Legend has it that the Northern Lights were once stuck inside rocks on the Canadian coast until a brave warrior freed most of them by hitting the rocks with a spear. The rocks that were not hit, still have those Northern Lights within them, the cause of the beautiful iridescent quality labradorite possesses. Today, the most highly prized variety of labradorite still comes from Labradore, however some extremely valuable specimen also come from Finland, where labradorite is known as spectrolite. Spectrolite and labradorite are also sometimes known as moonstone, however experts are still not in agreement as to whether or not the stones are actually the same. Labradorite has a vitreous luster, and rates a 6 to 6.5 on the hardness scale. It is rarely mistaken for other gems, as its sheen is so unique. This sheen, or bright iridescence, is caused by the scattering or reflecting of light. When light is scattered or reflected by tiny intergrowths and suffers interference, this sheen is born, which is known as schiller. This gorgeous eye catching effect can be orange, green, yellow, violet, blue, or all of these colors at once. When all of these colors are displayed at once, the phenomenon is known as laboradorescence. When laboradrites are found, some may display a hint of this visual phenomenon, however most must be polished, to bring the full effect of this display out. Sometimes, stones with laboradorescence are called rainbow moonstone. There is also a new variation of the stone seen on the market more often these days. I
