Grain Pattern

Mostly straight to mildly wavy grain, with darker longitudinal streaking; the image shows flat-sawn appearance and no clear special figure.

Color & Appearance

Deep chocolate-brown heartwood with subdued lighter streaks; sapwood is not visible. Dark finish or age-related oxidation appears likely, limiting natural color assessment.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has moderate resistance to decay and insects, but is not a premier exterior wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for clear kiln-dried walnut; figured or exceptional stock can be 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 reliably estimated from the photograph; the dark surface may reflect finish rather than age. It appears to be finished furniture wood, not necessarily antique.

Common Uses

Fine furniture, cabinetry, tables, architectural millwork, gunstocks, veneer, and decorative turning.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachians.

Workability

Generally machines, sands, glues, and finishes well, though interlocked grain may cause localized tear-out. Pre-drilling is advisable for fasteners.

Finish Recommendations

Clean gently, test compatibility, and use shellac, lacquer, oil, or polyurethane; a satin clear coat will preserve the dark appearance. Avoid aggressive sanding that could cut through veneer.

Notable Features

Warm brown color, attractive understated grain, good dimensional stability, and a naturally smooth luster when finished.
