Chakra: Throat and Third Eye
Mineralogy: Blue John is massive fluorite, exclusive to Derbyshire. It shows distinct banding of purple with yellow or white, and sometimes green. Purple with yellow is the most common colour combination.History and Tradition: 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.
Healing Properties: Blue John shares the properties of rainbow fluorite and violet fluorite. However, it is more of an earthbound workhorse than violet fluorite – I mean that in a good way. It works its way through the physical body, cleansing, balancing and relaxing as it goes.
