Grain Pattern

Mostly straight, fine-to-medium grain with pronounced dark longitudinal streaks; appears flat-sawn or plain-sawn. No clear figured pattern is visible.

Color & Appearance

Medium brown to dark brown with contrasting darker streaks; sapwood is not clearly visible. Walnut commonly lightens or develops warmer tones with age and light exposure.

Hardness (Janka)

1,010 lbf — Medium (near the stated medium/hard boundary).

Durability & Decay Resistance

Moderately durable heartwood; some resistance to decay, but not especially weather- or insect-resistant.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$8–$18 per board foot for typical kiln-dried lumber; grade, thickness, 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
Cannot be reliably estimated from this image; no clear patina or wear indicators are shown.

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, sands, glues, and finishes well; sharp cutters help avoid tearout in irregular grain. Pilot holes are useful for screws.

Finish Recommendations

Sand evenly and use oil, shellac, lacquer, or clear polyurethane; a clear finish preserves the brown color. Test first, as finishes can deepen the contrast.

Notable Features

Known for rich brown color, attractive figure in selected boards, and good dimensional stability; this sample shows strong linear color variation.
