That mean nasty crystal had no right to be where that bloke found it. It had formed millions of years ago in a cave or cavity in the earth thousands of miles up stream and became dislodged by wind rain ,storms and earthquakes and travelled down the river dislodging other rocks and squashing water beetles and little fishes, maybe even blocking small channels to form erosion in the river banks and as it went and generally causing havoc to the micro environment.......Then millions of years later this bloke comes along and spots it in the creek , picks it up and takes it home and shoves it in a box thereby preventing this darstidly crystal from causing any further damage to the environment
