Broad, mostly straight to slightly wavy grain with dark streaking and mild cathedral-like figure; the visible piece appears flat-sawn or plain-sawn.

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has reasonable 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 typical clear walnut; figured or exceptional stock may be considerably higher.

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 dated from this image; surface oxidation suggests seasoned stock, but not necessarily antique or reclaimed.

Common Uses

Furniture, cabinetry, gunstocks, architectural millwork, veneer, turning, and 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 grain can tear out, and sharp cutters are recommended.

Finish Recommendations

Apply a sanding sealer followed by oil, shellac, lacquer, or clear polyurethane; test first because finishes can strongly deepen the color.

Notable Features

Distinctive dark color, moderate density, good dimensional stability, and attractive natural contrast.
