Amethyst has been highly esteemed throughout the ages for its stunning beauty and legendary powers to stimulate, and soothe, the mind and emotions. It is a semi-precious stone in today’s classifications, but to the ancients, it was a “Gem of Fire"; a Precious Stone worth, at times in history, as much as a Diamond. 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.
