slew writes "Unlike its more famous carbon cousins: diamonds and fullerenes, you've probably never heard of M-Carbon, but this form of compressed graphite which is as hard as diamonds has baffled researcher for half a century. Over the past few years, many theoretical computations have suggested at least a dozen different crystal structures for this phase of carbon, but new experiments showed that only one crystal structure fits the data: M-carbon."

Could be interesting tool material (Score:1)
This could make for an interesting tool material, especially as its harder than diamond and could be cheaper to make in time.
Also makes me wonder - will there be a new material discovered if they compressed supercooled carbon?
