Grain Pattern

Mostly straight to gently irregular, with subtle cathedral-like flatsawn figure; the image shows molded, finished surfaces rather than exposed end grain.

Color & Appearance

Medium chocolate-brown to warm golden brown, with darker streaking and strong aged patina; walnut commonly lightens or reddens under finish and light.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful decay resistance, while sapwood is more vulnerable to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for clear walnut lumber; antique finished millwork value depends chiefly on provenance and condition.

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 darkened finish, wear, scratches, and traditional molding suggest an older finished furnishing, perhaps 50–120 years; wood age itself cannot be determined visually.

Common Uses

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

Geographic Origin

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

Workability

Machines and hand-tools well, sands and glues readily; figured areas may tear out, and dark dust can obscure defects.

Finish Recommendations

Clean gently, test solvents, then use shellac, lacquer, or satin polyurethane; walnut-colored stain is usually unnecessary.

Notable Features

Distinctive dark color, moderate luster, dimensional stability, and attractive grain under clear finishes.
