This beautiful blue john bangle is handmade in our workshop in Sheffield.
The size of the stone is 25mm x 10mm and set in hallmarked 925 sterling silver.
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.
Now a little bit about the stone...
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.
