Grain Pattern
Mostly straight, fine to moderately coarse grain with mild cathedral and irregular figure; appears flat-sawn. End grain is not clearly visible.
Color & Appearance
Gray-brown to chocolate-brown heartwood with lighter sapwood and subdued luster; walnut commonly lightens or develops warmer amber tones with age and light.
Hardness (Janka)
1,010 lbf Janka — Medium.
Durability & Decay Resistance
Moderately Durable; heartwood has useful resistance to decay and insects, while sapwood is less resistant. Not ideal for prolonged exterior exposure.
Value & Age
Approximately $8–$18 per board foot for ordinary kiln-dried walnut; figured or premium wide stock 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
- The board’s surface wear and oxidation suggest years to decades of exposure, but the wood’s harvesting age cannot be determined visually.
Common Uses
Furniture, cabinetry, architectural millwork, flooring, doors, gunstocks, veneer, and turning.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachians.
Workability
Generally machines, sands, glues, and finishes well, though reversing grain can cause localized tear-out; predrilling is advisable for fasteners.
Finish Recommendations
Sand evenly and apply a penetrating oil, wiping varnish, lacquer, or polyurethane; a wash coat or sanding sealer can reduce uneven absorption.
Notable Features
Distinctive dark color, moderate density, dimensional stability, and characteristic walnut figure; the visible dark marks may be knots, mineral streaks, or old fastener/defect areas.
