Grain Pattern

Appears mostly straight with coarse, open texture; the exposed surface may be rough-sawn or weathered, so figure and cut orientation are unclear.

Color & Appearance

Janka about 1,010 lbf — Medium.

Approximately $8–$18 per board foot for common kiln-dried walnut; figured or premium clear 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 image; roughness and darkening indicate exposure or oxidation rather than a specific age.

Common Uses

Furniture, cabinetry, flooring, gunstocks, doors, veneer, turnings, and decorative millwork.

Geographic Origin

Eastern and central North America, especially the Midwest and eastern United States.

Workability

Generally machines, sands, glues, and finishes well, though irregular grain can tear out and silica or grit in weathered wood can dull tools.

Finish Recommendations

Use a clear oil, shellac, lacquer, or polyurethane; sand progressively and apply conditioner or washcoat if sapwood staining is uneven.

Notable Features

Distinctive dark heartwood, attractive color variation, moderate weight, and good dimensional stability.
