Grain Pattern
Strongly irregular, wavy grain with dark streaks and possible knots; the visible surface does not establish cut orientation or special figure.
Color & Appearance
Warm brown to dark brown with pronounced darker streaks and uneven patina; surface sheen may come from the finish. Heartwood and sapwood cannot be distinguished here.
Hardness (Janka)
1,010 lbf — Medium (Janka; if black walnut).
Durability & Decay Resistance
Moderately durable heartwood; some decay and insect resistance, but not reliably weatherproof.
Value & Age
Roughly $8–$20 per board foot for common kiln-dried walnut; grade, thickness, and region alter price. This finished piece cannot be valued from the image.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Not reliably estimable from this finished, cropped view; wear and darkening may reflect finish or use rather than age.
Common Uses
Furniture, cabinetry, flooring, veneer, carving, turning, and gunstocks.
Geographic Origin
Black walnut is native to eastern North America.
Workability
Generally machines and finishes well; irregular grain may tear out, so use sharp cutters and light passes. Pre-drill near edges when fastening.
Finish Recommendations
Clean gently, test in an inconspicuous spot, then use compatible oil, shellac, lacquer, or polyurethane; avoid aggressive sanding that could remove patina.
Notable Features
Walnut often has attractive color variation and a fine, smooth texture; the striking dark lines here could also be finish, wear, or another species.
