Selenite is named for Selene, Greek goddess of the Moon because of its moon-like glow. Exchanged between lovers, it will bring about reconciliation.
Selenite crystals work to help you to bring light down from the higher realms into the physical body, to create personal transformation.

The white or transparent crystals have a strong vibration that may open the crown chakra and the soul star chakra.

This will assist you to contact the Divine Mind and to access the Angelic realm. These are high vibration crystals, that also deliver clarity of mind, by cleansing the aura of negative energy build-up, both within the physical and the etheric body.

Selenite holds no negative energy and does not need to be cleansed. Be sure to not get it wet!
