Grain Pattern

Mostly straight, with broad growth-ring bands; appears plain-sawn or rough-sawn. No distinctive figured grain is visible.

Color & Appearance

Muted brown to gray-brown surface, likely darkened by oxidation, dirt, or age; heartwood/sapwood distinction is unclear, and the surface looks unfinished and rough.

Hardness (Janka)

1,010 lbf; Medium (if black walnut).

Durability & Decay Resistance

Moderately durable; walnut heartwood resists decay better than sapwood, but is not weatherproof.

Value & Age

Estimated Market ValueNot an official valuation

Rough black walnut commonly varies around $8–$20 per board foot; grade, dimensions, drying, and region strongly 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 estimate reliably from this photo; surface weathering and saw marks do not establish the tree’s age or time since milling.

Common Uses

Furniture, cabinetry, flooring, veneer, gunstocks, turning, and decorative work.

Geographic Origin

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

Workability

Generally machines and sands well, glues readily, and holds fasteners; rough or cross-grain areas may tear out during planing.

Finish Recommendations

Sand progressively, then use oil, shellac, lacquer, or polyurethane; test first because the aged surface may absorb finish unevenly.

Notable Features

Walnut is valued for its brown heartwood and often darkens with light exposure; this sample’s stamped lettering and rough surface are not diagnostic.
