Difference Between Moissanite and Diamond

Moissanite vs Diamond

We all know about diamond, and women’s attraction and love for diamond jewelry. Diamond has been a preferred precious gemstone for making gold and silver jewelry items look brilliant. Because of its popularity among people, there have been many attempts to replicate it, or to make synthesized diamond in labs. Cubic Zirconia and Moissanite are two substances that look almost like diamond, and have the sparkle and brilliance to be used as a replacement for diamonds in jewelry. In fact, Moissanite is so close in appearance to diamond, that for an untrained eye, it is impossible to identify a Moissanite from a diamond. This article attempts to highlight some differences between Moissanite and diamond.

Diamond, which is in reality, a carbon, is the hardest known substance to mankind, and is also known for its sparkle and brilliance. These attributes of diamond have made them special in the jewelry world, and women have always been mesmerized by diamond studded jewelry items. No other gemstone can match the brilliance and shine of the diamonds. Diamonds are women’s best friends they say, and they are right as diamonds are very durable, and safe as a medium of investment.

There have been umpteen attempts to replicate the diamond in the labs, but none has been so successful, as those with Moissanite. In the early 20th century, Dr. Henry Moissan found traces of an extremely brilliant material in a small meteorite, in Arizona. It was silicon carbide, a naturally occurring material, but found in traces only in the world. This was the mineral that was almost like a diamond, but was not found in sufficient quantities in the world. It was painstaking research by scientists that finally a stimulant of diamond was produced in labs, and was called Moissanite in honor of the Nobel Prize winner scientist, Dr. Henry Moissanite. It is today being used as a replacement of diamond in jewelry, and provides more fire, brilliance, and luster than real diamond, at a fraction of a cost. Scientists have been able to create Moissanite in various shapes and sizes to be used as a gemstone in jewelry.

In brief:

Difference between Moissanite and Diamond

• The properties of Moissanite can be compared with diamond, and it has been found that this wonder material outperforms diamond on nearly all counts.

• If refractive index of diamond is 2.42, Moissanite has a refractive index of 2.65-2.69.

• Dispersion, also called fire by jewelers, is higher for Moissanite (0.104) than diamond (0.044). Even in luster index, Moissanite (20.4%) is much ahead of diamond (17.2%).

• It is only in hardness that diamond is ahead of Moissanite, but that too is just a little bit.

• Diamond has been given a perfect 10 on Mohs scale, whereas Moissanite is given 9.25.

• When it comes to toughness, Moissanite is labeled as excellent, whereas diamond is given a good on this count.

• Moissanite is also comparable to diamond in specific gravity.

    I only just found your article, and I need to correct you on a few things. The person who discovered Moissanite was Dr Henri Moissan, not Dr Henry Moissanite. The synthesis of Moissanite was not an attempt to create a synthetic Diamond. Moissanite is a naturally occurring stone that has very little presence on earth, because it is not an earthly stone. The conditions of our solar system are not right for Moissanite crystals to form, no exceptions. all natural Moissanite that is found comes from extra solar sources. The reason why Moissanite was first synthesised was as an abrasive powder, not as a gemstone. Moissanite is often found as inclusions in diamond. 99% of natural Moissanite is not large enough nor good enough quality to use as a gemstone. If you do happen to find a large enough natural Moissanite that is of gem quality, you will be paying 2 to 3 times the price for it than what you would do for a diamond of the same size and quality, this is why efforts were made to produce synthetic Moissanite of gem quality. Not as a Diamond simulant. Diamond does not have much in the way of “fire”. Diamond has a lower refractive index, roughly .2 to .3 less than Moissanite, and also has a lower dispersion, which is less than half that of Moissanite, .104 compared to the .044 of Diamond. Diamond has a hardness of between 9.5 and 10 on the Mohs scale, depending on purity. Moissanite has a hardness of 9.25 to 9.5. It is the second hardest stone in nature. When compared next to each other Diamond looks positively dull and boring, which is why I will never made Diamond jewellery. Please stop trying to compare them.
