Description
Any of trees of the genus Diospyros, with very dark, hard, heavy heartwood. These trees are native to Africa (black or Gaboon ebony, D.dendo), to India and Ceylon (D.ebenum), east India (Coromandel or Macassar ebony, D.melanoxylon), Sri Lanka (Calamander ebony, D.quaesita). Ebony's dense, smooth-grain wood has been valued from the earliest times and was imported to Egypt from Nubia and the Sudan (Kuhn 1986). It is extremely durable and resistant to rotting, fungi and powder post beetles. Ebony, even though it is difficult to work and carve, is valued for decorative items, inlay work, black piano keys, musical instruments, and tool handles. It is rarely found in large pieces.
Several other dark, heavy woods from unrelated species are also called ebony because of their color. These are: green ebony (Cocuswood), brown ebony (Coffeewood), blue ebony and Mozambique ebony (African blackwood).
