Nigerian Ebony, or Gaboon Ebony, is a rather small tree that reaches heights no taller than 60' and no larger than 2' diameter. The heartwood is jet black, very hard, and very dense. It's an exotic wood probably most known for its use as fingerboards and keys for various musical instruments. It's also great for pens, bottle stoppers, knife handles and jewelry boxes. Ebony is the Greek word for "fruit of the gods". Historically drinking goblets were made from its wood, as they believed it was an antidote for poison, and its use would ward off their enemy's evil intent.
