Durability & Decay Resistance

Moderately durable; heartwood has some decay resistance, while sapwood is more susceptible to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$8–18 per board foot for ordinary kiln-dried walnut; grade, width, and region affect price.

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

Wood Age Estimate
Not reliably estimable from the image; no clear wear or oxidation indicators establish the sample’s age.

Common Uses

Furniture, cabinetry, flooring, veneer, turning, and musical instruments.

Geographic Origin

Eastern North America, especially the central and eastern United States.

Workability

Generally machines and sands well; sharp tools help limit tearout in figured or reversing grain. Glues and finishes readily.

Finish Recommendations

Use a clear oil, shellac, lacquer, or polyurethane; test first, since finish can deepen the brown color.

Notable Features

Walnut often has attractive dark heartwood and good dimensional stability; the pictured boards lack a uniquely diagnostic feature.
