Grain Pattern
Mostly straight, fine-to-medium grain with subtle variation; the image shows a pronounced dark longitudinal streak. No clear figured pattern or end grain is visible.
Color & Appearance
Brown to medium-dark brown with darker streaking; sapwood and luster are not reliably distinguishable here. Walnut often lightens somewhat with prolonged light exposure.

1,010 lbf; Medium.
Durability & Decay Resistance
Moderately durable; heartwood has some decay resistance, while sapwood is more susceptible to insects and rot.
Value & Age
Typically about $8–$15 per board foot for common kiln-dried lumber; figured or premium-grade stock can 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
- Not estimable from this close-up; visible color alone does not establish age or patina.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, and musical instruments.
Geographic Origin
Eastern and central North America, especially the eastern United States.
Workability
Generally machines, sands, and glues well; sharp tools help produce clean surfaces. Check streaks and grain changes for localized tearout.
Finish Recommendations
Sand evenly and use oil, shellac, lacquer, or clear polyurethane; a clear finish preserves the brown color. Test first, as streaks may absorb finish differently.
Notable Features
Valued for rich brown color and attractive contrast; walnut is relatively stable and commonly used for fine furniture.
