A signature gents silver ring featuring a premium Blue John 10mm round stone. This ring is made in our Sheffield studio by designer Andrew Thomson and hallmarked in sterling silver. Available in most ring 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.
