Grain Pattern

Appears mostly straight to mildly wavy, with broad cathedral-like figure on the face; end-grain detail is insufficient for certainty.

Color & Appearance

Warm chocolate-brown heartwood with lighter brown streaking and pale sapwood; walnut generally develops a richer, slightly lighter golden-brown patina with age.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; reasonable resistance to decay, but not intended as an unqualified exterior-weathering wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for kiln-dried, clear walnut; figured or wide 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
Cannot be reliably estimated from the photograph; the pieces appear recently cut or machined, with little visible oxidation or wear.

Common Uses

Furniture, cabinetry, flooring, veneer, gunstocks, turned objects, and premium joinery.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well; grain reversal can cause localized tear-out, and sharp tools are preferred.

Finish Recommendations

Use a clear oil, shellac, lacquer, or polyurethane after thorough sanding; a clear finish preserves contrast, while oil deepens the brown color.

Notable Features

Distinctive dark color, attractive luster, moderate weight, and occasional wavy or figured grain; the image may show laminated or multiple cut pieces.
