The history of Labradorite in Norway,
Despite the apparent geological ties that its name suggests,
hailing from Newfoundland and Labrador in Canada, Labradorite can
actually be found in significant deposits in Norwegian rocks. It is
a member of the feldspar group of minerals, which crystallise in
magma in a wide array of shapes, sizes and, of course, colours.
It is this regionality that often leads people to mistake
Labradorite for what is known as Larvikite. This is primarily found
in and near the Larvik Fjord region, which is centred around a town
called Larvik in southern Norway, but it is a form of igneous rock
and not a gemstone. Larvikite rock rather contains feldspar
minerals that include Labradorite and they can often have a similar
appearance when it comes to the light that reflects off and
refracts around the gemstone surfaces.
It is for this reason that Labradorite is also often mistaken
for Black Moonstone, but they are not the same in geological terms.
The whole south eastern region of Norway around Langesund, which is
located slightly to the west of Larvik, is rich in Labradorite and
has consequently been a place of great fascination to geologists
and scientists for years. It's around 150km south west of the
capital of Oslo, so there has long been easy access to the mines
for those who have wanted to export it across the globe, spreading
the worldly fascination with an otherworldly gemstone.
