Labradorite

Colorful labradorite is classified as a plagioclase feldspar along with moonstone. When you move the stone it has an iridescent blue billowy light that moves across its surface. This is calledshiller orlabradorescence in gemology.

The play of color in labradorite is most pronounced in larger specimens. Other colors it flashes besides blue are gold and green, and less frequently, red and orange.

Labradorite gets its name from its original discovery in Labrador, Canada. The variety of labradorite found in Finland is known as spectrolite. Most labradorite at the present time comes from Madagascar.
