I. The Metaphysical Reading

How the stone has been held.

Named for Selene, goddess of the moon. Traditional use frames it as a self-clearing stone - placed alongside other crystals to reset them, or held during meditation to quiet mental static. Never immersed in water, as the mineral dissolves.

II. The Scientific Reading

What the lattice actually does.

Selenite is the transparent, cleaved variety of gypsum. Its perfect single-plane cleavage produces the paper-thin, flexible sheets used historically as window glazing. The Cave of the Crystals in Naica, Mexico, contains selenite beams up to 11 metres long - the largest natural crystals ever documented.
