Three beautifully polished iridescent labradorite stones from our collection of rocks and minerals.
As light reflects off crystals beneath the surface of this stone, a spectrum of colours can be seen. This optical phenomenon is known as labradorescence or schiller. The colours we see are not in the stone but are the reflection of light.
Being highly polished each labradorite stone is exceptionally tactile.
Labradorite was discovered approximately two hundred years ago on the eastern shore of the Labrador coast of Canada. The stone initially looked rather dull and interesting but when moved, impressive blue and green hues were seen.
Analysis showed the play of colour was caused by the refraction of light from microscopic crystals of various dark coloured minerals within the stone.
