Grain Pattern

Mostly irregular, flowing grain with subtle curl or crotch-like figure; appears from a turned vessel, so cut orientation is mixed.

Color & Appearance

Warm medium-to-dark brown heartwood with orange highlights, darker streaks, and strong polished luster; walnut generally lightens slightly and may amber with age.

Hardness (Janka)

About 1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful resistance to decay and insects but is not considered highly weatherproof.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$20 per board foot for clear kiln-dried walnut; figured or specialty turning stock may 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
The surface appears worn and patinated, but a photograph cannot reliably establish the wood’s age; likely an older finished object rather than demonstrably antique.

Common Uses

Furniture, cabinetry, gunstocks, architectural millwork, bowls, turning, veneer, and decorative objects.

Geographic Origin

Eastern and central North America, especially the United States and southern Canada.

Workability

Machines, turns, sands, glues, and finishes well; irregular grain can cause localized tear-out, and predrilling is advisable for screws.

Finish Recommendations

Clean gently, then use tung oil, Danish oil, shellac, lacquer, or clear polyurethane; test first because repairs and existing finish may absorb unevenly.

Notable Features

Excellent turning wood with attractive depth, natural luster, and occasional figure; the visible dark surface marks may be patina, staining, or handling wear.
