Found only in the caverns deep below the Derbyshire Peak District village of Castleton, the Derbyshire Blue John gemstone is one of the world’s rarest minerals. Mining Blue John is essentially done by hand. Blasting is resorted to in only rare exceptional circumstances, as the shock can often disturb the crystalline structure and in some instances has also been known to shock the distinctive colouring and banding out of the stone, rendering the fluor-spar an off white opaque colour and incapable of being worked. It is the unique colouring and banding which adds to the prized value of the stone.

Often the Fluorspar occurs in veins surrounded by limestone needing a more complex process to remove them. Wedges and crowbars are carefully driven into the bedding plane beneath the deposit before the entire piece can be carefully removed and the true size of the find is only then discovered.

The precise quantities mined in any given year are unknown, but the leases in 18th century restricted output to 20 tons per annum. By 1892, the output is said to have been limited to 3 tons per annum. Today, production is running at approximately only half a ton per annum, of which is mainly worked and transformed into stunning unique pieces of jewellery.
