Grain Pattern
Mostly straight grain with mild irregularity around a small knot; the broad face appears flat-sawn. End grain is not visible.
Color & Appearance
The boards show brown to gray-brown tones with darker streaks and uneven surface oxidation. Freshly cut walnut is usually richer brown; light exposure can make it lighter and less saturated.
Hardness (Janka)
1,010 lbf — Medium.
Durability & Decay Resistance
Moderately durable; heartwood has some decay and insect resistance, while sapwood is less resistant.
Value & Age
Common kiln-dried walnut lumber is roughly US$8–18 per board foot; grade, thickness, and region affect price.
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; surface grayness may reflect oxidation or finish rather than age.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, and turning.
Geographic Origin
Native to eastern North America, especially the central and eastern United States.
Workability
Generally machines and finishes well; sharp tools help prevent tearout near knots or irregular grain. It glues and screws readily.
Finish Recommendations
Sand evenly and apply oil, shellac, lacquer, or polyurethane; test first because existing oxidation or finish may alter color.
Notable Features
Walnut often has attractive dark streaking and a smooth, occasionally lustrous finish; this sample shows modest natural variation.
