Grain Pattern
Mostly straight, fine to moderately coarse grain with subtle cathedral-like variation and darker mineral streaking; appears flat-sawn or plain-sawn.
Color & Appearance
Heartwood is medium chocolate brown with darker brown streaks; sapwood is pale tan and sharply contrasting. Walnut can mellow slightly lighter and warmer with age and light exposure.

1,010 lbf Janka — Medium
Durability & Decay Resistance
Moderately Durable; heartwood has reasonable decay resistance but is not generally rated for prolonged exterior exposure.
Value & Age
Approximately $8–$18 per board foot for ordinary kiln-dried walnut; figured or exceptionally wide stock may cost substantially 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; the clean surfaces show little evidence of age or patina, suggesting recently milled or lightly used stock.
Common Uses
Furniture, cabinetry, flooring, gunstocks, architectural millwork, veneer, carving, and turned objects.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachian regions.
Workability
Generally machines, planes, sands, glues, and finishes well; interlocked areas may show minor tearout. Pre-drilling is advisable, and the wood can mildly blunt tools over extended work.
Finish Recommendations
Use a clear oil, wiping varnish, lacquer, shellac, or polyurethane after sanding to 180–220 grit. A washcoat or conditioner can reduce uneven absorption near sapwood and streaks.
Notable Features
Distinctive dark heartwood, pale sapwood contrast, moderate natural luster, and good dimensional stability; the dark line may be mineral streaking or a natural internal mark.
