Grain Pattern
Mostly straight, fine-to-medium grain with dark, irregular streaks. The image shows a broad face, not enough detail to establish sawing orientation or special figure.
Color & Appearance
Medium to dark brown with lighter brown areas and darker streaks; the surface appears aged and worn. Walnut often lightens somewhat with prolonged light exposure.
Hardness (Janka)
1,010 lbf — Medium (near the hard end of the category).
Durability & Decay Resistance
Moderately Durable; heartwood has some decay resistance, but is not intended for prolonged weather exposure.
Value & Age
Roughly US$8–15 per board foot for ordinary kiln-dried lumber; this finished, worn piece cannot be valued from species alone.
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 reliably date from this photo; surface wear and patina suggest use, but not a specific age.
Common Uses
Furniture, cabinetry, interior trim, flooring, veneer, turning, and musical instruments.
Geographic Origin
Eastern North America, especially the central and eastern United States.
Workability
Generally machines and finishes well; sharp tools help limit tearout, especially around changing grain. Glues and fastens readily.
Finish Recommendations
Clean gently, test a discreet area, then use oil, shellac, lacquer, or polyurethane. Avoid aggressive sanding if preserving the aged surface matters.
Notable Features
Walnut commonly has a mild, characteristic earthy scent when freshly cut and can develop attractive color variation; the dark streaks here may be grain, stain, or wear.
