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 reliably determine from the photograph; the rough bark and surface wear indicate an unprocessed slab, not its age.
Common Uses
Furniture, cabinetry, flooring, veneer, turning, and gunstocks.
Geographic Origin
Eastern and central North America.
Workability
Generally machines and sands well, but knots, checks, and irregular grain can cause tearout. Pilot holes help with screws.
Finish Recommendations
Sand progressively and test on an offcut; oil or clear varnish/polyurethane enhances the brown color. Seal checks as needed.
Notable Features
Walnut commonly has attractive color variation and a subtle natural luster; this piece shows knotty, irregular figure.
