Grain Pattern

Mostly irregular to wavy, with swirling growth rings and mild crotch-like figure; appears flat-sawn. End grain is only partly visible and obscured by rough sawing.

Color & Appearance

Brown heartwood with darker streaks and pale gray-brown sapwood/bark edge; walnut commonly lightens or warms subtly with age and develops satin luster when finished.

Hardness (Janka)

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

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

Value & Age

Estimated Market ValueNot an official valuation

About $8–$20 per board foot for ordinary air-dried walnut; figured, wide, dry slabs may exceed $30.

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 tree’s age cannot be determined from the photograph; the slab appears freshly cut or only recently weathered, not reliably antique.

Common Uses

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

Geographic Origin

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

Workability

Generally machines and sands well, though irregular grain can tear out; glues, screws, and finishes reliably. Sharp blades are recommended.

Finish Recommendations

Air-dry thoroughly, sand evenly, then use oil, shellac, lacquer, or polyurethane; a clear finish best preserves the brown color and figure.

Notable Features

Dark contrasting streaks, attractive irregular grain, moderate weight, and walnut’s characteristic mild earthy scent when freshly worked.
