Selenite crystals are considered to be remarkably peaceful. 
By simply keeping this wonderful crystal in your presence its color alone will help to ground you.

 They carry and embrace high-frequency vibration, which is excellent in cleansing and clarity of the mind along with a deep sense of internal peace.

Selenite belongs to the class of gypsum mineral, which is extensively cleaned and named after the Greek goddess of Moon.

* Unlike other crystals, which require regular cleansing with either specially prepared aura sprays, sunlight, or charging through water, selenite is said to cleanse itself on its own.*
