Grain Pattern

Irregular, swirling flat-sawn grain with localized crotch-like figure around the knot; moderately open texture.

Color & Appearance

Chocolate-brown to purplish heartwood with lighter brown streaking; sapwood is not prominent. Walnut generally lightens subtly and develops warmer amber tones with age.

Durability & Decay Resistance

Moderately Durable; heartwood has useful resistance to decay and insects, though exposed weathering is not its primary strength.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $10–$25 per board foot for clear, kiln-dried walnut; figured or premium 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
Cannot be dated from a photograph; the clean faces and sharp edges suggest a recently milled or lightly aged blank.

Common Uses

Furniture, cabinetry, veneer, gunstocks, flooring, turning, carving, and decorative boxes.

Geographic Origin

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

Workability

Generally machines and sands well, but swirling grain can cause localized tear-out; predrilling improves fastener work, and standard glues perform well.

Finish Recommendations

Apply a penetrating oil, wiping varnish, lacquer, or satin polyurethane after sanding to 180–220 grit; seal end grain carefully and use a clear finish to preserve color.

Notable Features

Distinctive dark color, attractive figure, moderate weight, and strong natural luster; the visible knot adds character but reduces clear structural uniformity.
