The natural form of Moissanite is so rare it has never been used to make jewellery. However synthetically created Moissanite
in recent years has become more and more recognised as a alternative to Diamond, especially as in recent times as diamonds have provoked some ethical questions and many people now look for an appealing alternative.

Moissanite is the rare mineral form of silicon carbide which has been found in meteorites and in mantle derived igneous rocks.It is classed in the element group in both the Dana and mineral class. It crystallizes in the hexagonal system. Synthetic moissanite is used as a diamond simulant by lapidaries.

Moissanite has a higher refractive index than diamond, moissanite is the most brilliant of colorless jewels. Due to Its optical properties, moissanite has 10% more brilliance (light return from inside the jewel) more luster (light reflecting from the surface of the jewel)and more fire than diamonds.

Moissanite also has a lower specific gravity than diamonds, and is 13% lighter than diamonds by volume. These optical and physical properties translate to a physically larger gem of equivalent carat weight and clarity. While a 1 carat round brilliant cut diamond is typically 6.5 mm wide when cut to ideal proportions, a one carat moissanite should come out to be about 6.7 mm in diameter. Moissanite clarity is comparable to that of a VS diamond and its color can vary around I-J-K in the diamond grading scale.

Because moissanite and diamonds look similar and have a few similar properties, jewellery stores today market moissanite as the “other diamond”.

Careful attension needs to be considered when thinking of purchasing a Moissanite stone. Moissanite does have certain characterristics which make it easy to identify, but these are not always know by the consumer.
