Grain Pattern

Predominantly straight, fine-to-medium grain with subtle waviness and mild cathedral-like variation; no obvious figured pattern.

Color & Appearance

Chocolate-brown to gray-brown heartwood with lighter sapwood and moderate natural luster. Walnut commonly lightens or develops warmer amber tones with age and finish.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately Durable; heartwood has moderate resistance to decay and insects, but is not intended as an untreated weathering wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for clear kiln-dried lumber; figured or exceptionally wide 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
Cannot be reliably estimated from the photograph; it appears commercially milled and relatively clean, without established patina.

Common Uses

Furniture, cabinetry, flooring, architectural millwork, gunstocks, veneer, turning, and interior trim.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachian regions.

Workability

Generally machines, planes, sands, glues, and finishes well, though changing grain can cause localized tear-out. Pre-drilling is advisable for screws near edges.

Finish Recommendations

Apply a clear oil, shellac, lacquer, or polyurethane after thorough sanding; water-based finishes preserve color but may raise grain slightly.

Notable Features

Moderate weight, dimensional stability, attractive dark color, and good polish-taking ability; the image shows relatively plain, straight-grained stock.
