Estimated Market ValueNot an official valuation

Approximately $8–$15 per board foot for good clear domestic walnut; figured or exceptional stock may cost 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 this photograph; the dark patina and wear suggest a finished, used surface rather than necessarily old wood.

Common Uses

Furniture, cabinetry, flooring, architectural paneling, gunstocks, turned objects, and decorative veneer.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well, though grain reversal can cause localized tear-out. Predrilling is advisable for fasteners.

Finish Recommendations

Clean gently, then use oil, shellac, lacquer, or clear polyurethane; sanding sealer can improve uniformity. Avoid overly amber finishes if preserving the cooler brown tone is desired.

Notable Features

Characteristic dark color, attractive understated grain, good dimensional stability, and a smooth, refined appearance.
