Just letting everyone know that I voted for in the first round of mostly because I saw a lot of support for its rival that shall not be named and I'm a contrarian by nature.

We have crystals that formed in other stars! Dissolve some meteorites almost completely, and some of the residue is SiC -these grains have carbon and silicon isotopes produced in red giant stars and supernova; from before our solar system formed.

@MineralCup that is a cruel and unusual match-up. (I voted for because I feel like chaos this year.)

The first commercial LEDs were based on synthetic . 3H-SiC was used for yellow LEDs in and 6H-SiC was found to emit blue light. Unfortunately, SiC has an indirect bandgap, therefore nowadays, the more favorable GaN is used, which has a direct band gap and is about 100 times brighter.

I'll start some early campaigning for , because synthetic (SiC) is also super-interesting from a materials science perspective 🤩

Natural has a huge color variation from green and blue to black depending on composition. It was first identified in 1904 by Henri Moissan in a sample from the Canyon Diablo meteorite found near Barringer Crater.
