Grain Pattern

Predominantly straight, fine-to-medium grain with mild cathedral/flat-sawn variation; no clear decorative figure visible.

Color & Appearance

Dark chocolate-brown upper boards contrast with lighter honey-brown lower components, possibly reflecting heartwood versus sapwood or different woods/finishes. Walnut commonly lightens or develops warmer amber tones with age 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–$16 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
Not reliably determinable from a photograph; apparent wear and finish suggest an older finished piece, but not necessarily antique.

Common Uses

Furniture, cabinetry, flooring, architectural millwork, gunstocks, veneer, and turning.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well; interlocked grain can cause localized tear-out, and predrilling is advisable.

Finish Recommendations

Clean gently, lightly abrade, and use wiping oil, shellac, lacquer, or clear polyurethane; test first because existing finish and color variation affect results.

Notable Features

Warm brown color, moderate weight, good dimensional stability, and attractive natural luster; the contrasting lighter parts may indicate sapwood or mixed species.
