Moissanite

Moissanite () is a kind of silicon carbide, a mineral. It can be found in nature, and it has some polymorphs. 

It has the chemical formula SiC. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893.

Origin of the name of the mineral: The mineral form of silicon carbide, was named (after Henri Moissan, or) in honor of Moissan.

 Uses (or applications) 

Moissanite came into the jewelry market as a diamond alternative in 1998 after Charles & Colvard (formerly known as C3 Inc.) got patents to create and market some kinds of gemstones; Those stones were (made in a laboratory, or they were) lab-grown silicon carbide gemstones. The company was the first to do that. By 2018, all patents on the original process world-wide, had (ended or) expired. Several companies have used [their own trademark, or] a trademark. Some trademarks that have been used are, Forever One, Forever Brilliant, and Forever Classic. Other manufacturers (sell or) market silicon carbide gemstones under trademarked names such as Amora.

Use as a fake diamond: Sometimes the mineral gets used as (a fake or) counterfeit diamond. Testing equipment that (uses or) is based on thermal conductivity can give test results similar to diamond.

Diamond testers (a kind of machine), sometimes make mistakes when used on moissanite.https://www.brilliantearth.com/gemstones/buying-guide/moissanite/does-moissanite-pass-diamond-tester/. Retrieved 2025-09-26
