THE STORY OF MOISSANITE

A fragment from the stars. A discovery that changed jewelry.

The story of moissanite begins not in a workshop, but in the study of a meteorite—and with the curiosity of French chemist Henri Moissan.

A rare crystal, first found in the study of a meteorite

In 1893, Moissan examined fragments associated with the Canyon Diablo meteorite in Arizona. Inside them he observed tiny, brilliant crystals. Their resemblance to diamonds captured his attention; later mineralogical work established that this rare natural material was silicon carbide (SiC), distinct from diamond.

The mineral was later named moissanite in his honor. Natural crystals are so rare and small that they are not the source of the gemstones used in modern jewelry.

Moissanite is silicon carbide; diamond is crystallized carbon. Their beauty may share the light, but their stories and composition are different.

FROM RARE MINERAL TO GEMSTONE

A discovery carried forward

  1. 1893

    Moissan studies meteorite fragments from Canyon Diablo.

  2. 1904

    He publishes his experiments on diamond synthesis and silicon carbide crystals.

  3. 1990s

    Advances in crystal growth make larger, gem-quality silicon carbide possible.

  4. 1998

    A US patent documents silicon carbide gemstones; moissanite enters the jewelry market.

At Argentum, we honor that legacy of curiosity with contemporary jewelry in which every stone has a story—and every design can become personal.
