Labradorite is a type of plagioclase feldspar displaying a unique phenomenon aptly named labradorescence. This is caused by the interference of light within the layers of the stone. Colors show through in lustrous metallic tints, most often blue and gold, although specimens with a complete spectrum of colors are most sought after. Labradorite derives its name from where it was first found on the peninsula of Labrador, Canada. Metaphysically, labradorite is believed to help facilitate life transitions. Deposits are found in Canada, Madagascar, and Finland.
