Amethyst is a meditative and calming stone which works in the emotional, spiritual, and physical planes to provide calm, balance, patience, and peace.
Amethyst is used as beneficial when dealing with legal problems and money issues, which can lead to prosperity and abundance, though it is not the best known prosperity stone.
In the psychic and spiritual realms, amethyst is an excellent all-purpose stone that can increase spirituality and enhance intuition and psychic powers of all kinds. It does this by making a clear connection between the earth plane and other planes and worlds. Amethyst is also excellent for meditation and lucid dreaming. It is used to open one's channels to telepathy, past life regression, clairaudience, clairvoyance, and communication with angels. Amethyst also protects against psychic attacks, especially during spiritual work.http://meanings.crystalsandjewelry.com/amethyst/
