Grain Pattern

Predominantly straight, fine-to-medium textured grain with subtle cathedral and mild waviness; appears flat-sawn or plain-sawn.

Color & Appearance

Brown-gray to chocolate-brown heartwood with darker streaking and little visible sapwood. Walnut commonly lightens or develops warmer amber tones with age and finish, with moderate natural luster.

Hardness (Janka)

1,010 lbf Janka; Medium.

Durability & Decay Resistance

Moderately Durable; heartwood has useful resistance to decay and insects, though it is not a premier exterior wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for clear kiln-dried walnut; premium figured stock 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 estimated from this photograph; the surface shows no definitive antique patina or wear evidence.

Common Uses

Furniture, cabinetry, flooring, architectural millwork, gunstocks, veneer, turning, and musical-instrument components.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well; interlocked areas can tear out during planing, and predrilling is advisable for fasteners.

Finish Recommendations

Apply a clear oil, shellac, lacquer, or polyurethane after thorough sanding; a clear finish preserves the brown color, while oil emphasizes grain and warmth.

Notable Features

Distinctive dark coloration, attractive contrast, moderate dimensional stability, and good turning and carving qualities; end grain is needed for stronger confirmation.
