Moissanite is an almost colourless gemstone that is made from silicon carbine. It was first discovered in its natural state by Henri Moissan, a French scientist, in 1893.
Natural Moissanite is extremely rare which makes it impractical for use in jewellery. So it is manufactured in a laboratory using the same material found in natural Moissanite - Silicon Carbide. So it is essentially, the same thing.
Gemstones are measured on a scale referred to as the "Mohs" scale of hardness. A diamond is the highest gemstone on this scale which rates from 0 - 10. Diamonds sit at 10 on the Mohs scale. Moissanite has a Mohs hardness of 9.-9.5. Tungsten carbide sits at 9 and Titanium at 6.
The refractive index is a measure of the speed at which light moves through material and gives of its brilliance or sparkle. The refractive index of moissanite and diamond is very similar, but Moissanite sits at 2.65 and diamonds at 2.42. This means that a moissanite will appear to have MORE sparkle than a diamond of the same size.
