Grain Pattern

Mostly straight, fine and moderately open grain with subtle cathedral variation; appears flat-sawn. No pronounced figured pattern is visible.

Color & Appearance

Warm medium brown heartwood with muted purplish-gray and darker streaks; sapwood is largely absent or blended. Walnut typically lightens slightly and develops warmer amber tones with age and light.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood offers useful decay resistance, while sapwood is more vulnerable to insects and rot. Not rated for prolonged exterior exposure.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for clear kiln-dried walnut; premium wide or figured 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 dated visually; it appears like a relatively recent, cleanly machined board rather than visibly antique material.

Common Uses

Furniture, cabinetry, architectural panels, flooring, gunstocks, veneers, carving, and turning.

Geographic Origin

Eastern and central North America, especially the United States and southern Canada; commonly grown in the Midwest and Appalachians.

Workability

Machines, sands, glues, and finishes well, though reversing grain can cause localized tearout. Pre-drilling is helpful and cutting edges should be sharp.

Finish Recommendations

Apply a clear oil, hardwax oil, lacquer, or polyurethane after sanding to 180–220 grit; a wash coat or sanding sealer can help equalize absorption.

Notable Features

Moderate weight, attractive subdued luster, good dimensional stability, and characteristic walnut color variation.
