Blue john is a form of fluorite with bands of purple-blue and yellow colours. It is found only at Blue John Cavern and Treak Cliff Cavern at Castleton in Derbyshire. During the 19th century, it was mined for its ornamental value, and mining continues on a small scale. The origin of the name 'blue john' is thought to have come from the French 'bleu et jaune', meaning 'blue and yellow'. Another theory is that the name 'blue john' was termed in the 18th century by miners to separate the stone from zinc sulphites, known locally as 'black jack'.
