Natural Moissanite can be traced back to the late nineteenth century. The term Moissanite comes from Dr. Henri Moissan, who discovered this mineral in an Arizona meteor crater in 1904. Moissanite (a kind of silicon carbide) is also called carborundum. Most of the moissanite on the market is natural moissanite dating back to the late nineteenth century. The term Moissanite comes from Dr. Henri Moissan in 1904. The mineral was found in the Arizona crater. Moissanite (a kind of silicon carbide) is also called carborundum. Most of the moissanite on the market is artificially synthesized. Natural Moissanite is very rare and only appears in craters. Its color is mostly dark green and black. It has been mainly used as an abrasive for many years. In recent years, it has been researched and developed for applications in the electronic field, such as light-emitting diode materials. At present, the color of synthetic moissanite in China is mostly I or below color grade I, and some moissanite has a light green hue. In 2017, the imported moissanite from the United States can reach about D color. The appearance of Moissanite is very similar to that of natural diamonds, which is difficult to distinguish with the naked eye. It is also a semi-precious stone whose physical properties are closest to natural diamonds. At first glance, Mossang is indistinguishable from diamonds, and even instruments can’t distinguish it, but a closer look reveals that Mossang’s colorful fire is stronger than diamonds. Tested under professional equipment, Mozambique's fire is 2.5 times that of diamonds. In terms of dispersion value, diamonds are 0.044 and Mossang is 0.104; in refraction, diamonds are 2.417, and Mossang is 2.65, and Mossang’s dispersion and refraction values u200bu200bexceed diamonds. In terms of Mohs hardness, diamond is 10 and Moissanite is 9.25, which is much higher than other gems. The internal structure, value, and appearance of Moissanite are strikingly similar to diamonds. Even if it is detected with a diamond pen, it will be judged as a diamond, which is difficult to distinguish. But Moissanite can shine brighter than diamonds, the fire is more stunning, and the price is only 1/10 of the diamond! The fire color of Moissanite can look so beautiful because of the physical, chemical and optical properties of its crystals. This gem has a very high refractive index of 2.65-2.69 (2.42 for diamonds), a dispersion index of 0.104 (0.044 for diamonds) and a gloss rate of 20.4 (17.2% for diamonds). At the same time, Moissanite has a Mohs hardness of 9.25, which is only lower than that of South African diamonds and higher than other gemstones. The high hardness makes it not suitable for squandering and cracking, and can be preserved forever. The above is the information about Moissan diamonds summarized by the author for you.
