Grain Pattern

Mostly straight to irregular, with broad flowing dark streaks and a prominent cathedral-like figure suggesting flat-sawn stock. No clear evidence of special figure such as burl or bird’s-eye.

Color & Appearance

Medium brown with darker chocolate-brown streaks and lighter tan areas; the visible face appears aged or finished. Walnut typically lightens with prolonged light exposure.

Value & Age

Estimated Market ValueNot an official valuation

Roughly $8–$20 per board foot for common kiln-dried walnut; grade and region substantially affect price.

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; surface color and wear may reflect finish or exposure rather than age.

Common Uses

Furniture, cabinetry, flooring, veneer, turning, and decorative joinery.

Geographic Origin

Black walnut is native to eastern and central North America.

Workability

Generally machines and finishes well; irregular grain can tear out during planing. Glues and holds fasteners well with appropriate pilot holes.

Finish Recommendations

Sand evenly and use oil, shellac, lacquer, or clear polyurethane; a clear finish enhances the contrast without obscuring the grain.

Notable Features

Walnut is valued for its rich brown color and attractive contrasting grain; this sample shows pronounced dark streaking.
