Walnut is one of the most recognized and requested hardwoods in the world, prized for its rich, dark color and its long-standing reputation as a premier furniture and cabinetry species.

The heartwood of walnut ranges from light brown to a deep chocolate brown, occasionally showing a purplish cast, while the sapwood is nearly white to pale tan. The contrast between heart and sap is pronounced but can be reduced through steaming, a common practice to improve overall color uniformity. Walnut generally has a straight grain, though occasional waves or curl can occur, with a medium, uniform texture. Small mineral streaks and occasional burl figure are natural characteristics that add character without compromising strength.
