Amethyst - Deep Purple from Uraguay
"Amethyst's inherent high frequency purifies the aura of any negative energy or attachments, and creates a protective shield of Light around the body, allowing one to remain clear and centered while opening to spiritual direction. 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."
One of the other properties of Amethyst is its ability to help stop negative patterns associated with addiction, negative choices, and emotional stagnation.
