Labradorite is a mineral whose peculiarity of certain parts is to have bursts of metallic color called labradorescence. Green and blue are the most common colors, but we also find some with yellow, orange and even sometimes purple bursts. The best quality parts may have any of the colors of the spectrum. Labradorescence is due to interference in the mineral lamellae constituting the rock. Labradorite stone belongs to the feldspar family and is composed mainly of sodium, calcium, iron and potassium. This stone is formed in magmatic or metamorphic rocks.
