Ebony is a dense black/brown hardwood, most commonly yielded by several species in the genus Diospyros, which also contains the persimmons. Ebony is dense enough to sink in water. It is finely-textured and has a mirror finish when polished, making it valuable as an ornamental wood. The word ebony comes from the Ancient Egyptian hbny, through the Ancient Greek ἔβενος, into Latin and Middle English.
