Blue John Stone is a rare, semi-precious mineral found at only one location in the world; just outside Castleton, in Derbyshire. The name Blue John derives from the French Bleu Jaune meaning Blue Yellow. It is a form of fluorite and was discovered as miners were exploring the cave systems of Castleton for lead.
Each Blue John stone is different - unique. However, at Ceirys, we try to match the colours and patterns of stones as closely as possible. Due to the fact that stones are 'cut" individually from a 'vein" they will differ. Some may appear semi-translucent. These points are what make the stones so valuable, rare and highly popular. They are often considered an investment with collectors sited all over the world!
