Grain Pattern

Mostly straight to mildly irregular, with long cathedral-like bands and occasional wavy figure; appears flat-sawn.

Color & Appearance

Dark brown to chocolate heartwood with lighter brown streaking; sapwood is largely absent or obscured. Weathering has muted the luster and produced gray-brown patina.

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood offers moderate decay resistance, while exposed surfaces can weather and deteriorate. Insect resistance is limited to moderate.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for sound, dry walnut; weathered or reclaimed material may vary widely.

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 sample’s weathering and construction wear suggest decades of exposure or reuse, but age cannot be determined reliably from the photograph.

Common Uses

Furniture, doors, paneling, cabinetry, flooring, gunstocks, veneer, and decorative joinery.

Geographic Origin

Native primarily to eastern and central North America, especially the Midwest and Appalachians.

Workability

Generally machines and hand-tools well, sands smoothly, and glues reliably; grain reversals may cause localized tear-out.

Finish Recommendations

Clean and lightly sand, then use oil, shellac, lacquer, or polyurethane; a clear finish will deepen the brown tones.

Notable Features

Distinctive dark color, attractive grain contrast, moderate weight, and good dimensional stability.
