Meet the mystery diamond from outer space

It sort of sounds like it was pulled straight from an RPG but, celestial diamonds are a real thing. It is thought the mineral lonsdaleite was formed in the mantle of a dwarf planet.

From CNN:

Long before this discovery, scientists have debated the existence of lonsdaleite, Asimow said.
“It seems like a strange claim that we have a name for a thing, and we all agree what it is,” he added, “and yet there are claims in the community that it’s not a real mineral, it’s not a real crystal, that you could have a macroscopic scale.”
Scientists first identified bits of the mineral in 1967, but they were minute — about 1 to 2 nanometers, which is 1,000 times smaller than what was found in the most recent discovery, Salek said.
