Labradorite is a feldspar mineral that is most often found in igneous rocks. What sets the stone apart from other semi-precious stones are the multicolor streaks inside. The minor fractures within the stone reflect light in a way that is bounced back at different wavelengths. This reflection at varying wavelengths is what brings out the beautiful colors and give it the amazing iridescence. Lapidaries must do a careful study of the material so that the finished stone will be oriented to produce the best full “face-up color.” When cut correctly for proper angle, high quality material displays a bright flash of color(s).
Labradorite was first discovered in Labrador, Canada. The ancient Inuits there believed that Labradorite was the frozen fire of the Aurora Borealis.
