Blue John is a form of fluorite banded in purple-blue or a yellowish colour, a hard semi-precious mineral. It is found near Castleton, Derbyshire, UK, where it has been mined since at least the 18th century, and apart from a similar banded fluorite recently found in China it is the only source of this particular banded fluorite. Blue-john is also a term sometimes used for skim milk or milk which is beginning to sour.
