Moissanite is a kind of Mosan diamond, also known as synthetic silicon carbide. Moissanite, also known as synthetic silicon carbide, is a gem very similar to diamond. This kind of gem is very similar to diamond in appearance, optical and physical properties, and is often used to replace diamond. Moissanite's hardness is second only to that of diamonds, reaching 9.25, which is much higher than other common gems, such as rubies and sapphires.
Moissanite's internal structure, numerical value and appearance are very similar to natural diamonds, which makes moissanite a popular substitute in the jewelry market. In addition, the refractive index of moissanite is higher than that of diamond, and the fire color is 2.5 times that of diamond, which makes moissanite shine more brightly in the light.
