Gents Blue John Jewellery

Blue John is a rare mineral, a variety of Fluor-Spar displaying a stunning rainbow of colours.

Numerous shades of blues, purples and yellows can be seen, creating a uniqueness within every piece of jewellery. Our Blue John originates from the historic mines of Castleton, Derbyshire, the only location on Earth that it has been discovered. Deep within the limestone, the Blue John is found as veins and nodules which are carefully mined by hand to ensure that the structure and bands of colour within it are preserved. Originally discovered in Roman times, Blue John is now a well loved gemstone within jewellery. It pairs very well with Whitby Jet so we often combine them within our jewellery to produce an attractive colour contrast between light and dark.
