Grain Pattern

Predominantly straight, fine-to-medium textured, with subtle cathedral and occasional wavy streaking; appears flat-sawn or veneer-faced.

Color & Appearance

Muted chocolate-brown to gray-brown heartwood with lighter sapwood-like streaks and moderate natural luster; walnut commonly warms and lightens slightly with age and exposure.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately Durable; heartwood has useful resistance to decay and insects, though it is not a premier exterior wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; premium figured or wide clear stock may be substantially higher.

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 determined reliably from this clean, apparently new surface; no convincing patina or wear indicators are visible.

Common Uses

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

Geographic Origin

Eastern and central North America, especially the Mississippi and Ohio River valleys.

Workability

Generally machines, sands, glues, and finishes well; interlocked areas can tear out, and sharp tooling is preferred.

Finish Recommendations

Apply a sanding sealer followed by oil, shellac, lacquer, or clear polyurethane; oil accentuates contrast and depth. Test first because porous areas may absorb unevenly.

Notable Features

Recognizable dark streaking, attractive subdued figure, good dimensional stability, and a characteristic mild walnut odor when freshly cut.
