Selenite is a very calming and protective stone, instilling a deep sense of peace and tranquillity; a large piece placed in the home is said to ensure a peaceful atmosphere.
It is also believed to be good for enhancing concentration, bringing clarity of mind and would therefore be a good "study" aid.
Selenite is also thought to aid connections with the angelic world.
