Labradorite

Labradorite is a member of the plagioclase series of minerals that includes felspars. As the name implies, Labradorite was originally found on Paul's Island, in Labrador, Canada. It occurs in large crystal masses and shows a remarkable iridescence. This is the result of light refracting from crystals within the gemstones’ structure which form tiny right angle prisms. The result is a play of colours across the surface that constantly changes and shifts, making Labradorite jewellery highly desirable and extremely attractive. Gemstone quality varieties of Labradorite with a high degree of iridescence may also sometimes be called spectrolite, moonstone and sunstone.
