Grain Pattern

Mostly straight to gently irregular grain, with broad cathedral-like figure suggesting flat-sawn stock; no clear distinctive figured pattern.

Color & Appearance

Medium-to-dark brown with warmer reddish areas and darker streaks. Surface finish and lighting may affect appearance; walnut often lightens or becomes more golden with age and light.

Hardness (Janka)

1,010 lbf — Medium (Janka).

Durability & Decay Resistance

Moderately durable; heartwood has useful 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 ordinary kiln-dried walnut; grade, dimensions, and region substantially 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 estimated reliably from the image; patina and surface marks alone do not establish age.

Common Uses

Furniture, cabinetry, flooring, veneer, turning, and decorative panels.

Geographic Origin

Black walnut is native to eastern and central North America.

Workability

Generally machines, sands, and glues well; sharp tools help produce clean surfaces, and grain reversals can cause localized tearout.

Finish Recommendations

Clean and lightly sand before applying oil, shellac, lacquer, or clear polyurethane; test first, as finish can deepen the brown color.

Notable Features

Typically has attractive brown heartwood and good dimensional stability; the pictured surface appears finished and shows wear or scratches.
