What is a Moissanite?

When it comes to choosing the perfect gemstone for an engagement ring or other jewellery, many individuals are exploring alternatives to traditional diamonds.

Moissanite is a gemstone composed of silicon carbide (SiC). It was first discovered in 1893 by Henri Moissan, a Nobel Prize-winning chemist, in a meteorite crater in Arizona. Initially, it was mistaken for diamonds, but upon further analysis, it was identified as a new and unique mineral.

While moissanite was initially discovered in a meteorite, the moissanite used in jewellery today is typically lab-grown.

Moissanite's composition sets it apart from diamonds. Comprising silicon and carbon, moissanite has a crystal structure that differs from that of diamonds. 

One of the standout features of moissanite is its remarkable hardness. While diamonds top the Mohs scale with a perfect 10, moissanite's hardness at 9.25 makes it highly resistant to scratching, chipping, and breaking. This durability makes moissanite an excellent choice for everyday wear.

Moissanite dazzles with its brilliance and sparkle, thanks to its high refractive index. The gemstone disperses light exceptionally well, creating colorful flashes known as "fire." Many individuals appreciate the fiery and vibrant display of light that moissanite offers, giving it a distinct character.

Moissanite is available in various colours, Avamore Moissanite only use the best grades D-F for white moissanite.
