Grain Pattern

Mostly straight to mildly irregular, with prominent dark growth-band lines and subtle wavy figure; appears flat-sawn or tangentially cut.

Color & Appearance

Warm chocolate-brown heartwood with lighter brown areas and faintly paler sapwood. Walnut develops a richer, somewhat golden-brown patina with age; the surface appears smoothly finished with moderate luster.

Hardness (Janka)

About 1,010 lbf Janka—Medium hardness.

Durability & Decay Resistance

Moderately durable: heartwood has fair decay resistance, while sapwood is more vulnerable to insects and rot; not especially weather-resistant untreated.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for common kiln-dried stock; figured or exceptionally wide walnut may cost substantially more.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Cannot be reliably estimated from a photograph; the finish and darkened surface suggest some aging, but not necessarily antique wood.

Common Uses

Furniture, cabinetry, flooring, architectural panels, gunstocks, veneer, turning, and decorative trim.

Geographic Origin

Eastern and central North America, especially the United States and southern Canada.

Workability

Generally machines, planes, sands, glues, and finishes well, though irregular grain can tear out; predrilling is advisable for fasteners.

Finish Recommendations

Use a clear oil, shellac, lacquer, or polyurethane after fine sanding; a clear finish preserves the brown color, while prolonged light exposure may lighten it.

Notable Features

Recognizable walnut color, dark growth lines, moderate weight, and attractive natural luster; figure can become more evident after finishing.
