Labradorite Stones are usually grey with a lovely play of colours known as 'labradorescence'. This occurs when the light refracts inside the Labradorite stone. Moonstone is a variety of Labradorite stone displaying a high degree of labradoescence. This beautiful effect may explain why Labradorite is said to be a 'bringer of light'. Use Labradorite stones for jewellery designs with a fantasy or mystical quality for stunning effects.
