My SO and I seem to have agreed on getting a moissanite for the e-ring that is hopefully coming sometime in the next few months. 🙂
It’s not easy to find decent info on how moissanites are made– Charles and Colvard just says they are created using a “patented thermal growing process.”
Has anyone found good info on how they are made, or even on the thermal gem-growing technology? I’m curious about this stuff, and curious about the potential environmental effects of moissanite.

@Creiddylad: I don’t think anyone really knows how it is done, and I don’t think Charles and Colvard would share too much information so others cannot reproduce their technique.
All I know is natural silicon carbide forms very small, blackish green crystals. Then some laboratory voodoo makes it possible to create the larger, clearer crystals that can be cut into the stones used in jewelry.

I don’t believe you will find the specifics of the process anywhere online, because they are proprietary.

@Creiddylad: Do NOT quote me on this, but I assume it’s similar to the way other lab grown simulants are created? Look it up, there’s plenty of info available, just not on the brand name of Moissanite. They’re all created under some kind of thermal growing process. It’s not just something fancy that Cree invented.

@Aquaria: Thanks ladies! I guess it must be done using some kind of a process called hydrothermal synthesis– basically gem crystals can be synthesized by putting special chemicals in an autoclave and heating it up under high pressure. It involves solvents of some kind. Still, I imagine since it’s done on a relatively small scale to produce moissanite, it’s a lot less damagine to the environment than diamond mining (my primary concern). If anyone’s interested, here’s a Wikipedia page about that type of gem synthesis: Hydrothermal synthesis
