This beautiful, one of a kind bracelet is made out of the stone, Seraphinite. Seraphinite apparently acquired its name due to its resemblance to feathers, such as one might find on a bird's wing. With some specimens the resemblance is quite strong, with shorter down-like feathery growths leading into longer "flight feathers"; the resemblance even spurs fanciful marketing phrases like "silver plume seraphinite." Seraphinite is generally dark green to gray in color, has chatoyancy, and has hardness between 2 and 4. Seraphinite is mined in a limited area of eastern Siberia in Russia. Russian mineralogist Nikolay Koksharov (1818-1892 or 1893) is often credited with its discovery. The size of this beautiful bracelet is adjustable between 7" and 8".
