Grain Pattern

Mostly straight to irregular, with growth-ring arcs visible on the end grain; the rough bark and round log do not show enough face grain to assess figure.

Color & Appearance

Brown to chocolate-brown heartwood with lighter gray-brown sapwood and moderate color variation; walnut generally lightens or becomes warmer brown with age and light exposure.

Hardness (Janka)

Janka about 1,010 lbf — Medium.

Durability & Decay Resistance

Moderately durable; heartwood offers useful resistance to decay and insects, while sapwood is less resistant. Not rated for prolonged weather exposure without protection.

Value & Age

Estimated Market ValueNot an official valuation

Rough walnut log/slab material: approximately $5–$15 per board foot; figured or kiln-dried stock may be substantially higher.

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 tree’s age cannot be determined reliably from this photograph; the piece appears freshly cut or recently exposed, with no established patina.

Common Uses

Furniture, cabinetry, gunstocks, flooring, veneer, turning, carving, and decorative slabs.

Geographic Origin

Eastern and central North America, especially the Midwest and eastern United States.

Workability

Generally machines and sands well, though bark inclusions, checks, and irregular grain can cause tearout; predrilling is advisable and sharp tools are important.

Finish Recommendations

Air- or kiln-dry thoroughly, remove loose bark, and seal checks before finishing. Oil, shellac, lacquer, or polyurethane all work well; test for uneven absorption near sapwood and inclusions.

Notable Features

Walnut is relatively heavy, stable, and prized for its dark heartwood; this sample shows bark inclusions, end checks, and possible early spalting or staining.
