Labradorite

About Labradorite

Displays labradorescence - a stunning optical effect where bright flashes of blue, green, gold, and sometimes red appear when the stone is moved. This is caused by light interference in microscopic layers of different feldspar compositions. Discovered in Labrador, Canada in 1770. Spectrolite from Finland shows the full color spectrum and is the most valuable variety. The Inuit believed the Northern Lights were captured within labradorite. Madagascar is now the primary commercial source. It is a variety of plagioclase feldspar. The play of color cannot be replicated synthetically. It is popular in cabochons, beads, and carved objects. Large slabs are used as decorative building stone.
