Grain Pattern

Mostly straight to gently wavy, with subtle cathedral and ribbon-like variation; appears flat-sawn and finely textured.

Color & Appearance

Medium to dark chocolate-brown heartwood with lighter brown streaking and subdued luster; walnut commonly lightens slightly and develops a warmer amber tone with age.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has fair resistance to decay and insects, while sapwood is less resistant. Not intended as an outdoor-weathering identification.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried lumber; figured or exceptional stock may cost 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 finished surface; apparent wear suggests an older finished component, not necessarily old wood.

Common Uses

Furniture, cabinetry, flooring, gunstocks, veneer, turning, and musical instruments.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well; tearout can occur in reversing grain, and sharp tools are recommended.

Finish Recommendations

Apply a clear oil, shellac, lacquer, or polyurethane after thorough sanding; test first because finishes can significantly deepen the brown color.

Notable Features

Distinctive dark color, fine texture, moderate weight, and attractive natural chatoyance under finish.
