I think that it is persimmon. Is it very hard and heavy? Persimmon has black streaks in the pith, and the center of knots will be black in some cases, especially small knots near the pith. Persimmon is in the ebony family, so that is the reason for the black streaks and knots.

Persimmon is semi-ring porous, like walnut, where the pores start off large in the growth ring and gradually get smaller. The grain of persimmon reminds me of a light grained walnut. The black that I see in some of the pics and the grain pattern lead me to persimmon. Does the wood really have black streaks and knots, or am I seeing things?
