Labradorite is a plagioclase with an intermediate composition between the anorthite-albite series. It was first found in Canada off the east coast of Labrador, hence its name. It has a particular optical phenomenon of iridescence, known as labradorescence, in fact, by rotating the mineral, it shows various colors. This effect is due to the presence of various laminar layers within the mineral.
