Is Moissanite from Space? 2025
As a jewelry reporter and gemstone enthusiast, I’ve spent years unraveling the mysteries behind the sparkle that captivates us. One of the most intriguing questions I hear often is: “Is moissanite from space?” The short answer is yes—natural moissanite was first discovered in a meteor crater over a century ago. But the story doesn’t end there. While this cosmic origin fuels its mystique, the moissanite you’ll find in fine jewelry today is not harvested from stardust but rather grown in advanced laboratories.
In this article, I’ll break down the fascinating history, science, and symbolism behind moissanite’s celestial reputation. You’ll learn how Henri Moissan’s 1893 discovery reshaped gemstone science, why natural moissanite is so rare it’s practically unobtainable, and how modern technology allows us to recreate this space-born crystal with stunning brilliance.
Whether you’re considering moissanite for an engagement ring or simply curious about its cosmic backstory, my goal is to give you an authoritative, transparent, and SEO-rich deep dive into what makes this gemstone so unique. Let’s explore whether moissanite truly is a “gem from the stars”, and how its space-age beginnings make it one of the most exciting and ethical alternatives to diamonds available today.

The Meteoric Discovery of Moissanite
In 1893, Nobel Prize-winning chemist Henri Moissan discovered tiny, sparkling crystals in a meteor crater in Canyon Diablo, Arizona. Initially mistaken for diamonds, these crystals were later identified as silicon carbide (SiC), a compound never before seen in nature. Because of its extraterrestrial discovery, the mineral was named moissanite in his honor.
This cosmic origin gave moissanite a reputation as a gem from the stars, a distinction no other popular gemstone can claim. However, natural moissanite is so rare on Earth that it cannot meet commercial demand, making lab-created moissanite the standard in today’s jewelry industry.
Is Moissanite Really from Space?
The answer is both yes and no.
-
Yes: The first moissanite crystals ever found originated from a meteorite, meaning their true birthplace was likely outer space.
-
No: The moissanite used in jewelry today is lab-grown, created under controlled conditions to match and even surpass the optical brilliance of natural samples.
This dual truth gives moissanite an almost mythical allure—it carries cosmic origins yet is accessible, sustainable, and ethical thanks to modern technology.

Lab-Created Moissanite: The Modern Star Stone
Because natural moissanite is virtually impossible to source in usable quantities, scientists developed methods to grow silicon carbide crystals in laboratories. This innovation made moissanite an affordable, eco-friendly gemstone alternative.
-
Brilliance & Fire: Moissanite has a higher refractive index (2.65–2.69) than diamond, meaning it produces more sparkle and rainbow flashes.
-
Durability: With a Mohs hardness rating of 9.25, moissanite is second only to diamond, making it ideal for daily wear.
-
Affordability: Lab-grown moissanite costs a fraction of natural diamonds, making luxury more accessible without ethical compromises.

-
Its discovery in a meteor crater—a literal connection to outer space.
-
Its futuristic production methods—grown with high-tech processes resembling science fiction.

|---|---|---|
| Origin | Meteorite discovery & lab-grown | Earth’s mantle, mined |
| Brilliance (Fire) | More colorful sparkle | Classic white brilliance |
| Durability | 9.25 Mohs hardness | 10 Mohs hardness |
| Price | Affordable | Expensive |
| Ethical & Eco Impact | Lab-created, sustainable | Often mined, environmental toll |
This comparison reveals why moissanite engagement rings are rising in popularity—they deliver cosmic sparkle with ethical clarity.

The Science of Stardust: Silicon Carbide in Space
Beyond jewelry, silicon carbide (SiC) has been found in meteorites, stardust, and even around dying stars. In astrophysics, these tiny crystals are studied to understand how elements form in space. This scientific reality makes moissanite not just a marketing story, but a gemstone with genuine cosmic significance.
