Grain Pattern

Predominantly straight to subtly wavy, with fine, moderately open texture; appears flat-sawn with mild cathedral effects and no obvious specialty figure.

Color & Appearance

Medium chocolate-brown heartwood with gray-brown variation and somewhat lighter sapwood; natural luster is subdued. Walnut commonly lightens slightly and develops warmer golden tones with age and light.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood offers fair decay resistance but is not a premier outdoor wood. Insect resistance is moderate.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; premium figured or wide stock may exceed $25.

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 this photograph; surface wear and oxidation suggest an older finished or handled piece, not necessarily old-growth wood.

Common Uses

Furniture, cabinetry, gunstocks, architectural millwork, veneer, turning, and decorative carving.

Geographic Origin

Eastern and central North America, especially the Mississippi Valley and Appalachian regions.

Workability

Generally machines, sands, glues, and finishes well; interlocked areas can tear out during planing. Pre-drilling is advisable for fasteners.

Finish Recommendations

Use a clear oil, shellac, lacquer, or polyurethane; sanding sealer helps produce an even surface. Avoid strongly amber finishes if preserving the cooler brown color.

Notable Features

Recognizable dark brown color, attractive aging, moderate density, and good dimensional stability; faint natural wood scent.
