Labradorite is a rare feldspar mineral, a stone so unique the term ‘labradorescense’ was coined for the iridescent optical effect given by the stone when viewed at a certain angle against the light. The labradorecense is caused by light entering the stone and being reflected by a twinning surface. The colour seen by the observer is the colour of light reflected from within the stone.
The photos were taken in bright sunlight to bring out their best colours.
