The mineral labradorite is a calcium-sodium-aluminum-tectosilicaat having the chemical formula (Ca, Na) (Si, Al) 4O8. It belongs to the feldspars. The colorless, white, gray or pale green labradoriet has a glass luster, a white stripe color, according to a perfect cleavage crystal plane [001], and a good according to [010]. The average density is 2.69 and the hardness is 7. The crystal system is triclinic, and the mineral is either radioactive or magnetically. The characteristic iridescence that labradoriseren is called, is caused when the light struck from microscopic crystals of various dark minerals that lie on the cleavage planes. Labradorite usually comes shapeless or grainy for; the mineral is rarely crystals. Labradorite is the precious gemstones that show some iridescence undoubtedly the best known. When the stone is judiciously cut, the play of colors is even better advantage. But also on the rough chunks can see the beautiful labradoriseren often. There are few minerals that change color as strong as labradorite. The name of the mineral labradorite is derived from the Labrador Peninsula in Canada, where it was first described. The stone was in 1780 on the east coast of the Labrador Peninsula discovered by a priest and named by him to the island. He found a large number of boulders with a striking gray color that changed when turning color in dark greens and shades. This discovery aroused great interest among scientists at that time and it was established that there was talk of a natronkalkveldspaat or plagioclase. Labradorite is a common feldspar in metamorphic and igneous rocks as pegmatite. It is part of deplagioklaas series (albite-anorthite). The type locality of labradorite is Canada's Labrador Peninsula. Deposits are found more in Australia, Madagascar, Mexico, Russia, the United States and Finland.
