Our Oia bookends showcase the unique hues and swirls of green onyx marble. Cut, ground and polished by hand, the stone boasts green, white and brown whorls and veins that vary in tone from translucent to saturated. Use the pair together to bracket and support favorite volumes—we love the way the stepped structure echoes the rhythm of book spines—or display them on their own on your bookshelf as fascinating sculptures. Due to the natural material, each bookend is one of a kind.
