Grain Pattern

Mostly straight to gently wavy, flat-sawn grain with subtle cathedral figure and mild color striping; no clear end grain is visible.

Color & Appearance

Rich chocolate-brown heartwood with lighter tan sapwood, strong natural variation, and moderate luster. Walnut commonly lightens or turns warmer amber-brown with age and light.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood offers reasonable decay resistance, while sapwood is more vulnerable to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for clear, kiln-dried walnut; figured or wide slabs 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 dated from the photograph; the surface appears relatively recently finished, with no dependable patina or wear evidence.

Common Uses

Fine furniture, cabinetry, gunstocks, flooring, veneer, turning, carving, and musical instruments.

Geographic Origin

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

Workability

Generally machines and sands well, though reversing grain can cause tear-out. It glues and finishes reliably; predrilling is advisable near edges.

Finish Recommendations

Use a clear penetrating oil, hardwax oil, shellac, lacquer, or polyurethane after sanding; a clear finish best preserves the color contrast.

Notable Features

Distinctive dark heartwood, attractive grain variation, moderate dimensional stability, and good polishability.
