Amethyst is one of the best stones to use for relieving tension and developing patience due to its calming mental effect. Ancient traditions held that genuine Amethysts were ruled by Saturn and focused the planet's energy to protect travelers against danger, clear mental unrest, bring luck to gamblers and prevent intoxication.
It is a favorite stone to use for meditation as it is believed to initiate wisdom and greater understanding and is thought to purify and amplify all healing rays.
Stone Power by Dorothee L. Mella states that an Amethyst will aid in the relieving of headaches and stimulates intuitive awareness. Wear an Amethyst if you want to get in touch with your intuition, your own feelings or your own values. Wearing this gem near the heart should help with purifying the blood and calming the heart. It is the February birthstone and a traditional stone to give for a sixth anniversary.
