Selenite is a form of crystallized gypsum and is very soft and fragile.
Its composition is hydrous calcium sulfate. It can be found in many
Crystal formations - most are striated with terminations that are
Either single extended points or a "fish-tail" configuration. The picture
Above shows two different crystal forms.

Selenite may be used to access past as well as future lives. Access
is provided by rubbing the crystalline structure with finger or thumb
(not nail). During this activation process, when the meditative state
is reached, the visual images will begin.

It is a Stone of serenity, peace, meditation and universal consciousness.
And offers spiritual guidance and promotes psychic powers, especially
mental telepathy.

Selenite heralds the approach of the marriage between spirit and
matter. In her books, Katrina Raphaell calls Selenite one of the
predominant power stones – and warns that, as such, to be sure that
you are prepared BEFORE USING.
