Why YCL Works with Moissanite

Moissanite is a rare naturally occurring mineral, was named after a French doctor who discovered the silicon carbide matter at a meteorite strike site in Arizona in 1893. After his discovering, a thermal growing process that creates these silicon carbide crystals was developed and this is now how moissanite gemstones are formed.


Durability: Gemstones are measured on the Mohs Scale of Hardness, which assesses a stones ability to withstand surface scratching.

Moissanite scores a 9.25 on the Mohs scale. This makes it one of the hardest substances on earth and suitable for ceremonial rings that are worn daily.

Brilliance: Refers to the stones ability to reflect white light.

Moissanite reflects light beautifully and often refracts light in a way that creates a 'rainbow effect’. Moissanite has a refractive index from 2.65 – 2.69, which is higher than a diamond.


The cost of moissanite stones do vary depending on size, cut & carat, however typically cost far less than diamonds.


Moissanite stones are not mined meaning there is no risk of unsustainable gem mining, lack of rehabilitation to the environment, exploitation of human labor, or indirectly supporting conflict.
