A beautiful Blue John stone set in hallmarked sterling silver handmade in our Sheffield studio by jewellery designer Andrew Thomson. The stones have been cut specially for this design. Available in two stone sizes.

As all stones are created naturally, each one is unique and may therefore vary from the image. However we guarantee they are of the highest quality and handpicked specifically for each design.

Blue John (also known as Derbyshire Spar) is a semi-precious mineral, a form of fluorite with bands of a purple-blue or yellowish colour. In the UK it is found only at Blue John Cavern and Treak Cliff Cavern at Castleton in Derbyshire. During the 19th century, it was mined for its ornamental value, and mining continues on a small scale. Deposits of fluorite have been recently found in China with colouring and banding similar to the classic Blue John stone.
