Labradorite is a feldspar mineral originally founded in Labrador Island, Canada around the 1700s. Recently, this mineral has become popular as more individuals have discovered it’s beautiful “flashing” color when shown under light; this iridescent coloring is known as “labradoresence”, named especially because it is a light phenomenon unique to the mineral. The mechanism of this color play is the result of light shining through the rock, striking what’s called a “twinning surface” and then reflecting off and thus producing the iridescent colors. The colors, which often compared to those of aurora borealis, are comprised of blue, green, golden yellow or purple shades, while the primary color of the rock is usually gray. Labradorite pieces that have all of these colors covering the whole surface are known as “spectrolite”, which is considered to be the highest quality of the stone, primarily found in Finland or Madagascar. Some religious groups in the northern hemisphere deemed this stone as “frozen fire” that had fallen down from the Northern lights, or as a stone on Earth that contained “fragments” of this spectacle.
