Grain Pattern

Mostly straight, longitudinal grain with darker streaks; the visible face appears plain-sawn or rift-like. No distinctive figured pattern is apparent.

Color & Appearance

Central heartwood is medium-to-dark brown with darker streaking; broad pale sapwood borders it. Surface looks unfinished or weathered, so its original luster and aging color are unclear.

Hardness (Janka)

1,010 lbf — Medium (Janka).

Durability & Decay Resistance

Moderately durable; heartwood has some decay resistance, while sapwood is more vulnerable to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

Roughly US$8–20 per board foot for common kiln-dried walnut; grade, dimensions, 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; surface wear and discoloration do not establish age.

Common Uses

Furniture, cabinetry, flooring, veneer, gunstocks, turning, and musical instruments.

Geographic Origin

Black walnut is native to eastern North America.

Workability

Generally machines, sands, glues, and finishes well; sharp tools help limit tearout around irregular grain.

Finish Recommendations

Sand evenly and apply oil, shellac, lacquer, or clear polyurethane; a clear finish deepens the brown color. Avoid assuming the pale edges are sapwood without closer inspection.

Notable Features

The contrasting pale sapwood and brown heartwood are characteristic of walnut; no scent or other distinctive feature can be confirmed visually.
