Blue John

The History of Derbyshire Blue John

It is believed that around two thousand years ago Blue John was discovered by the Romans. There were supposedly two Blue John vases also discovered during the excavation of Pompeii.

During the 19th century, Blue John was made into items such as vases, goblets, and even tables in the finest stately homes such as Chatsworth House in Derbyshire and Buckingham Palace in London.

Then more recently in 2013 a 'lost' deposit was rediscovered and in 2015 a new Blue John vein was found and named the Ridley Vein named after the miner and it was the first new vein to be discovered in over 150 years. (See the BBC article for further information on the vein discovered in 2015). Each vein has a distinct colour banding of blue, purple, white and yellow. The Ridley Vein being the 15th type of vein. Other veins included the 'Old Tor Vein', 'Millers Vein' and the 'Treak Cliff Blue Vein' to name a few.

Over the years Blue John has become much rarer (the rarest mineral in Britain) and the mines are now limited on the amount they can extract per year.

You can take a guided tour of the Blue John Cavern which is a fascinating experience for both young and old alike.

It is also believed that Blue John has great healing powers, absorbing stress and neutralizing negative energies.
