Amethyst is a stone of transformation and connection to Spirit. It is a good stone to use 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.
This stone can also be used for protection. It creates a high vibration atmosphere that nothing can penetrate but similar high vibration energies. I use amethyst to grid rooms where I do teaching or healing work.
