Amethyst is a stone of transformation and connection to Spirit. It is a good stone to activate the 6th and 7th chakras. It assists one in opening to Source or Universal energy, gently and completely. Amethyst has a similar healing energy to flowers or flower essences, particularly roses.
I have just added some new smoky amethysts from Kenya. These crystals add a whole new dimension to the purpose of this stone. As I work with this energy, I can feel it pulling away all of the old "stuff" which keeps me from fully embodying the spiritual being that I Am (and all of us are). Truly a crystal for our times right now.
In the case of angels or points, Spirit Dancer will choose one for you. Prices are per stone.
