The heartwood is dark brown, almost black. On the quartersawn surfacem fine pencil-thin, light tan lines interspersed with blackish-brown stripes make the surface appear as if it has been stroked by the fine claws of some wild jungle animal. On the tangential surface, the light lines show up as undulating streaks, like waves on the water. Orientation of the grain is an important consideration to show the wood at its best. Wenge is straight grained, and very coarse textured, similar to the slivers from bamboo flooring.
