Catalogue Note

Blue John, sometime called Derbyshire Spar is a semi-precious mineral, a form of fluorite which was discovered over two thousand years ago by the Romans when they mined lead and other ores in the caverns of Castleton, Derbyshire. It was valued for its translucency, colours and overall beauty, especially in the 18th century.

The origin of the name 'Blue John' is still unclear. It is thought to have come from the French 'bleu-jaune', meaning 'blue-yellow.’ Referring to the stone’s blue and yellow colours, the name would have then been corrupted to ‘Blue John’ in English. Another theory is that the name 'Blue John' derives from 18th century miners who separated the stone from Zinc Sulphites, known locally as 'black jack.'
