About Derbyshire Blue John

The History of Blue John

It is believed that around two thousand years ago Blue John was discovered by the Romans. There was 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 more rare (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 neutralising negative energies.


Caring for Blue John jewellery

Whether your Blue John is set in silver or gold jewellery, care must always be taken as it is a delicate stone (on the Mohs scale). Avoid contact with silver cleaning solutions, perfumes and hairspray etc and it should not be worn when swimming or washing.

Made from blue banded fluorite (also known as Feldspar) this gemstone is 4 on the Mohs scale which means it is a very delicate stone and great care should be taken when wearing it especially rings. 

Our Blue John Jewellery

Our Blue John jewellery is mainly set in sterling silver with a selection of products in 9ct yellow gold, however all of our designs are available to order in silver, 9ct or 18ct yellow, white or rose gold. Blue John is renowned for its banding stripes but it can vary greatly from very dark blues, to purples to yellow, white and even brown. Blue john is a crystallised formation and therefore sometimes marks can also be seen on the surface of the stone

Please note: Blue John varies greatly and the colours of the product may vary to the images shown on our website. If you have any questions please contact us and we can email you an image of the stone before you order it. Here are a few examples below...
