About Green Moissanite Stones

Green moissanite is synthesized in a laboratory through a process known as "doping," which involves introducing impurities into the silicon carbide crystal structure during the manufacturing process. The specific type and quantity of impurities added determine the final color of the gemstone. For instance, incorporating small amounts of nitrogen can yield green or yellow hues.

Typically, laboratories follow these steps to create green moissanite:

  1. Silicon, carbon, and a specified quantity of dopant element (such as Cr) are heated to a temperature ranging between 1600°C and 2000°C.
  2. The heat causes the silica atoms to rearrange and forms crystals from the mixture.
  3. After cooling, the crystals are shaped and polished into various sizes.

Additionally, the color of moissanite can be influenced by the growth conditions. Exposure to superheated and pressurized gases can lead to trace elements of other gases being trapped within the stone's sealed chambers. These gases then interact with the carbon in the stone, resulting in a distinctive tint.
