Grain Pattern

Mostly straight to gently wavy, flat-sawn grain with pronounced cathedral arches and a small knot/figure near the lower center; no clear specialty figure.

Color & Appearance

Muted medium brown to gray-brown heartwood with subtle darker streaking; sapwood appears pale at the edges. Fresh walnut typically darkens and develops warmer chocolate tones with light exposure, while this piece appears weathered or unfinished.

Hardness (Janka)

Janka approximately 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful resistance to decay and insects, though exposed weathering will eventually degrade it.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$8–18 per board foot for common kiln-dried walnut; premium wide, clear stock can exceed this range.

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; subdued color suggests oxidation, handling, or outdoor exposure rather than a reliably old sample.

Common Uses

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

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well; interlocked or figured areas may tear out, and predrilling is advisable for fasteners.

Finish Recommendations

Sand uniformly, optionally use a penetrating oil for depth, or apply shellac, lacquer, or wiping/polyurethane finish; test first because color can vary.

Notable Features

Naturally attractive contrast, moderate dimensional stability, and a characteristic mild walnut scent when freshly cut.
