Labradorite is one of my favorite gemstones. It is a type of feldspar, found originally in Labrador, as you might have guessed! The parallel arrangement of its molecules causes it to act like a diffraction grating, and disperse light in such a way as to produce irridescence, or what they call "labradorescence". (You have seen this effect on the surface of a compact disc). These beautiful AA labradorite stones alternate with cobalt blue Czech glass beads. They are strung on a strong stretch cord, with a very nice pewter dove charm attached. The internal circumference is 6.5 inches and it should fit the average woman's wrist.
