Blue John Calcium Fluoride Mineral

Derbyshire Blue John is a rare type of fluorite.  This calcium fluoride mineral can only be found close to the village of Castleton in Derbyshire.

The blue, purple, yellow and white colour comes from films of oil that fell on the crystals many millions of years ago.
