Grain Pattern

Mostly straight to moderately irregular, with broad cathedral-like figure and small knots; appears flat-sawn. No clear quarter-sawn ray figure is visible.

Color & Appearance

Medium chocolate-brown heartwood with lighter brown sapwood and subdued natural luster; walnut commonly lightens or develops warmer amber tones with oxidation and sunlight.

Hardness (Janka)

1,010 lbf Janka; Medium.

Durability & Decay Resistance

Moderately Durable: heartwood has fair resistance to decay and insects, but is not ideal for prolonged exterior exposure.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary clear walnut; premium wide or figured 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
Cannot be reliably estimated from a finished photograph; it appears relatively clean and recently finished, with no definitive antique patina.

Common Uses

Furniture, cabinetry, flooring, paneling, veneers, gunstocks, turned objects, and interior architectural work.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well; knots and changing grain can cause localized tear-out. Pre-drilling is advisable for fasteners.

Finish Recommendations

Apply a penetrating oil or dewaxed shellac sealer, followed by lacquer or polyurethane; test first because finish can deepen the brown color.

Notable Features

Recognizable dark heartwood, attractive cathedral grain, moderate dimensional stability, and good polishing response.
