Purple Selenite

I. The Metaphysical Reading

How the stone has been held.

Purple selenite is used the way plain selenite is — for clearing a room, resetting an altar, and keeping a bedside space feeling uncluttered — with practitioners adding a note of quietness to the crown for the violet material. It is kept dry, and treated as a tool rather than a talisman.

II. The Scientific Reading

What the lattice actually does.

Selenite is the transparent crystalline variety of gypsum, hydrated calcium sulfate, which precipitates when saline waters evaporate in basins and sabkhas. Faint violet tints come from trace impurities and from natural irradiation of the crystal lattice; much intensely coloured 'purple selenite' on the market is dyed. At a hardness of 2 it can be scratched with a fingernail, has one perfect cleavage that peels into sheets, and is slightly soluble in water, so it should never be washed or left in damp air.
