Grain Pattern

Mostly irregular, wavy, and cathedral-like flat-sawn grain with pronounced dark streaking and mild crotch-like figure; not quarter-sawn.

Color & Appearance

Weathered medium brown to gray-brown heartwood with darker chocolate streaks and subdued sapwood. Walnut normally darkens and develops warmer amber tones with age, while exposed surfaces can gray.

Hardness (Janka)

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has reasonable decay and insect resistance but is not ideal for prolonged exterior exposure.

Value & Age

Estimated Market ValueNot an official valuation

Typical clear walnut: roughly $8–$20 per board foot; highly figured or wide premium stock can exceed this.

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 dated from this photograph; the gray patina and surface wear suggest previously exposed or older finished wood, not necessarily old-growth timber.

Common Uses

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

Geographic Origin

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

Workability

Machines, sands, glues, and finishes well; irregular grain may cause localized tear-out, so use sharp cutters and light passes.

Finish Recommendations

Clean and lightly sand, then use oil, shellac, lacquer, or satin polyurethane; a clear finish will deepen contrast and warmth.

Notable Features

Distinctive dark streaking, attractive luster, and strong decorative figure; moderate dimensional stability.
