Grain Pattern

Mostly straight, fine to moderately coarse grain with subtle cathedral and occasional wavy figure; appears flat-sawn or mildly rift-sawn.

Color & Appearance

Medium chocolate-brown heartwood with lighter brown-gray variation and relatively pale sapwood; moderate natural luster. It commonly lightens or warms slightly with age and light.

Hardness (Janka)

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately Durable; heartwood has reasonable decay and insect resistance, while sapwood is substantially less resistant.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$8–18 per board foot for clear kiln-dried lumber; figured or exceptional 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 board appears relatively fresh or recently surfaced; visible color cannot reliably establish tree or sample age.

Common Uses

Furniture, cabinetry, flooring, architectural millwork, gunstocks, veneer, turning, and decorative boxes.

Geographic Origin

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

Workability

Generally machines, planes, sands, glues, and finishes well, though reversing grain may cause localized tear-out; predrilling is useful for fasteners.

Finish Recommendations

Apply a penetrating oil, wiping varnish, lacquer, shellac, or clear polyurethane after sanding to 180–220 grit; test finish because color can vary.

Notable Features

Distinctive dark color, attractive grain, moderate weight, and good dimensional stability; walnut often develops a rich patina.
