Unfinished Walnut is a hardwood species you just don't come across everyday. The beautiful color tones along each plank make it a real eye-catcher amongst other unfinished hardwood species.
The color difference between its sapwood and heartwood is very pronounced, thus the significant variations in color and grain between boards. Walnut shows minimal color variation when exposed to intense light. Unlike other species, walnut tends to lighten over time. Walnut's sapwood is creamy white and sometimes tan, with heartwood ranging from rich dark brown to purplish black.
