Grain Pattern

Mostly straight to mildly irregular, with subtle cathedral pattern and a small knot; appears flat-sawn/plain-sawn rather than figured.

Color & Appearance

Warm medium brown to chocolate-brown heartwood with lighter gray-brown sapwood and subdued luster. Walnut commonly lightens or develops warmer amber tones with age and light.

Hardness (Janka)

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful resistance to decay and insects, while sapwood is less resistant.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; premium clear or figured stock can 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 determined from the photograph; the surface appears relatively recent, with handling scratches but little established patina.

Common Uses

Furniture, cabinetry, flooring, doors, architectural millwork, gunstocks, veneer, and turning.

Geographic Origin

Native primarily to the central and eastern United States, especially the Midwest and Appalachians.

Workability

Generally machines, sands, glues, and finishes well, though knots and irregular grain may cause localized tearout. Pre-drilling is advisable for fasteners.

Finish Recommendations

Apply a film finish such as lacquer or polyurethane, or a penetrating oil followed by wax. Sand evenly and seal end grain; test finish because walnut can absorb unevenly.

Notable Features

Moderate weight, attractive brown color, good dimensional stability, and occasional curl or crotch figure; the visible knot is a natural feature.
