A-Z of Crystals - Blue John

Blue John is a rare form of fluorite mineral found only in the Blue John Cavern and Treak Cliff Cavern in Derbyshire.

It's prized for its unique banded patterns of blue, purple, and yellow hues. In terms of healing properties, it promotes emotional healing, clarity of mind, and spiritual growth. It is also thought to enhance wisdom and facilitate learning.

You can visit the Blue John mine and experience it for yourself.
