difference is negligible. Both are far harder than any other natural gemstone, and both are durable enough for everyday wear and to last a lifetime.
How brilliant is moissanite compared to diamond?
Moissanite has a higher refractive index than diamond, meaning it reflects more light and appears more brilliant. Some people love this intense sparkle; others prefer diamond's more subtle shimmer. It's entirely a matter of personal preference. Both are beautiful — just in different ways.
The Legacy of Henri Moissan
Henri Moissan passed away in 1907, just over a decade after discovering moissanite in the Canyon Diablo meteorite. He never knew that his discovery would one day become one of the most sought-after gemstones for fine jewelry. He didn't live to see labs create moissanite intentionally, or to see it set into rings and pendants worn by people around the world.
But his legacy endures. Every moissanite gemstone — whether we call it "the space gem," "the lab-created wonder," or simply a beautiful stone — carries his name. And it carries the story of a meteorite, a crater in Arizona, and a scientist who looked at something extraordinary and asked the right questions.
