In short<\/strong> Moissanite and diamond are two different stones. Moissanite (silicon carbide) throws more colorful flashes, is slightly less hard (9.25 on the Mohs scale, versus 10) and costs much less. Diamond, whether natural or lab-grown, is pure carbon: it is the hardest gemstone, with a whiter sparkle. When worn, from a short distance, they are hard to tell apart with the naked eye. Here are the real differences, backed by figures, so you can choose with confidence.<\/p>\n<\/div>\n

What is moissanite? A gemstone in its own right<\/h2>\n

Moissanite<\/strong> is named after the French chemist Henri Moissan, who identified it in 1893 in fragments of the Canyon Diablo meteorite in Arizona. Natural moissanite is so rare that it could never be used for jewelry: the moissanite used in fine jewelry is therefore created in a laboratory<\/strong>, and has been available since the late 1990s. It has its own composition (silicon carbide), its own crystal structure and its own optical properties: it is a gemstone in its own right, not a “fake diamond”. Nor does it have anything to do with cubic zirconia, which is much softer and scratches and clouds over time (moissanite on Wikipedia<\/a>).<\/p>\n

Diamond<\/strong> is crystallized carbon. It can be natural<\/strong> (formed deep in the Earth hundreds of millions or even billions of years ago) or lab-grown, also called synthetic<\/strong> (HPHT or CVD processes). A lab-grown diamond has the same composition, hardness and sparkle as a natural diamond: only laboratory equipment can tell them apart, and it must always be disclosed as lab-grown when sold.<\/p>\n<\/section>\n
