Hi all,

i just watched a Nature special on PBS about diamonds. The show claimed that diamonds were formed on earth a billion years ago from coal 100 miles deep in earth surface. Did we have carboniferous forests a billion + years ago to turn into coal? Maybe diamonds were part of the stuff floating around that the earth form from? or maybe the hot deep biosphere makes sense.

just some thoughts
