Amethyst has a protective, purifying, relaxing effect, brings harmony and inner peace. It clears your mind and provides insight into your behavior and the choices you make. In doing so, it helps to recognize and leave bad habits and addictions behind. It also provides insight into emotional matters and can help to give certain experiences a place, which helps you to process emotional pain, trauma and loss and grief to the next stage. Amethyst creates a field of light energy around it which can clean and protect your aura and - if the stone is large enough - a space. It can open the crown and third eye making the stone suitable for people who want to start developing their intuition and spiritual skills. It also helps make contact with higher energies and guides and is a good stone to support meditation. Physically, amethyst has a positive effect on the brain and nervous system, bruises, headaches and migraines and sleep problems (such as nightmares).
