Grain Pattern

Mostly straight to gently wavy, with broad cathedral-like areas and mild swirling; likely flat-sawn. No clear specialty figure is visible.

Color & Appearance

Weathered gray-brown surface with warmer tan to brown areas and darker streaking; freshly exposed walnut typically becomes rich chocolate brown and may lighten or amber slightly with age.

Hardness (Janka)

1,010 lbf Janka; Medium.

Durability & Decay Resistance

Moderately durable; heartwood offers useful resistance to decay and insects, while sapwood is substantially less resistant.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$20 per board foot for ordinary dry lumber; figured or wide premium slabs may be substantially higher.

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 board’s age cannot be determined visually; surface weathering suggests outdoor exposure or storage, not necessarily old wood.

Common Uses

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

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachians.

Workability

Generally machines and sands well, though grain changes can cause localized tearout; glues, screws, and finishes reliably.

Finish Recommendations

Plane or sand past the weathered layer, then use wiping oil, shellac, lacquer, or polyurethane; a clear finish will emphasize color and figure.

Notable Features

Moderate weight, attractive dark heartwood, good dimensional stability, and strong contrast between heartwood and sapwood.
