Diamonds aren't quite as useless as bitcoin currently. Bitcoin - as far as I'm aware - is currently mostly used for speculation. Whereas diamonds are very useful in many industrial processes which require hard materials (think cutting/grinding tools). One could argue that diamonds are considerably more useful than bitcoin, most of the world's diamond consumption is for industrial use rather than jewelry.
