Diospyros Blancoi...Mambolo. It is just one of many different types of Ebony
I found Mabolo.
All true ebonys are in the Diospyros genus, even the numerous persimmon trees growing on my property (American Ebony/White Ebony).
I love the fine grain, density, and the ability to polish the wood without adding finish. When turning black ebony wood (Gaboon, etc) I look for pieces with some brown streaks. Pure black ebony, when polished, looks exactly like plastic.
This is a TERRIBLE wood for you. Immediately pack up what's remaining and send it to me. I will dispose of it creatively.
BTW, I've read that every location and culture has some species they call "ironwood" in their language, a generic name basically meaning "hard wood".
