Labradorite is a feldspar mineral of the plagioclase series that is most often found in mafic igneous rocks such as basalt, gabbro, and norite. It is also found in anorthosite, an igneous rock in which labradorite can be the most abundant mineral. Lore of the Inuit peoples claims Labradorite fell from the frozen fire of the Aurora Borealis, an ordinary stone that transforms to the extraordinary, shimmering in a mystical light that separates the waking world from unseen realms.
Some people believe that labradorite has been used in treatment for eyes and brain disorders, to stimulate mental acuity, and to reduce stress and anxiety. Labradorite helps to lower blood pressure, reduces sensitivity to cold, and alleviates rheumatism and gout.
Labradorite is mostly found in Canada, Finland, India, Madagascar, Newfoundland, Australia, Russia, and Scandinavia.
