Labradorite is a popular and highly iridescent variety of the mineral feldspar.
A spectrum of colours can often be seen as light interacts with the stone from various angles.
The colours are caused by the reflection and scattering of light.
The finest labradorite comes mostly from Canada, Finland and Southern India.
Labradorite is often associated with the colours seen in the Northern Lights.
In Inuit mythology labradorite is believed to be the frozen fire of the Aurora Borealis (northern lights) trapped within the stone.
