What is Moissanite? |
---|
Moissanite is a silicon carbide that looks just like diamonds or CZ's but is not. Moissanite grown in laboratories is now being cut as gemstones and they are used as diamond simulants. Moissanite brings to the jeweler's table a similar index of refraction and better than twice the fire of diamond, but is only slightly less expensive due to the difficulty in growing the crystals. Moissanite is causing quite a stir in the jewelry markets. As a diamond simulant, artificial moissanite is very hard to differentiate from diamond and can fool many gemologists. It does have many similarities. It is very hard at 9.25 (diamond is 10) and it is highly refractive with an index of refraction of 2.6 - 2.7 (diamond's IR is slightly lower at 2.42). Most important, moissanite and diamond are thermally conductive unlike other diamond simulants and unfortunately it is this property that is used as the test for the authenticity of real diamonds. Differences however are clear and other tests can be used to differentiate the two. First of all, moissanite is hexagonal, not isometric and therefore it is doubly refractive unlike diamond. A close look at moissanite gemstones should show double facet edges whereas diamond's cut edges are singular in appearance. Moissanite is also slightly less dense than diamond and is rarely perfectly clear of color, having pale shades of green. Also natural flaws are absent in moissanite replaced instead by tiny, unnatural, white, ribbon-like structures that are a result of the growing process. The synthetic SiC known as carborundum has seen many uses in hightech ceramics, electrical components, abrasives, ball bearings, semi-conductors, extremely hard saws and armor. Natural moissanite is very rare and is limited to iron-nickel meteorites and a few other rare ultra-mafic igneous occurrences. Initially there were skeptics to the original meteorite findings and were attributed to the silicon carbide blades that may have been used to saw the type specimens. But this has been disputed because Dr Henri Moissan did not use silicon carbide blades to prepare the samples. There are several phases of SiC. The original mineral discovered is officially known as moissanite-6H. The (6H) refers to the hexagonal symmetry of this phase of moissanite. There are two other phases recognized as minerals: moissanite-5H and the isometric phase beta-moissanite. Moissanite is classified as an element dispite the fact, that in chemical reality, it is a compound! The reason for this is that the elemental bonds that exist between carbon and silicon are very similar to the carbon-carbon bonds of other elemental minerals such as diamond. |
