Ebony is a very deep black derived from various tropical trees of the genus Diospyros. The wood comes from tropical and subtropical trees in southern India and Sri Lanka. The word "ebony" itself is commonly used as a synonym for the color black.
Ebony has a very smooth finish when polished, and for that reason it is often used to create ornamental objects such as chess pieces, cabinetry and piano keys. The deep black wood is occasionally tinged with olive undertones.
Due to unsustainable and/or illegal harvesting practices, many ebony-yielding species are now severely threatened, particularly in the country of Africa.
