Color/Appearance: Peruvian Walnut tends to be darker than the species coming from North America or Europe, with a deep chocolate brown color. The wood will sometimes have a purplish hue, and may also contain streaks of lighter-colored wood mixed throughout the heartwood. When a finish is applied, the wood turns a very dark brown, (somewhat reminiscent of Wenge), and in some cases the wood turns almost black (see scans below).

Grain/Pore: Peruvian Walnut has a medium to coarse texture and medium-sized pores which may require filling for a smooth finish. The grain is usually straight, but can be irregular. Grain patterns and figuring such as curl seem to be much less common in the tropical species than in the temperate species.
