    Diamonds are cool. Not as engagement rings, but as ultra-dense carbon.

    They’re arguably the hardest known substance in the universe. The only things that might be harder are so rare that their hardness can only be tested in simulations. That makes diamond unequaled for cutting. They also have amazing thermal conductivity. All that from a transparent rock is awesome.

        To each their own, I don’t really care how they look (other than being transparent), I just think it’s cool that something that looks like glass is stronger than steel.
