Labradorite is a tectosilicate mineral also known as feldspar minerals. These minerals take up about 60% of the Earth’s crust. Feldspars are usually formed and crystallized in lava, although these minerals can also be found in form of metamorphic and sedimentary rocks. Labradorite is also a member of the plagioclase series. This fascinating mineral can be found off the coast of Canada in Labrador. Other sites have been found in Norway and numerous other locations across the planet.
Labradorite is calcium-wealthy mineral that is admired for the so-called schillers effect, a rich display of lustrous colours, where blue is prevailing on the surface. This phenomenon is also known as labradorescence, is caused by the light entering the mineral and bouncing back and forth within the mineral. When a mineral is displaying an enormous amount of labradorescence, are called spectrolites. Although not so rare, this particular phenomenon is not exhibited in all Labradorite minerals. If minerals do not display labradorescence, that doesn’t make them any less desirable. Other than labradorescence, there is yet another phenomenon called avanturescence. This as well a bright display of colour, which illuminates from the crystal,
Labradorite is a very prominent mineral, cut and shaped in cabochons and beads. Also statues are sculpted and polished from large chunks of Labradorite.
Labradorite is a very rare mineral within mass produced jewellers. It’s seen most in the hands off designers that will sculpt this fine gem into something marvellous.
Labradorite is found in form off igneous, metamorphic and sedimentary rocks, it is most commonly in a igneous rock formation acting as gabbros, basalt and norite.
