Dr. Ferdinand Frédéric Henri Moissan
The Meteorite Impact
Around 50,000 years ago, an iron-nickel meteorite slammed into what is now northern Arizona, carving out the massive Canyon Diablo Meteor Crater (also known as Barringer Crater). Deep within the extraterrestrial rock samples carried by that meteorite were microscopic particles of a mineral never before seen on Earth.
Dr. Henri Moissan’s Discovery (1893)
In 1893, the renowned French chemist Dr. Ferdinand Frédéric Henri Moissan was examining rock specimens collected from the Canyon Diablo crater.
The Initial Mistake: When Dr. Moissan first spotted tiny, brilliantly sparkling crystals embedded in the rock, he initially believed he had uncovered microscopic diamonds.
The Revelation: After years of chemical analysis, Dr. Moissan realized in 1904 that these crystals were not carbon (diamond), but rather naturally occurring silicon carbide (SiCSiC).
The Naming: In 1905, the mineral was officially named Moissanite in honor of Dr. Moissan's pioneering work.
(In 1906, Dr. Henri Moissan won the Nobel Prize in Chemistry, primarily for his work in isolating fluorine and developing the electric arc furnace.)
Rarity & The Lab Breakthrough
Naturally occurring moissanite is astronomically rare. Because natural supply is restricted to rare meteorites and tiny traces in the Earth's upper mantle, natural moissanite crystals are too small and scarce to cut into jewelry.
Lab Synthesis: In the late 1980s and 1990s, scientists developed advanced thermal processes to grow large, gem-quality single crystals of silicon carbide in laboratory environments.
Jewelry Debut: By 1998, lab-grown moissanite officially entered the fine jewelry market as a brilliant, durable, and conflict-free alternative to diamonds.
Why Moissanite Stands Out Today
Fire & Brilliance: Moissanite has a higher refractive index than diamond, giving it an extraordinary "rainbow" sparkle.
Extreme Hardness: Ranking at 9.25 on the Mohs hardness scale, it is second only to diamond (10) and harder than sapphire or ruby (9).
Cosmic Origin: Every piece of moissanite jewelry pays homage to that original stardust found at Meteor Crater.
