An Amethyst Tumblestone is a very powerful and protective crystal. It guards against Psychic attack and also blocks geopathic stress.
Amethyst relates to the crown chakra and as a result is useful for achieving higher states of consciousness and also in meditation. It is very much a spiritual crystal and it enhances spiritual awareness.
You do not have to cleanse Amethyst as you need to do with other as it is self-cleansing.
