Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for clear kiln-dried walnut; figured or premium grades 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
The image cannot establish tree or sample age; the clean edges and limited patina suggest a relatively recent cut or well-preserved blank.

Common Uses

Fine furniture, cabinetry, flooring, gunstocks, interior trim, veneer, turning, and decorative boxes.

Geographic Origin

Eastern and central North America, especially the United States Midwest and Appalachians.

Workability

Generally machines, sands, glues, and finishes well, though localized grain may cause modest tearout. Predrilling is advisable for screws and nails.

Finish Recommendations

Apply a penetrating oil, shellac, lacquer, or clear polyurethane after sanding; seal end grain carefully. Clear finishes best preserve its color and depth.

Notable Features

Stable, attractive brown color, moderate density, and good dimensional stability; the pictured piece has restrained figure rather than dramatic curl or crotch figure.
