Nogal is similar to Black Walnut only much darker in appearance, and it is more uniformly colored. Other than that Nogal is almost identical to Black Walnut, only it’s larger and more black than its American cousin. Nogal is found all over South and Central America and is commonly used as a substitute for Wenge. Like all walnuts, its grain patterns can range from wildly figured as shown in this photo to a mostly straight pattern. We try to select the most figured stock to make our dice from.
