The History of Moissanite: From Meteorite to Fine Jewelry

September 6, 2026

Every moissanite ring contains a stone with an origin story unlike any other gemstone on Earth. Understanding where moissanite comes from — and how it became the world’s most optically brilliant fine jewelry stone — changes how you see it the moment it catches the light.

1893: The Meteorite Discovery

In 1893, French chemist Henri Moissan was examining rock samples from the Canyon Diablo meteorite crater in Arizona — the impact site of a massive iron-nickel meteorite that struck the Arizona desert approximately 50,000 years ago. In those samples, Moissan identified tiny crystals of a compound never before seen in nature: silicon carbide (SiC). The mineral was later named moissanite in his honor. Moissan received the Nobel Prize in Chemistry in 1906.

Natural moissanite forms under extreme conditions — inside large meteorites and in the mantles of certain stars. On Earth’s surface, these conditions simply do not occur. All the natural moissanite ever found on Earth would not fill a teacup. Every moissanite engagement ring available today is lab-created — which, as it turns out, is a significant advantage.

1987–1998: The Laboratory Breakthrough

In 1987, Cree Research (now Cree Inc.) developed Physical Vapor Transport (PVT) — a process for growing large, high-quality silicon carbide crystals for use in semiconductors. Charles & Colvard licensed this technology to create jewelry-grade moissanite. In 1998, the first moissanite engagement rings reached the fine jewelry market, immediately recognized for their extraordinary brilliance and fire.

The Optical Discovery: More Brilliant Than Diamond

When gemologists formally measured moissanite’s optical properties, the results were remarkable. Moissanite’s refractive index is 2.65–2.69 — diamond’s is 2.42. More significantly, moissanite’s dispersion (the property that creates fire — rainbow spectral color) is 0.104 versus diamond’s 0.044. Moissanite has 2.4 times more fire than diamond. Under direct light, a moissanite solitaire engagement ring produces dramatically more spectral color than an equivalent diamond ring.

2000s–2010s: The DEF Color Revolution

Early moissanite had a slight yellowish or greenish tint visible under certain lighting — a limitation of early PVT growth. As the technology matured through the 2000s and 2010s, manufacturers achieved consistently colorless production. By the mid-2010s, DEF-color moissanite — fully colorless, equivalent to the highest diamond color grades — was commercially available.

Today: The Fine Jewelry Standard

Today, moissanite fine jewelry is graded against the same standards as diamond: DEF color (colorless), VVS1 clarity (near-flawless), Excellent cut, independently certified by GRA. The 9.25 Mohs hardness that made silicon carbide valuable for industrial cutting tools makes moissanite equally durable for a lifetime of daily wear. A DEF/VVS1 moissanite engagement ring purchased today will look identical in 50 years.

Beyond rings, moissanite earrings, moissanite necklaces, and moissanite bracelets bring the same cosmic-origin brilliance to every piece of fine jewelry.

The Meteorite Connection: What It Means for Your Ring

The silicon carbide in every moissanite stone is chemically identical to what Henri Moissan found in that Arizona meteorite in 1893. Lab creation doesn’t change the compound — it changes the origin. Natural moissanite came from space. Lab moissanite comes from a controlled crystal growth process that replicates those extreme conditions precisely. Every stone carries the heritage of a cosmic material — one that arrived from space, was identified by a Nobel Prize winner, and spent a century as a scientific curiosity before becoming the world’s most optically brilliant fine jewelry gemstone.
