Labradorite

Labradorite is the plagioclase feldspar ad in the same family as albite. Labradorite has been found in some meteorites.
Gem quality labradorite is known as spectrolite; which is a colorless variety, darkened with needlelike inclusions, it is often called black moonstone. Spectrolite is a dark and opalescent blue with a shimmer when the light hits it. It was discovered in Finland during WWII, and it is also called falcon's-eye.

According to an Eskimo legend, the Northern Lights were once imprisoned in the rocks along the coast of Labrador. It is told that a wandering Eskimo warrior found them and was able to free most of the lights with a mighty blow of his spear. Some of the lights were still trapped within the stone, and thus we have today the beautiful mineral known as labradorite.

Labradorite which shows an iridescent play of colors is used in jewelry and lapidary items, and as an ornamental stone it has many popular uses such as in decorative clock faces, table and counter tops, facing for buildings, etc..

Labradorite was originally discovered in on St. Paul Island, Labrador, Canada in 1770. Pieces of the stone were found amongst the artifacts of the Red Painted People of Maine. Spectrolite was discovered in Finland during World War II. It is considered to be the gem quality of Labradorite.

The name labradorite comes from the province of Labrador in Canada, which is a famous locality for labradorite with an iridescent play of colors. Feldspar is derived from the German word feld which means field. Iridescent labradorite is sometimes referred to as spectrolite.

Spectrolite, the most valued type of labradorite, hails from Finland. The name is derived from Labrador which is the main and original source of the Canadian variety of this feldspar stone. Labradorite is also found in India, Madagascar, Newfoundland, and Russia
