History of the Blue John stone
The origin of the name ‘Blue John’ is thought to have come from the French ‘bleu et jaune’, meaning ‘blue and yellow’.
Blue John is a very crystallised formation, and occasionally surface marks can be seen. This is not detrimental to the stone and in fact enhances its individuality. The origin of its blue colour remains uncertain.
The creation of the Blue John gemstone began when the Treak Cliff and Blue John caverns were formed as mineral solution settled in the cracks of limestone, driven up from the depths of the sea by volcanic forces around 250 million years ago.
There are records alluding to the mining of Blue John as far back as the 18th century. The stone was originally used to create decorative vases and various other ornamental items. By the 19th century, output had increased in the mines surrounding Castleton and the handcrafting of Blue John jewellery began.
Splendid specimens of Blue John stone can be found in important collections throughout the world. But despite its international appeal, the deposits in the hills surrounding Castleton are still the only known sources of the stone in the world.
Any raw extracts that are found are kept within Castleton for exclusive use by the local workshops.
