The trees today are few and far between, and of a much smaller size then 20 year ago, found on the Asian, Indian and African continent. They can grow to 50′ in height & 1 1/2′ around, but you’re talking about a tree over 100 years old. The Gaboon Ebony wood can be also referred to as “African Ebony” and does infact come predominately from Africa. Today it is getting more difficult to get the pure black ebonies of the world, and instrument makers are sometimes resorting to dying the wood to improve colour consistency, or finding synthetic substitutes.
