Amethyst
Amethyst stimulates the Third Eye, Crown, and Etheric Chakras enhancing cognitive perception as well as accelerating the development of intuitive and psychic ability. It initiates wisdom and greater understanding and is a stone of comfort for those grieving the loss of a loved one.
 
Amethyst’s ability to expand the higher mind also enhances one’s creativity and passion. It strengthens the imagination and intuition and refines the thinking processes. It helps in the assimilation of new ideas, putting thought into action, and brings projects to fruition. Amethyst is also well-known as a talisman of focus and success.
 
Its a great stone for increasing psychic awareness, overcoming addiction, feeling through grief, adjusting to new transitions, and anything else that requires you to sort through hard things by going within yourself to heal the source of the discomfort.
