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.
Beside blue and green, labradorite also occurs as yellow gemstones. The semi-precious yellow stones are a close cousin of andesine, which may also be yellow gems, as well as red, in which color andesine is reportedly enhanced labradorite.
