I. The Metaphysical Reading
How the stone has been held.
Green fluorite is worked with as a stone of quiet mental order, kept on the desk during study, editing and long problem-solving. Practitioners hold that it clears cluttered thought without dulling the emotion attached to the work.

II. The Scientific Reading
What the lattice actually does.
Fluorite is calcium fluoride crystallising in perfect isometric cubes with four-directional octahedral cleavage. Its colour depends on trace rare-earth elements (yttrium, cerium) and lattice defects produced by natural radiation from nearby uranium- or thorium-bearing minerals. Green fluorite typically owes its colour to samarium substitution plus colour centres that can be bleached by heat and regenerated by radiation.
