Grain Pattern

Mostly straight to gently wavy, with prominent cathedral/arched figure indicating flatsawn material; pores appear large and diffuse-porous.

Color & Appearance

Muted gray-brown to chocolate brown heartwood with lighter sapwood; the surface appears weathered or oxidized, reducing color contrast. Walnut generally lightens slightly and develops warmer amber tones with age.

Hardness (Janka)

About 1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful decay and insect resistance, but exposed weathering will gray and eventually degrade it.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; premium wide or highly figured stock can exceed $25.

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 image supports apparent surface aging, but not a reliable chronological age; it may be weathered, reclaimed, or simply unfinished.

Common Uses

Furniture, cabinetry, flooring, gunstocks, veneer, turning, carving, and decorative panels.

Geographic Origin

Eastern and central North America, especially the United States and southern Canada.

Workability

Generally machines, sands, glues, and finishes well; interlocked areas may show modest tear-out, and end grain can absorb finish unevenly.

Finish Recommendations

Sand progressively, seal end grain, then use oil, shellac, lacquer, or clear polyurethane; a clear finish best preserves the brown color.

Notable Features

Naturally attractive dark heartwood, moderate luster, good dimensional stability, and strong contrast between heartwood and sapwood.
