Well, it's more natural than something like a lab diamond. This one forms naturally given unnaturally created, but not completely implausible, conditions. There is a big difference between "we blew up rocks and they formed this mineral" and "we treated rocks with X acid and Y acid and then carefully annealed them under extreme pressure and they formed this mineral"

We’re a product of nature, it’s mistaken to believe we are above nature or that nuclear weapons aren’t also part of nature.

We’re also very much dependent on nature and natural forces.

So everything we do is, even if many steps removed, still an act of nature.
