Opals promote a sense of calm security, easing stress and depression, and encouraging one to stop brooding in order to better direct one’s thoughts and energies. They are antidotes to restless thoughts and racing minds that rehash the past or anticipate the future. Opals center the mind and are stones of happy dreams, particularly soothing for children and those who have always slept badly or had recurring nightmares with no apparent reason. Precious Opal relieves any issues a child may have with an invisible or imaginary friend, and is especially helpful before sleep if the child wishes the friend to go away at bedtime.A stone of protection, Opal is a marvelous shield to keep from absorbing other people’s negative thoughts and energies. Just as it uses interference and diffraction to produce its colors, it can also run interference around challenging people or situations that affect your mood or hurt your feelings. Opal can also provide a “cloak of invisibility” in circumstances where one does not wish to be noticed or needs to fade into the background. It is highly beneficial when venturing into dangerous places, or in shamanic work where stealth is required.
