Nice shot. At the risk of sounding geeky, when are people going to stop referring to coal as 'black diamonds'? Black diamonds do exist but they're not what gets carried around in bulk trains to be burnt in power stations. Coal isn't even pure carbon and it certainly isn't crystalline, so IT basically bears about as much resemblance to a diamond as a bar of chocolate!
