Grain Pattern

Mostly straight to gently irregular grain, with subtle cathedral-like bands and mild wavy figure; appears flat-sawn or mixed-sawn.

Color & Appearance

Muted gray-brown to medium brown heartwood with darker streaking and relatively pale sapwood; weathered oxidation has reduced contrast and luster.

Hardness (Janka)

About 1,010 lbf Janka—Medium hardness.

Durability & Decay Resistance

Moderately durable; heartwood offers fair decay resistance but is not highly weather-resistant, and sapwood is more vulnerable to insects.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; figured or premium wide stock may cost substantially 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 board appears weathered or aged, but visible wear cannot reliably establish its chronological age; likely years to decades of exposure or storage.

Common Uses

Furniture, cabinetry, architectural millwork, gunstocks, paneling, flooring, veneer, and turning.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well; interlocked areas can tear out, and darker dust may obscure defects.

Finish Recommendations

Sand progressively to about 180–220 grit, then apply oil, lacquer, shellac, or polyurethane; a clear finish will deepen the brown color and contrast.

Notable Features

Distinctive dark streaking, moderate weight, good dimensional stability, and a characteristic mild walnut scent when freshly cut.
