Labradorite, a grey stone with colourful flashes
Labradorite is a plagioclase feldspar. When turned towards the light, blue, green or golden flashes may appear on its grey base. This optical phenomenon is called labradorescence and is caused by fine layers inside the mineral.
Where labradorite is found
The name of the stone refers to Labrador in Canada, where labradorite occurs, for example, near the settlement of Nain. Strongly coloured varieties used for jewellery and decoration also come from Finland and Madagascar.
Labradorite in jewellery, past and present
The Inuit of Labrador used this stone as an ornament before Moravian Church missionaries brought it to Europe in the 18th century. The samples donated to the British Museum in 1777 included polished stones intended for brooches.
In jewellery making, labradorite is often cut into cabochons, that is, smooth stones with a domed surface on which the play of colours stands out. It is set in rings, pendants and earrings. Polished decorative items are made from larger pieces, and the stone is also used for interior panels.
