Grain Pattern

Mostly straight, with cathedral-like flatsawn growth patterns, mild waviness, and visible open pores; no strong decorative figure.

Color & Appearance

Brown to chocolate-brown heartwood with lighter gray-brown streaking and comparatively pale sapwood. It gradually lightens or develops a warmer amber cast with oxidation and light exposure.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful decay resistance but is not reliably weatherproof, 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 domestic walnut; figured or premium wide stock may 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 image; the surface appears finished and moderately aged, with no decisive antique-wear indicators.

Common Uses

Furniture, cabinetry, flooring, paneling, gunstocks, turnings, veneer, and musical instruments.

Geographic Origin

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

Workability

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

Finish Recommendations

Use a clear oil, wiping varnish, lacquer, or polyurethane after thorough sanding; an oil-based finish will deepen the brown color and enhance figure.

Notable Features

Distinctive dark color, attractive contrast, moderate luster, and good dimensional stability; walnut commonly has darker mineral streaks.
