Diamonds aren't stable and will eventually, over billions of years, decompose from their cubic molecular structure to carbon's more stable form, graphite, which has a hexagonal molecular structure.
Oh, here's another good gemstone related one!
Amethyst and citrine are both quartz varieties, and if the color source happens to be from traces of iron in the crystal lattice, one can be turned into the other. Heating amethyst can make citrine, and irradiating citrine can turn it into amethyst. This is because the only actual difference between the two is the valiance level of a specific election in the iron atom giving the stone its color.
So if i bake a piece of amethyst in my oven i get cutrin, or we are talking about much greater temperatures?
NGL I'm not very familiar with the technical details, but I know quartz is pretty temperature sensitive and starts to get damaged about 400F iirc
It's possible special conditions are needed to really succeed, like low/no oxygen or a long duration at a lower temperature.
But theoretically, the answer to your question is "yes"
That's cool AF :3
