Grain Pattern

Predominantly straight, moderately coarse grain with subtle cathedral/flat-sawn figure and occasional darker streaks; no clear special figure visible.

Color & Appearance

Brown to purplish-brown heartwood with lighter gray-brown areas; sapwood is not clearly separated. Surface appears oxidized and moderately lustrous, likely lightening or mellowing toward warm brown with age.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately Durable; heartwood offers moderate resistance to decay and insects, but exposed weathering is not its strength.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; premium figured or wide boards 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 dated from this photograph; the worn, oxidized surface suggests years to decades of exposure or use, not necessarily old-growth wood.

Common Uses

Furniture, cabinetry, flooring, paneling, gunstocks, turning, veneer, and decorative trim.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachian regions.

Workability

Generally machines, planes, sands, glues, and finishes well; intermittent grain may cause localized tear-out, and predrilling is advisable.

Finish Recommendations

Apply sanding sealer followed by oil, shellac, lacquer, or polyurethane; a clear finish preserves color, while light oil enriches contrast.

Notable Features

Moderate weight, attractive brown color, good dimensional stability, and characteristic walnut warmth; image does not show diagnostic end grain.
