Blueberry Fluorite

I. The Metaphysical Reading

How the stone has been held.

Blueberry fluorite is worked with as a stone of concentrated study and orderly thought. Practitioners keep a cluster on the workbench during writing and research, and it is often paired with clear quartz when a project must move from wide reading into a single clean argument.

II. The Scientific Reading

What the lattice actually does.

Blueberry fluorite is a trade name for small deep-blue cubic fluorite crystals whose intense colour comes from lattice defects induced by natural radiation from surrounding uranium-bearing granites. The best material comes from the Erongo Mountain pegmatites of Namibia and from the Huanggang Mine in Inner Mongolia, China. The stone is soft and cleaves easily on the octahedron.
