Lore of the Inuit peoples claim Labradorite fell from the frozen fire of the Aurora Borealis, an ordinary stone that transforms to the extraordinary. The stone, usually gray-green, dark gray, black or grayish-white, is composed in aggregate layers that refract light as iridescent flashes of peacock blue, gold, pale green, or coppery red. Labradorite is beneficial to the lungs, and may assist with respiratory problems, bronchitis and colds. It assists in digestion, regulation, and metabolism. It has been used in treatment for brain disorders, to stimulate mental acuity, and to reduce stress and anxiety. It may also be soothing during menstruation, for PMS symptoms, and for pain relief.
