The story of SiC, Silicon carbide or Moissanite as we know it today.

SiC Silicon carbide also know as carborundum, is a semiconductor containing silicon and carbon. Today Known as Moissanite.

1893

Discovery of Natural Moissanite

In 1893, Moissan began studying fragments of a meteorite found in Meteor Crater near Diablo Canyon in Arizona. In these fragments he discovered minute quantities of a new mineral and, after extensive research, Moissan concluded in 1904 that this mineral was made of SiC silicon carbide. In 1905, this mineral was named moissanite, in his honour.
1906, Moissan received the Nobel Prize in Chemistry.

1893

Production of SiC / Moissanite

Synthetic SiC Moissanite powder has been produced since 1893 and played an important industrial role as an abrasive. The growth of single crystals of silicon carbide has been studied for many years for two possible end uses: as a semiconductor material, and as a diamond substitute in jewellery. At the time, no method had been found to control the colour and the growth process to make synthetic moissanite suitable for the jewellery industry.

1996

Moissanite Entered the Market

The controlled growth of synthetic moissanite has been achieved. Synthetic moissanite appeared in the jewellery & gemmological market in 1996, limited by the distribution from C3 Inc. C3 Inc, named this synthetic stone: “Lab-Created Moissanite Gemstones TM”. However, in accordance with CIBJO rules (International Con­federation of Jewellery, Silverware, Diamonds, Pearls and Stones), it should only be called “Synthetic Moissanite” (CIBJO, 1999-Gem­stone Book Art. 8).
However due to the scarcity of Natural Moissanite, and the fact that no common man will ever come across a Natural Moissanite, the name, as we know it today “Moissanite” was adopted by the consumer market referring to synthitic Moissanite.

2015

Expiration of Patent

The use of Moissanite in jewellery was controlled by the patents held by 3C Inc. In August 2015 the patent expired in the United States, followed in 2016, in most other countries, and 2018 in Mexico. This allowed for a competing market to create a more superior Moissanite to be distributed. The Manufacturing of Moissanite is now open world wide.
