Labradorite is a feldspar mineral known for its stunning iridescence, called labradorescence, which flashes colors like blue, green, gold, and purple as light hits internal twinning surfaces, creating a "fire" within the stone. This stone is beautiful! It has linear lines through it that separate some of the colour - which makes it stand out so much more! This stone flashes all colours - yellow, blue and purples. Stunning! Named for its discovery in Labrador, Canada, it's a popular gemstone, often cut into cabochons to showcase its color play.
