Grain Pattern

Mostly straight, moderately open grain with subtle cathedral and irregular areas; no strong figured pattern visible. Face grain appears flat-sawn.

Color & Appearance

Medium chocolate-brown heartwood with gray-purple cast and lighter sapwood or weathered areas; walnut generally lightens and becomes warmer under oxidation and finish.

Hardness (Janka)

Janka about 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful resistance to decay and insects, but is not a premier exterior-weathering wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$8–20 per board foot for clear, kiln-dried retail lumber; figured or exceptional stock can cost 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 this photograph; surface oxidation and handling suggest a seasoned or previously worked piece, not necessarily antique.

Common Uses

Furniture, cabinetry, flooring, gunstocks, architectural millwork, veneer, turning, and smaller craft projects.

Geographic Origin

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

Workability

Generally machines, sands, glues, and finishes well, though irregular grain can produce localized tearout. Pre-drilling is advisable for screws and nails.

Finish Recommendations

Apply sanding sealer followed by oil, shellac, lacquer, or polyurethane; an oil finish emphasizes depth and chatoyance. Test first because color and absorption vary.

Notable Features

Moderate weight, distinctive walnut color, attractive natural luster, and a faint characteristic odor when freshly cut.
