This is a 19 mm (0.75") in diameter hand carved bone bead of a coiled snake with two heads. The bead is beautifully detailed with large eyes, nostrils, scales, and decorative edging around the holes, all highlighted in brown ink. Asian characters (see photograph) appear on the side, which may be the name of the maker. Maker, country of origin, and age are unknown. The bone is either from a cow or an ox. In very good condition; appears never to have been used.
