Yep, I'm aware. I've always felt that the material should embrace what it is -- a crystalline material allowed by nature but manufactured by experts [1] -- rather than attempt to meet naturally-occurring gemstones on their turf. (Yes, crystalline SiC has been found in nature as moissanite, but it is exceedingly rare.) For some people, geologists in particular, there is a romance to the formation of a natural diamond due to heat and pressure within the earth. That's great too! [1] Look at your high-efficiency LED lights to find some SiC in your house. Thanks, Cree and others!
