Grain Pattern

Mostly straight to gently irregular grain, with subtle wavy figure and moderately open pores; appears turned rather than sawn.

Color & Appearance

Chocolate-brown heartwood with lighter brown variation and subdued natural luster; walnut commonly lightens or develops warmer amber tones with age and exposure.

Hardness (Janka)

Janka about 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately Durable; heartwood has reasonable decay resistance, but it is not a premier exterior wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; figured or premium stock may cost substantially 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 wood’s age cannot be determined from this photograph; surface wear suggests a finished, handled object rather than reliably old timber.

Common Uses

Furniture, cabinetry, gunstocks, flooring, veneer, decorative turning, tool handles, and small crafted objects.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachian regions.

Workability

Machines, turns, sands, glues, and finishes well; moderate hardness and open pores are manageable, though end-grain tearout may occur on turning.

Finish Recommendations

Apply sanding sealer or grain filler, then oil, shellac, lacquer, or wiping polyurethane; test first because finishes can significantly deepen the brown color.

Notable Features

Distinctive dark color, attractive understated grain, good dimensional stability, and a smooth polished appearance when turned.
