Amethyst

Amethyst is a very versatile crystal. It is believed to aid spiritual awareness and creative thinking. It is a protective stone and is said to protect against psychic attack. Placing amethyst next to you while you sleep is said to reduce nightmares.
Amethyst is connected with the brow and crown chakras so is a good crystal to use while trying to connect with spirit.
In healing, it can be used to relieve headaches, release tension, relieve physical and emotional pain and help combat addictions. Can also be used to reduce bruising and swelling.
