Grain Pattern

Broadly irregular to gently wavy, with subdued cathedral-like figure; the image does not clearly show end grain or a definitive cut orientation.

Color & Appearance

Brown to deep chocolate heartwood with darker streaking and relatively light sapwood at the top. Walnut commonly lightens or develops warmer amber tones with age and finish, with moderate natural luster.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately Durable; heartwood has useful resistance to decay and insects, but is not intended as an exceptionally weather-resistant wood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$20 per board foot for common kiln-dried walnut; figured or premium clear stock may exceed $30.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Not reliably determinable from this photograph; the darkened surface suggests oxidation, finish, or wear rather than a specific age.

Common Uses

Furniture, cabinetry, doors, architectural millwork, flooring, gunstocks, veneer, and decorative turning.

Geographic Origin

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

Workability

Generally machines, planes, sands, glues, and finishes well; irregular grain can cause localized tear-out, and predrilling is advisable for fasteners.

Finish Recommendations

Use a clear oil, shellac, lacquer, or satin polyurethane; seal end grain and test for color shift, as finishes deepen walnut’s brown tones.

Notable Features

Distinctive dark color, occasional purple-brown cast, attractive contrast with pale sapwood, and generally stable movement after drying.
