Grain Pattern

End grain shows concentric growth rings and a central irregular break; face-grain figure and sawing orientation cannot be assessed.

Color & Appearance

Heartwood appears dark brown to nearly black, with a lighter gray-brown outer zone; lighting and surface condition may distort color. Walnut typically lightens or shifts brown with age and exposure.

Hardness (Janka)

1,010 lbf — Medium (typical black walnut value)

Durability & Decay Resistance

Moderately Durable; heartwood has some decay resistance, while sapwood is more susceptible to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

Roughly US$8–$20 per board foot for typical kiln-dried lumber; grade, dimensions, and local market strongly affect price.

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 estimate from this image; ring count, patina, and wear history are not sufficiently visible.

Common Uses

Furniture, cabinetry, flooring, gunstocks, veneer, turning, and decorative objects.

Geographic Origin

Eastern and central North America; black walnut is native to the eastern United States and parts of southeastern Canada.

Workability

Generally machines and sands well, though irregular grain can tear out; glues and finishes readily. Pre-drilling is useful near edges.

Finish Recommendations

Sand evenly and use oil, shellac, lacquer, or clear polyurethane; test first because the dark color and end-grain absorption can vary.

Notable Features

Valued for dark heartwood, attractive grain, and good stability; the visible central damage may be a split or decay feature.
