Grain Pattern
Mostly straight, fine-to-medium textured grain with subtle cathedral/irregular figure and a small knot or mineral streak; appears flat-sawn or plain-sawn.
Color & Appearance
Brown to chocolate-brown heartwood with lighter gray-brown streaking; sapwood appears pale tan. Walnut often develops warmer golden-brown tones and moderate luster with age.
Hardness (Janka)
Janka approximately 1,010 lbf — Medium.
Durability & Decay Resistance
Moderately durable; heartwood has useful resistance to decay and insects, while sapwood is considerably less resistant.
Value & Age
Approximately $8–$18 per board foot for clear, kiln-dried walnut; exceptional figured or wide 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
- The board appears relatively fresh or workshop-aged; surface oxidation and machining marks do not support a reliable chronological age estimate.
Common Uses
Furniture, cabinetry, flooring, gunstocks, doors, architectural millwork, veneer, and turning.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachian regions.
Workability
Generally machines and sands well, though irregular grain can tear out during planing. It glues, screws, and finishes reliably; sharp cutters improve results.
Finish Recommendations
Apply a clear oil, wiping varnish, lacquer, or polyurethane after sanding to 180–220 grit. A washcoat or sealer can reduce uneven absorption.
Notable Features
Recognizable dark heartwood, attractive grain contrast, moderate weight, and good dimensional stability; the image shows no strong specialty figure.
