How Are Moissanite’s Made?

Natural Moissanite is originally a gemstone that came from a meteor originally found in 1893. Since then using high tech lab equipment we have been able to reproduce the chemical structure of this beautiful gemstone. Its made using silicon and carbon with both heat and pressure in a chamber to produce a man made form of silicon carbide which is then faceted and polished to make the gemstone we see and know today as Moissanite.


How Strong Are Moissanites?

This man-made stone is simply stunning, being 9.5 on the hardness scale, its hardness lies between sapphire and diamond. A great option for daily wearing, with its fantastic harness and optical properties, its almost impossible to tell the difference with the naked eye between a moissanite and a lab grown diamond.


Moissanite is created with silicon and carbon through both pressure and heat to begin the moissanite manufacturing process.
The production and manufacturing process costs are no where near the costs to product a lab grown diamond and even more significantly less with a mined diamond.
