...and...A closer look with an array of instruments revealed two totally new kinds of naturally occurring carbon, which are harder than the diamonds formed inside the Earth.
"The discovery was accidental but we were sure that looking in these meteorites would lead to new findings on the carbon system," said Tristan Ferroir of the Universite de Lyon in France.
And no, there was not a male infant inside the meteorite upon it's descent the Earth. ;)"The only evidence we have for a higher hardness than diamond is the fact that we polished the rock section with a diamond paste and that our polymorph and polytypes were not polished by this material," said Ferroir. "This why we do think that its hardness is harder than diamond."
- More science about harder-than-diamond substances that, frankly, makes my head hurt.
- More background on how diamonds are formed in hot, high-pressure situations like volcanoes, meteorites, and annual employee reviews.
