Labradorite
Labradorite is a powerful stone that helps in recalling mystical, magical experiences.For protection--discourages others from tapping into your energy & draining you.
Used to work with nature spirits.
Labradorite is used for courage, clarity, and issues with co-dependency.
Some like to use this stone to heal mental confusion and indecision, as it allows one to make decisions easily.
This stone is also about transformation on all levels, it allows for easy changes to take place, especially good for those who fear change.
It also allows for us to understand ourselves on a deeper level, lets us know who we really are in a bold and distinct way.
Labradorite allows clarity to come into our lives.
