The Labradorite owes its name to Johann Reinhold Forster, a German naturalist in 1780, inspired by the region of Labrador, province of Canada where the stone was discovered a few years earlier on the Peninsula of Paul.
The labradorite is a mineral of the group of silicates, a sub-group of the tectosilicates of the family of the feldspars as the stone of sun, thefeldspar or moonstone.
The special feature of labradorite is to possess a set of colors with metal shine. The blue and the yellow colors are the most present, some quality stones are lavishly inhabited by all the colors of the spectrum, they are named spectrolites. The phenomenon is the result of interference of the slats matched, called the effect-Schiller-adularescence, known to other members of the family of feldspars such as oligoclase.
The term" labradorescence, sometimes used, is incorrect.
