Grain Pattern

Mostly straight, fine and moderately open-grained, with subtle cathedral-like variation and occasional streaking; appears plainsawn or lightly riftsawn.

Color & Appearance

Medium chocolate-brown heartwood with subdued lighter/darker streaks; sapwood is largely absent from the visible face. Walnut typically lightens slightly and develops a warmer amber patina with age.

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 premium exterior-weathering wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$15 per board foot for clear, kiln-dried domestic walnut; figured or exceptionally wide stock can 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 newly milled or recently surfaced; visible patina and wear do not establish tree age.

Common Uses

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

Geographic Origin

Eastern and central North America, especially the United States and southern Canada.

Workability

Generally machines, sands, glues, and finishes well; interlocked areas may tear out during planing, and predrilling is advisable for fasteners.

Finish Recommendations

Apply a clear oil, wiping varnish, lacquer, or polyurethane after thorough sanding; a wash coat or sealer can help even absorption and preserve color.

Notable Features

Distinctive warm brown color, moderate weight, fine texture, and attractive natural luster; the shown piece has restrained rather than highly figured grain.
