Grain Pattern
Predominantly straight to gently irregular, with subtle cathedral-like variation and a fairly fine, even texture; appears flat-sawn or plain-sawn.
Color & Appearance
Dark chocolate-brown heartwood with lighter brown-gray variation and little visible sapwood. Satin luster is present; walnut commonly lightens slightly and develops warmer amber tones with age and light.

Janka about 1,010 lbf — Medium.
Durability & Decay Resistance
Moderately durable; heartwood offers reasonable decay resistance but is not considered highly weatherproof. Insect resistance is moderate.
Value & Age
Approximately $8–$18 per board foot for good kiln-dried walnut; premium wide or figured boards may exceed $25.
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 determinable from this finished photograph; the surface appears relatively clean and recently finished, without strong antique patina.
Common Uses
Furniture, cabinetry, flooring, architectural millwork, gunstocks, veneer, turning, and musical-instrument components.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachian regions.
Workability
Generally machines and sands well, though irregular grain can produce localized tearout. It glues, screws, nails, and finishes reliably; sharp cutters improve results.
Finish Recommendations
Use a clear oil, hardwax oil, lacquer, shellac, or polyurethane; seal end grain and apply thin coats after thorough sanding. A clear finish best preserves the dark color.
Notable Features
Moderate natural luster, attractive dark color, dimensional stability, and occasional purple-gray or chocolate streaking.
