Blue John a Rare Beauty Blue John Stone is found nowhere in the world but amongst the rocks of Treak Cliff Hill, Castleton. Blue John Stone is now only mined in two caverns: Treak Cliff Cavern and Blue John Cavern. This mineral, a colour-banded form of fluorspar, is so beautiful that it has been prized for many hundreds of years. 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 by 18th century miners to separate the blue / purple stone from Zinc Sulphites, known locally as black jack . https://bluejohnstone.com/a-history-of-blue-john-and-treak-cliff-cavern/
