Grain Pattern

Mostly straight, with fine linear texture and occasional irregular dark streaking; appears flat-sawn or plain-sawn. No clear decorative figure is visible.

Color & Appearance

Brown to chocolate-brown heartwood with darker streaks and little visible sapwood; moderate natural luster. Walnut commonly lightens or develops warmer amber tones with age and ultraviolet exposure.

Hardness (Janka)

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately durable; heartwood offers moderate decay resistance but is not naturally weatherproof, with limited insect resistance.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for common kiln-dried lumber; figured or exceptional grades 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
Cannot be reliably estimated from this close-up; surface oxidation and wear suggest an aged or previously finished sample, not necessarily old wood.

Common Uses

Furniture, cabinetry, flooring, gunstocks, architectural millwork, veneer, turning, and decorative panels.

Geographic Origin

Eastern and central North America, especially the Midwest and eastern United States.

Workability

Generally machines, planes, sands, glues, and finishes well; occasional tearout may occur around irregular grain, and dark dust can obscure surface defects.

Finish Recommendations

Sand evenly, seal end grain, then use oil, shellac, lacquer, or clear polyurethane; a clear finish preserves the brown color, while UV exposure gradually warms it.

Notable Features

Distinctive dark color, relatively fine texture, good dimensional stability, and attractive contrast between growth bands and streaks.
