Selenite is a protective stone.  It shields a person or space from outside influences and is used for good luck and protection. The powerful vibration of Selenite can clear, open, and activate the Crown and Higher Chakras and is excellent to clear energy blockages.  Try placing under your bed to alleviate pain by removing energy blockages. 
 
You can use to help charge other crystals.  Avoid getting Selenite wet and treat with care as it's very delicate.
 
Available in 2-3" sticks (Price is only for crystal.  Does NOT include smudge stick)
