Grain Pattern
Mostly straight, fine-to-medium grain with subtle irregular streaks; appears flat-sawn, with no obvious figured pattern.

Muted gray-brown face with darker streaks and small blemishes; fresh black walnut is usually chocolate brown with lighter sapwood and can lighten or yellow under prolonged light exposure.
Hardness (Janka)
1,010 lbf — Medium
Durability & Decay Resistance
Moderately durable; heartwood has fair decay resistance, while sapwood is more susceptible to insects and rot.
Value & Age
Approximately US$8–20 per board foot for common kiln-dried lumber; grade and region strongly 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
- Not reliably estimable from this image; surface discoloration alone does not establish age.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, and musical instruments.
Geographic Origin
Eastern North America, especially the central and eastern United States.
Workability
Generally machines and finishes well; sharp tools help prevent tearout in irregular grain. Glues readily and holds screws well with pilot holes.
Finish Recommendations
Sand evenly and apply oil, shellac, lacquer, or polyurethane; test on an offcut because finish can deepen the brown tone.
Notable Features
Typically valued for rich brown heartwood and good dimensional stability; this sample’s subdued gray tone may result from surface treatment, oxidation, or lighting.
