Derbyshire Blue John (also known as Derbyshire Spar, or simply Blue John) is a semi-precious mineral, a form of fluorite with bands of a purple-blue or yellowish colour that was formed several million years ago. In the UK it is found only at Blue John Cavern and Treak Cliff Cavern at Castleton in Derbyshire.

During the 19th century, Blue John was mined for its ornamental value, and mining continues on a very small scale today as only a small amount of the semi-precious mineral is allowed to be mined each year. It is predominantly used to make Blue John jewellery.
