Labradorite, a plagioclase feldspar, was named after the peninsula of Labrador in Canada, where it was first found. It displays what is called labradoresence, which is caused by light being reflected by fine mineral lines in a lattice structure. Deposits are found in Canada, Australia, Madagascar, Mexico and the United States. The especially fine varieties of Labradorite are found in Russia and Finland, where it is also known as Spectrolite.

It is generally cut as a cabochon and used in jewelry as bead necklaces, brooches, rings and other more ornamental objects.
