Labradorite is a gemstone - a type of soda-lime plagioclase feldspar. It is usually blue-gray or gray-white with blue-green annealing in reflections of these colors, so-called irrigation. Reminiscent of peacock feathers.
For centuries, Labradorite has been believed to help treat colds, relieve painful periods, correct hormonal imbalances, eliminate stress, and lower blood pressure. It also allegedly promotes the development of intuition, suppresses fear and nervousness, and strengthens its wearer.
