Blue John is a variety of fluorite found only in the beautiful Derbyshire Peak District around the town of Castleton where it is mined and nowhere else in the world, making it unique . This material has been treated in pine resin to stabilise it.
The 22ct Freeform Blue John Cabochon is the product you didn't think you need, but once you have it, something you won't want to live without.
