The Samurai Hannya Ring is a sterling silver ring carrying the Hannya, the horned mask used in Japanese Noh theater for a woman whom jealousy has turned into a demon. The mask is cut in relief across the face of the ring, horns rising from the brow and the mouth drawn open over bared teeth.A Hannya is carved to read two ways, angry when held level and grieving when tipped down, and the ring keeps both in the one face. That doubling is why the mask is tied to samurai lore, standing for feeling strong enough to change a person, worn as a symbol rather than a religious piece.
