Ivory is a shade of off-white. Its most common use is in the keys of a piano, but it is also used in many carvings and statues.
Ivory is a hard material most often taken from the tusks and teeth of animals. Elephant ivory is the most common, but it can also be taken from the hippopotamus, walrus and narwhal. Ivory is used in jewelry, furniture inlays, dominoes and false teeth. Ivory harvesting, however, is banned in most areas in order to prevent poaching of endangered species. A legal alternative to poaching is the retrieval of ivory from long-dead mammoths.
