Grain Pattern

Flat-sawn slab with mostly straight grain, flowing cathedral patterns, small knots, and mild irregular/crotch-like figure; live edge visible.

Color & Appearance

Warm chocolate-to-cinnamon brown heartwood with lighter sapwood, subtle dark streaking, and moderate natural luster. Walnut generally lightens or turns more golden-brown with age and UV exposure.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has reasonable decay resistance and some insect resistance, but sapwood is perishable and outdoor exposure is not recommended without protection.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $12–30 per board foot for kiln-dried walnut slab material; premium figured or wide slabs may exceed $40.

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 date from a photograph; appears freshly milled or recently surfaced, with no substantial patina.

Common Uses

Furniture, tables, countertops, cabinetry, flooring, gunstocks, veneer, turning, and decorative slabs.

Geographic Origin

Eastern and central North America, especially the United States and southern Canada.

Workability

Machines and sands well, but knots and changing grain can cause localized tear-out. Glues, screws, and finishes reliably; dust may irritate sensitive users.

Finish Recommendations

Apply sanding sealer followed by oil, hardwax oil, lacquer, or polyurethane. Seal both faces and end grain; test finish because walnut can show blotchy absorption near sapwood and knots.

Notable Features

Distinctive walnut color, attractive figure, good dimensional stability, and occasional mild natural odor; dust can cause skin or respiratory irritation.
