Labradorite BriolettesLabradorite is in the feldspar family of minerals along with moonstone and sunstone. Labradorite originally came from the northeastern Canadian province of Labrador. Today it is found predominantly in Madagascar, though a prominent variety known as spectrolite is found in Finland. Originally Spectrolite was a trade name used only to refer to material from Finland. However, the term Spectrolite has been expanded to include Madagascar Spectrolite.
