Grain Pattern

Mostly straight, with subtle wavy/interlocked areas and a mild cathedral effect; appears flat-sawn or plain-sawn. No obvious figured defects.

Color & Appearance

Muted gray-brown to chocolate-brown heartwood with lighter streaking; sapwood is largely absent or blended. Walnut commonly lightens or becomes more golden-brown with age and finish.

Hardness (Janka)

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately Durable; heartwood has useful decay resistance, while sapwood is more vulnerable to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

About $8–$18 per board foot for ordinary kiln-dried walnut; exceptional figured or wide boards may cost substantially 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 determined from the photograph; the surface appears recently milled or lightly weathered rather than demonstrably antique.

Common Uses

Furniture, cabinetry, flooring, architectural millwork, gunstocks, veneer, turning, and premium interior joinery.

Geographic Origin

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

Workability

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

Finish Recommendations

Use a clear oil, wiping varnish, lacquer, or polyurethane after sanding; shellac can provide a warm seal coat. Test finishes because walnut can develop uneven absorption.

Notable Features

Moderate density, attractive brown coloration, fine-to-medium texture, and good dimensional stability; stronger figure is possible in premium boards.
