Moissanite is a naturally occurring mineral composed of silicon carbide (SiC) that was discovered in 1893 by French chemist Henri Moissan in a meteor crater in Arizona. Initially mistaken for diamonds due to its brilliance and hardness, moissanite is now synthesized for various industrial applications and as a diamond alternative in jewelry. How Moissanite Is Made: Moissanite can be found in nature, but it is exceptionally rare. Most moissanite used in jewelry is lab-created through a process called the high-pressure, high-temperature (HPHT) method or the chemical vapor deposition (CVD) method. These processes involve growing moissanite crystals in controlled laboratory environments...
