Origin of Name & Mythology: Blue John may be a corruption of the French bleu jaune, meaning "blue yellow". The mines were worked from the early Roman period, when the stone was carved to make drinking vessels, and prized for the flavour it gave wine, which was in fact created by the pine resin used to stabilise the stone while carving. The mines fell into disuse, but were rediscovered in the 18th century.

Additional Information

Blue John shares the properties of rainbow fluorite and violet fluorite. It is more of an earthbound workhorse than violet fluorite, meant in a good way.

It works its way through the physical body, cleansing, balancing and relaxing as it goes.
