Grain Pattern

Predominantly straight, fine-to-medium texture, with subtle cathedral/curly variation possible; the image shows no clear end grain.

Color & Appearance

Warm medium brown with darker streaking and moderate natural luster; walnut commonly lightens slightly and develops a richer amber-brown tone with age and light.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has fair decay and insect resistance, while sapwood is substantially less resistant.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried walnut; premium figured or wide boards 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
Not reliably determinable from this photograph; apparent finish wear suggests an older finished component, not necessarily old wood.

Common Uses

Furniture, cabinetry, paneling, flooring, veneer, gunstocks, turning, and interior architectural trim.

Geographic Origin

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

Workability

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

Finish Recommendations

Use dewaxed shellac or a compatible sealer, followed by oil, lacquer, or polyurethane; test for color shift and apply thin coats.

Notable Features

Distinctive dark streaking, moderate weight, good dimensional stability, and attractive subdued figure.
