Selenite is a self cleansing, high vibration crystal that can not only cleanse itself but also other crystals and their inherited negative energies. 
A stone for clarity and guidance, selenite provides support to ‘clear your mind’, sharpen your awareness and allow you to see the truth by connecting you to a higher consciousness. Selenite brings strength in decision-making and heightens self-awareness. The gentle healing qualities of selenite can be used to provide protection from negative energy to create a safe and quiet space with a peaceful atmosphere.  Selenite is also commonly used for house gridding and protection.
