Amethyst is an excellent stone promoting peace, spirituality and purification.  Amethyst clears and soothes the mind during meditation, raises your consciousness, and awakens your inner spirituality.  It is the stone of sobriety and helps the wearer find the root cause of such addictions both physically and emotionally.  As a result, it aids self-control and curbs overindulgence.  Amethyst also protects your personal and professional environment from toxic energies and creates a peaceful atmosphere.
