Kyanite energy in a cork necklace
I like when people, and I, pick a stone because it caught the attention or intuition... after that it's all about searching the meaning and encountering the description that best is understandable at that moment - that's why I don't like writing "prescriptions".
Anyway, despite that, I will give you three general words about each crystal if it is of any help for you or just for your curiosity.
About the crystal or stone:
Kyanite (blue): archangel's Michael sword (protection), inner bridges, psychic ability.
